PATCHING EXADATA
Exadata Database Machine and Exadata Storage Server Supported Versions (Doc ID 888828.1)
A. It is recommended that Exadata
systems with Data Guard configured use the "Standby
First" patching approach.
B. Patching should never be interrupted
due to a connection drop. It is therefore
recommended that you use VNC or the
screen utility.
C. Before patching cells in a rolling
manner, you must check asmdeactivationoutcome
amModestatus and make sure that cells on
all disks are online and that disks can be
deactivated.
First, the Oracle Exadata Patch has 3
different components that should be patched. As we know about Oracle Exadata,
the Exadata rack has a different components, like Cisco Switch, KVM, Power
Distribuion Unit, etc… and we only are responsible for patching the Database
Servers (usually referenced as compute nodes), Storage Servers (usually
referenced as cell nodes) and the Infiniband Switches.
We
can divide the patches in 3 different parts:
Storage Server Patch
Database Server Patch
Infiniband Switches Patch
Order
of Patching
This is an overview in how usually you
should patch all the components, you may also want to wait a few days to
progress to different components, in order to be aware of which component you had
patched before starting facing one bug/error.
Infinibands Switchs
Spine
Leaf
Storage Server Software
Cell nodes
Database Minimal Pack in compute nodes
Database Bundle Patch
Grid Home (if applicable)
Oracle Home
CRS MLR patches (11.2.0.1.0)
Grid Home
Oracle Home (if applicable)
Before starting, I would like to share
and note here 2 documents from My Oracle Support, aka metalink. These notes
must be the first place that you need to go to review before patching the
Exadata environment.
Database Machine and Exadata Storage
Server 11g Release 2 (11.2) Supported Versions (Doc ID. 888828.1)
- This is for the second and third
generation (V2 and X2) for Oracle Exadata, using Sun hardware.
Database Machine and Exadata Storage
Server 11g Release 1 (11.1) Supported Versions (Doc ID. 835032.1)
- This is for the first generation (V1)
for Oracle Exadata, using HP hardware.
Oracle usually updates these documents
for every patch that is released, including different information about that.
-- The Oracle Database software on
Exadata is updated using standard OPatch and the Oracle Universal Installer.
-- Running Exadata with different
storage server software versions is supported, but should be minimized to rolling patching scenarios.
-- Storage server updates require access
to an Unbreakable Linux Network (ULN) based repository .
Platinum covers Exadata storage software and firmware patching, but
the customer must perform
database patching.
A. Dependency issues found during yum
updates require rolling back to a previous release before retrying.
B. Bundle patches applied using opatch
auto ( can )roll back only the database or the grid infrastructure home.
C. Failed OS patches on database servers
( cannot ) be rolled back.
D. Failed storage cell patches are ( not )
rolled back to the previous release automatically.
E. Database server OS updates can be
rolled back using opatch auto -rollback.
F. Dependency issues found during yum
updates should ( not ) be ignored using the force option.
-- Frmware level are maintained automatically
-- Cell patches are maintian across all cell
components and are individual of database patches

Patch 16432033 - Using ISO Image with a
Local Repository README
Quarterly Full Stack Download Patch For
Oracle Exadata (Jul 2013)
Quarterly Full Stack Download Patch For
Oracle Exadata (Oct 2013)
It is mandatory to
know which components/tools are running on which servers on Exadata;
Here is the list;
DCLI -> storage cell and compute nodes, execute cellcli commands on multiple storageservers
ASM -> compute nodes -- it is ASM instance basically
RDBMS -> compute nodes -- it is Databas software
MS-> storage cells, provides a Java interface to the CellCLI command line interface, as well as providing an interface for Enterprise Manager plugins.
RS -> storage cells,RS, is a set of processes responsible for managing and restarting other processes.
Cellcli -> storage cell, to run storage commands
Cellsrv ->storage cell. It receives and unpacks iDB messages transmitted over the InfiniBand interconnect and examines metadata contained in the messages
Diskmon -> compute node, In Exadata, the diskmon is responsible for:,Handling of storage cell failures and I/O fencing
,Monitoring of Exadata Server state on all storage cells in the cluster (heartbeat),Broadcasting intra database IORM (I/O Resource Manager) plans from databases to storage cells,Monitoring or the control messages from database and ASM instances to storage cells ,Communicating with other diskmons in the cluster.
The
following strategy should be used for applying patches in Exadata:
Review the patch README file (know what you
are doing)
Run Exachk utility before the patch application (check the system , know current the situation of the system)
Automate the patch application process (automate it for being fast and to minimize problems)
Apply the patch
Run Exachk utility again -- after the patch application
Verify the patch ( Does it fix the problem or does it supply the related stuff)
Check the performance of the system(are there any abnormal performance decrease)
Test the failback procedure (as you may need to fail back in Production, who knows)

Exadata Database Server Patch (compute
nodes):
This the patch that we are used to work
as an Oracle DBA. These patches are being released specifically for Exadata, so
you should not upgrade one Database to a version that is not support to the
Exadata, so always check in the documentation if the release that you want was
already published. The software to patches already contain upgrades for the
Oracle Database and Oracle Clusterware.
All the patches provided as a bundle
patches are comulative, and it also may include the most recent Patch Set
Update (PSU) and/or Critical Patch Update (CPU).
a) So, for example, if you are in the
11.2.0.2.0 BP 1 (Bundle Patch 1) and would like to migrate to BP 7 (Bundle
Patch 7), you just need to upgrade directly, without applying the 2, 3, 4, 5
and 6.
b) As the Bundle Patches have the last
PSU and CPU, its not necessary to apply PSU/CPU in the Exadata environment,
because its already included in the Bundle Patches. Always check the README
file in order to check which PSU/CPU is included or not in the Bundle Patch.
– Bundle Patches Bug List:
11.2.0.2 Patch Bundles for Oracle
Exadata Database Machine (Doc ID. 1314319.1)
11.2.0.1 Patch Bundles for Oracle Exadata
Database Machine (Doc ID. 1316026.1)
When you need to
apply a bundle patch to Oracle Homes in Exadata, you will need to use
oplan utility.
oplan utility
generates instructions for applying patches, as well as instructions for
rollback. It generates instructions for all the nodes in the cluster. Note
that, oplan does not support DataGuard .. Oplan is supported since release 11.2.0.2 . It
basically eases the patching process, because without it you need to read
Readme files and extract your instructions yourself..
It is used as follows;
as Oracle software
owner,(Grid or RDBMS) execute oplan;
$ORACLE_HOME/oplan/oplan generateApplySteps <bundle patch
location>
it will create you
patch instructions in html and txt formats;
$ORACLE_HOME/cfgtoollogs/oplan/<TimeStamp>/InstallInstructions.html
$ORACLE_HOME/cfgtoollogs/oplan/<TimeStamp>/InstallInstructions.txt
$ORACLE_HOME/cfgtoollogs/oplan/<TimeStamp>/InstallInstructions.txt
Then, choose the
apply strategy according to your needs and follow the patching instructions to
apply the patch to the target.
That 's it..
If you want to
rollback the patch;
execute the
following;(replacing bundle patch location)
$ORACLE_HOME/oplan/oplan generateRollbackSteps <bundle
patch location>
Again,
choose the rollback strategy according to your needs and follow the
patching instructions to rollback the patch from target.
##### Exadata Patching - DB Node Update
Copy the the dbnodeupdate.sh Utility and patch patch 16432033 from szur0023pap
to the new folders. The required patches are stored there.
Alternatively download from MOS and
transfer to the nodes
# scp
username@szur0023pap:/sbclocal/san/DBaaS/Exadata/dbnodeupdate.zip
/u01/patches/system/dbnodeupdate
# scp
username@szur0023pap:/sbclocal/san/DBaaS/Exadata/16784347/Infrastructure/ExadataStorageServer/11.2.3.2.1/p16432033_112321_Linux-x86-64.zip
/u01/patches/system/16432033
Unpack the dbnodeupdate.sh utility
# unzip dbnodeupdate.zip
Make sure you have the latest version of
dbnodupdate.sh. If you don't, then stop here and get the latest version from
MOS by following the above link!
# cd /u01/patches/system/dbnodeupdate
# ./dbnodeupdate.sh -V
dbnodeupdate.sh, version 2.17
Do not unpack patch 16432033
# cd /u01/patches/system/16432033
# ls -l
-rw-r--r-- 1 root root 1216696525 Jun 27
08:33 p16432033_112321_Linux-x86-64.zip
Before you start patching the node,
verify the status of the cluster resources as follows:
# /u01/app/11.2.0.3/grid/bin/crsctl stat
res -t
Check the current image version running
on the node
# imageinfo
Run the dbnodeupdate.sh script in
check/verify mode, using the zip file as the "repository".
# cd /u01/patches/system/dbnodeupdate
# ./dbnodeupdate.sh -u -v -l
/u01/patches/system/16432033/p16432033_112321_Linux-x86-64.zip
The recommended procedure to update a DB
noe is to use the DB Node Update Utility (aka dbnodeupdate.sh), as documented
in Exadata Database Server Patching using the DB Node Update Utility (Doc ID
1553103.1).
If there are no errors in the above
preparartion and verification step, proceed to the actual upgrading. This will
perform a backup using the dbserver_backup.sh script, followed by patching the
system.
# cd /u01/patches/system/dbnodeupdate
# ./dbnodeupdate.sh -u -s -l
/u01/patches/system/16432033/p16432033_112321_Linux-x86-64.zip
Now the system will reboot
Note the last statement of the previous
command, just before the reboot. Once the system is back, this last step will
be executed.
# cd /u01/patches/system/dbnodeupdate/
# ./dbnodeupdate.sh -c
Patching is now completed,
congratulations!
You can now check the image version and
the status of the cluster
# imageinfo
# /u01/app/11.2.0.3/grid/bin/crsctl stat
res -t
Exadata Patching - Compute
Node
Patching on Database server can be performed serially or
in parallel using DCLI utility.
dbnodeupdate.sh utility is used to
perform the database server patching
What dbnodeupdate.sh utility does?
·
Stop/unlock/disable CRS for host
restart
·
Perform LVM snapshot backup of /

HOW
ROLLING PATCH WORKS:
Since version 11.2.1.3.1, Oracle have
introduced the feature “Cell Rolling Apply” in order to simplify the install
and of course, to reduce downtime. You must be aware about that sometimes is
necessary some patches in the compute nodes BEFORE using -rolling option in the
cells nodes.
Below is a brief overview in how it
works:
Preparation of the cell node X
Loop
Turn all Grid Disks offline in the cell
node X
Patch cell node X
Grid Disks online
End Loop
The Storage Server Patch is responsible
for keeping our cell nodes always up-to-date, fixing possibles problems and
this patch includes different component patches, like kernel patches, firmware,
operation system, etc… for the Storage Server.
These patches are usually lunched from
any Database Server (typically using the compute node 1) using dcli and ssh to
remotely patch each cell node.
All the Storage Server patch came with
what the Oracle calls as “Database Minimal Pack” or “Database Convenience
Pack”. These packs are included in a .zip file inside the storage patch
software and must be applied in all the Database Servers (compute nodes),
because it includes, as in the storage patch, kernel, firmware, and operation
system patches necessary.
Applying these patches in the Storage
Server, will also change the Linux version for each server, but for the
Database Minimal Pack, it will NOT change the linux version.
SOME USEFUL COMMANDS:
— Rolling Patch Example
./patchmgr -cells <cells group>
-patch_check_prereq -rolling
./patchmgr -cells <cells group>
-patch -rolling
– Non-Rolling Patch Example
./patchmgr -cells <cells group>
-patch_check_prereq
./patchmgr -cells <cells group>
-patch
– Information about the versions in the
kernel.
– run in the database server, also the
status of the patch.
imageinfo
– Logs to check
/var/log/cellos/validations.log
/var/log/cellos/vldrun*.log
– File with all the cell nodes names,
used in the <cells group> tag
cat

Cell
Node patching :
Exadata Storage Server Patching - Some
details
Exadata Storage Server Patching
●● Exadata Storage Server patch is
applied to all cell nodes.
●● Patching is launched from compute
node 1 and will use dcli/ssh to remotely patch each cell node.
●● Exadata Storage Server Patch zip also
contains Database Minimal Pack or Database Convenience Pack, which are applied
to all compute nodes.
This patch is copied to each compute
node and run locally.
●● Applying the storage software on the
cell nodes will also change the Linux version and applying the database minimal
pack
on the compute nodes does NOT change the
Linux version
To upgrade the Linux on Compute Node
follow MOS Note: 1284070.1
Non rolling patch apply is much faster
as you are applying the patch on all the cell nodes simultaneously, also there
are NO risk to single disk failure. Please
note, this would require full outage.
In case of rolling patch apply, database
downtime is not required, but patch application time is very high. Major risk:
ASM high redundancy to reduce disk
failure exposure
Grid disks offline >>> Patch
Cel01 >>> Grid disks online
Grid disks offline >>> Patch
Cel02 >>> Grid disks online
Grid disks offline >>> Patch
Cel..n>>> Grid disks online
Rolling Patch application can be risky
affair, please be appraised of the followings:
Do not use -rolling option to patchmgr
for rolling update or rollback without first applying required fixes on
database hosts
./patchmgr -cells cell_group
-patch_check_prereq -rolling >>> Make sure this is successful and
review spool carefully.
./patchmgr -cells cell_group -patch
–rolling
Non-rolling Patching Command:
./patchmgr -cells cell_group
-patch_check_prereq
./patchmgr -cells cell_group -patch
How to Verify Cell Node is Patched
Successfully
# imageinfo
Output of this command gives some good
information, including Kernel Minor Version.
Active Image Version:
11.2.2.3.1.110429.1
Active Image Status: Success
If you get anything in "Active
Image Status" except success, then you need to look at validations.log and
vldrun*.log.
The image status is marked as failure
when there is a failure reported in one or more validations.
Check the
/var/log/cellos/validations.log and /var/log/cellos/vldrun*.log files for any
failures.
If a specific validation failed, then
the log will indicate where to look for the additional logs for that validation.
Exadata
Patching - Cell Server
Cell storage patching can be done by
patchmgr utility which is used to do a patching in rolling as
well in
non-rolling fashion.
Syntax: ./patchmgr
-cells cell_group -patch [-rolling] [-ignore_alerts] [- smtp_from
"addr" -smtp_to "addr1 addr2 addr3 ..."]
Here
addr is the sending mail id which is used to send status of patching and
addr1,addr2,addr3 are receiving mail id to receive the status of patching.
Step-1 First
note down the current image version of cell by executing
#imageinfo
Step-2 Go to cell patch directory where patch has been copied
/19625719/Infrastructure/11.2.3.3.1/ExadataStorageServer_InfiniBandSwitch/patch_11.2.3.3.1.140708
Step-3 Reset the server to a known state using the following command
./patchmgr -cells cell_group -reset_force
Step-4 Clean up any
previous patchmgr utility runs using the following command
./patchmgr -cells cell_group -cleanup
Step-5 Verify
that the cells meet prerequisite checks using the following command
(Rolling)
./patchmgr -cells ~/cellgroup -patch_check_prereq -rolling
or
(Non-rolling)
./patchmgr -cells ~/cellgroup -patch_check_prereq
Here cellgroup file contains IPs of all cell server.
Step-6 Output
should not have any error, If any error than resolve it first than re-execute
above command
Step-7 Patch cell server
(Rolling)
./patchmgr -cells ~/cellgroup -patch -rolling
or
(Non-rolling)
./patchmgr -cells ~/cellgroup -patch
Step-8 Check logs if any error in patchmgr.stdout file.
How it works?
Entire patching activity done by patchmgr utility automatically.
·
To ensure good backup exists, USB
recovery media is recreated
·
Check cells have ssh equivalence for
root user
·
Initialize files, check space and
state of cell services
·
Copy, extract prerequisite check
archive to cells
·
Check prerequisites on cell
·
Copy the patch to cell
·
Execute plug-in check for Patch Check
Prereq
·
Initiate patch on cell
·
Reboot the cell
·
Execute plug-in check for Patching
·
Finalize patch
·
Reboot the cell
·
Check the state of patch
·
Execute plug-in check for Post Patch
·
Done
After completion of patching you can check the image
version, it should be changed to new version
#imageinfo
#imagehistory
Rollback
#imageinfo
#imagehistory
Rollback
Step-1 Disable writeback flash cache (You can refer Oracle DOC ID - 1500257.1)
Step-2 Check rollback pre-requisites
(Rolling)
./patchmgr -cells ~/cellgroup -rollback_check_prereq -rolling -ignore_alerts
or
(non-rolling)
./patchmgr -cells ~/cellgroup -rollback_check_prereq -ignore_alerts
Step-3 Perform the rollback
(Rolling)
./patchmgr -cells ~/cellgroup -rollback -rolling -ignore_alerts
or
(Non-Rolling)
./patchmgr -cells ~/cellgroup -rollback -ignore_alerts
Step-4 Clean up the cells using the -cleanup option to clean up
all the temporary patch or rollback files on the cells
./patchmgr -cells ~/cellgroup -cleanup

Most of Exadata Machines have 2 leafs of
Infiniband switches and 1 spine. The position of the 2 Leafs is usually in U20
and U24 and the Spine is located in the very bottom position, U1. Actually,
there are some Exadata Machines that have the Spine switch in the Half or
Quarter Rack, but usually only the Full rack should have it.
In order to patch the switches, you must
apply the patch in the SPINE switch first, rebooting and waiting it to back
online BEFORE proceeding to the next switches (leafs).
All the Infiniband Switchs Patch are not
CUMULATIVE, its necessary to upgrade version by version, for example, if I want
to migrate the version 1.0.1-1 to 1.3.3-2, I must first upgrade 1.0.1-1 to
1.1.3-2 and after 1.1.3-2 to 1.3.3-2.
Exadata
Patching - Infiniband Switch
Here we have listed down bullet points to patch IB
switches on Exadata Database Machine.
Syntax: #patchmgr
-ibswitches [ibswitch_list_file] <-upgrade | -downgrade [-ibswitch_precheck]
[-force]]
Here
ibswitch_list_file contains IP of all the IB switches
Upgrade - to upgrade the switch
Downgrade - to downgrade the switch
ibswitch_precheck - to check the prerequisites
Patchmgr utility would be available in storage server patch directory.
Patching
#./patchmgr -ibswitches ibswitches -upgrade -ibswitch_precheck
How it works?
·
Disable Subnet Manager
·
Copy firmware to switch
·
Check minimal firmware version to
upgrade it
·
Verify enough space in /tmp and /
·
Verify for free memory to start
upgrade
·
Verify host details in /etc/hosts and
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
·
Verify for NTP server
·
Pre-upgrade validation
·
Start upgrade
·
Load firmware
·
Disable Subnet Manager
·
Verify that /conf/configvalid is set
to 1
·
Set SMPriority to 5
·
Reboot switch
·
Restart Subnet Manager
·
Start post-update validation
·
Confirmation: Inifiniband switch is
at target patching level
·
Verifying host details in /etc/hosts
and /etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
·
Verifying NTP Server
·
Firmware verification on InfiniBand
switch
·
Post-check validation on
IBSwitch
·
Final Confirmation: Update switch to
2.1.3_4 (Firmware version)
Once it completes on one switch, it will start to upgrade next available switch and in last it will give overall status of upgrade.

Applying patch
to Exadata
Box
Hi
everyone! I’m here to post about the patch apply on Exadata Machine. As best
practices we will apply the QFSP (Quatterly Full Stack Patch) for Exadata
Jan/2014. The patch apply is totally automatic so if the prereqs were addressed
correctly, you will have no bad surprise and your Exadata environment will be
patched successfully. At my job, our team applied it recently without any
issue.
The patch
number is 17816100 [Quarterly Full Stack Download Patch For Oracle Exadata (Jan
2014 - 11.2.3.3.0)] which has 3.6G . This patch will patch most of the Exadata
Database Machine components, whic are: databases; dbnodes; storage servers;
infiniband switches; and PDUs (Power Distribution Units). Our databases are
already patched to version (11.2.0.3.21) and on the end of this patching, the
image version for the db and cell nodes should be 11.2.3.3.0 as we are moving
from image 11.2.3.2.1.
You should
carefully read all the README and notes regarding this patch as there is a
complete list of prereqs and things to analyze. Although the db and cell nodes
will all end with the same image version, on our case, the infiniband switches
upgrade was optional according to the compatibility matrix but to keep things
easy, we upgraded them too. The PDUs upgrade are optional and these is the easiest
one.
Now lets
get hands on it and lets begin with the PDUs. Doing this upgrade will cost you
no outage and it is as simple as upgrading the firmware from your home network
router. Just navigate to your PDU from your browser and hit “Net Configuration”.
Scroll down to “Firmware Upgrade” and select the file MKAPP_Vx.x.dl to upgrade.
After the PDU firmware was upgraded it will popup for the HTML interface to be
upgraded so you need to select the file HTML_Vx.x.dl. Do that on all of the
PDUs and your are done with it. Peace of cake.
Now lets
proceed to the cells upgrade. As we usage the rolling upgrade strategy (no
outage), all of the database software must have 17854520 patch applied on them,
other while, the DBs may hang or crash. The utility used to patch the cells and
infiniband switches is patchmgr (which should be executed as root). Also, you
can run a precheck for the upgrade from this utility, as mentioned below:
#
./patchmgr -cells cell_group -patch_check_prereq -rolling
It is
recommended to higher the disk repair time from diskgroups, in order to do not
drop the disks. Also, and according to Oracle docs, it is recommended to reset
the cells if this is the first time that those cells image are upgraded. Do
this one cell at a time and then initiate the cell upgrade. The patchmgr should
be executed from the dbnode.
#
./patchmgr -cells cel01 -reset_force
# ./patchmgr -cells cel02 -reset_force
# ./patchmgr -cells cel03 -reset_force
# ./patchmgr -cells cell_group -rolling
# ./patchmgr -cells cel02 -reset_force
# ./patchmgr -cells cel03 -reset_force
# ./patchmgr -cells cell_group -rolling
After
finishing successfully the cells upgrade, go for infiniband switches precheck
upgrade and execute the patchmgr utility as listed below:
#
./patchmgr -ibswitches -upgrade -ibswitch_precheck
To
continue with the ib switches upgrade just remove the precheck parameter:
#
./patchmgr -ibswitches -upgrade
When you are done with the infiniband switches and the cell nodes
you should go to upgrade the database nodes. For this upgrade, you will have
the dbnodeupdate.sh utility. This will upgrade dbnodes
kernel and all of the dependent packages. Pay attention that if you have any
other third package installed you should upgrade it manually after the upgrade.
On our environment, the kernel will be upgrade to Oracle Linux 5.9
(kernel-2.6.39-400.126.1.el5uek).The dbnodeupdate.sh is fully automatic and it will disable
and bring down the CRS for the node. You must use root user to run it and for
best practices do it one node at a time.
To perform a precheck run it with the parameter -v on the end
# ./dbnodeupdate.sh -u -l $PATCH_17816100/Infrastructure/ExadataStorageServer/11.2.3.3.0/p17809253_112330_Linux-x86-64.zip -v
# ./dbnodeupdate.sh -u -l $PATCH_17816100/Infrastructure/ExadataStorageServer/11.2.3.3.0/p17809253_112330_Linux-x86-64.zip -v
Now to start the upgrade for the dbnode, execute it without the -v
parameter
# ./dbnodeupdate.sh -u -l $PATCH_17816100/Infrastructure/ExadataStorageServer/11.2.3.3.0/p17809253_112330_Linux-x86-64.zip
# ./dbnodeupdate.sh -u -l $PATCH_17816100/Infrastructure/ExadataStorageServer/11.2.3.3.0/p17809253_112330_Linux-x86-64.zip
After the machine reboots, confirm the upgrade executing:
# ./dbnodeupdate.sh -c
# ./dbnodeupdate.sh -c
Perform
this steps on all the dbnodes remaining and you are done. The whole Exadata
Machine is patched, run imageinfo on all dbnodes e storage servers to confirm
the new image. On the ibswitches run the command version to confirm it:
# dcli -g
all_group -l root imageinfo

Upgrading
Exadata to 11.2.0.3 and Applying BP14
Upgrading Exadata to 11.2.0.3 and
Applying Bundle Patch 14
In this blog, I'll
walk you through the abbreviated steps to apply Bundle Patch 14 on our Exadata
X2-2 Quarter Rack. I say "abbreviated" because I'm simply going
to bullet all the steps - this is no substitute for reading the various README
files.
For BP14, I'm going
to apply all patches in a rolling upgrade fashion. The nodes in our
Exadata are:
- cm01dbm01
(Compute node 1)
- cm01dbm02
(Compute node 2)
- cm01cel01 (Cell
1)
- cm01cel02 (Cell
2)
- cm01cel03 (Cell
3)
Preparation
1) Downloaded
p13551280_112030_Linux-x86-64.zip from MOS
2) Transferred
p13551280_112030_Linux-x86-64.zip to our first compute node, cm01dbm01
3) Unzipped
p13551280_112030_Linux-x86-64.zip
4) Read the various
README.txt files
5) Login to each
storage server, compute node, Infiniband switch, and validate the current
versions using "imageinfo"
Patch Contents
Bundle Patch 14
(13551280) contains the latest software versions for the entire Exadata
techology stack. The patch contents are split into 3 sections:
* Infrastructure
- Includes patches
for Exadata Storage Server nodes, version 11.2.2.4.2
- InfiniBand
switches, version 1.3.3-2
- PDUs, firmware
version 1.04
* Database
- Oracle RDBMS
11.2.0.3
- Grid
Infrastructure , 11.2.0.3
- OPatch 11.2.0.1.9
- OPlan 11.2.0.2.7
* Systems
Management
- EM Agent,
11.1.0.1.0
- EM Plugins for
InfiniBand Switches, Cisco switches, PDUs, KVMs, ILOMs
- OMS patches for
any/all OMS homes monitoring Exadata targets (11.1.0.1.0)
Patching Storage Servers
1) Transfer
13551280/Infrastructure/ExadataStorageServer/11.2.2.4.2 contents to storage
cell cm01cel01:/tmp, our first cell and unzip the zip file
2) Read MOS note
1388400.1 and do the following:
- "# cellcli
-e list griddisk where diskType=FlashDisk". Make sure we don't have
any Flash Grid disks, which we didn't.
- "# cellcli
-e list physicaldisk attributes name, status, slotNumber". Make sure
no duplicate disks exists with the same slot number. In our case, we
didn't have any.
- "# cellcli
-e list physicaldisk". Make sure they're all normal.
- "# grep -in
'Failed to parse the command' $CELLTRACE/ms-odl.trc*". Make sure we
don't have any flash disk population errors. We didn't.
- Since our current
cell version image is > 11.2.2.2.x, we skipped steps 3a and 3b.
- Transfer
validatePhysicalDisks from MOS note to /tmp and run it. It should look like
this:
[root@cm01cel01
patch_11.2.2.4.2.111221]# /tmp/validatePhysicalDisks
[SUCCESS] CellCLI
output and MegaCLI output are consistent.
[root@cm01cel01
patch_11.2.2.4.2.111221]#
- Ensure database
tier hosts are > 11.2.0.1 to support rolling upgrades. In our case,
they are.
3) Validate that
all physical disks have valid physicalInsertTime:
[root@cm01cel01
patch_11.2.2.4.2.111221]# cellcli -e 'list physicaldisk attributes luns
where physicalInsertTime = null'
[root@cm01cel01
patch_11.2.2.4.2.111221]#
4) Verify that no
duplicate slotNumbers exist. This was done per MOS note 1388400.1, step 2
5) Obtain LO and
serial console access for cell
- Login to
cm01cel01-ilom as root
- Type "start
/SP/console"
- Login to console
as root
6) Check version of
ofa by doing "rpm -qa|grep ofa". Ours was higher than the
minimum version, so we're OK
7) Since we're
doing in rolling fashion, ensure the Grid Disk are all offline:
[root@cm01cel01 ~]#
cellcli -e "LIST GRIDDISK ATTRIBUTES name WHERE
asmdeactivationoutcome != 'Yes'"
[root@cm01cel01
~]#
[root@cm01cel01 ~]#
cellcli -e "ALTER GRIDDISK ALL INACTIVE"

8) Shutdown cell
services
[root@cm01cel01 ~]#

[root@cm01cel01 ~]#

[root@cm01cel01 ~]#
shutdown -F -r now
Broadcast message

9) Since we're
doing this in rolling fashion, activate all disks and check grid disk
attributes. I'm wondering if steps 7 and 8 were actually required, but I
believe they were to ensure we had a healthy disk status:
[root@cm01cel01 ~]#
cellcli -e 'list griddisk attributes name,asmmodestatus'
DATA_CD_00_cm01cel01
OFFLINE
DATA_CD_01_cm01cel01
OFFLINE
DATA_CD_02_cm01cel01
OFFLINE
(wait)
[root@cm01cel01 ~]#
cellcli -e 'list griddisk attributes name,asmmodestatus' \
> |grep -v
ONLINE
[root@cm01cel01
~]#
10) Ensure network
configuration is consistent with cell.conf by running
"/opt/oracle.cellos/ipconf -verify"
[root@cm01cel01 ~]#
/opt/oracle.cellos/ipconf -verify
Verifying of
Exadata configuration file /opt/oracle.cellos/cell.conf
Done. Configuration
file /opt/oracle.cellos/cell.conf passed all verification checks
[root@cm01cel01
~]#
11) Prep for
patchmgr - ensure that root has user equivalence by running dcli commands
below:
[root@cm01cel01 ~]#
dcli -g cell_group -l root 'hostname -i'
cm01cel01:
172.16.1.12
cm01cel02:
172.16.1.13
cm01cel03:
172.16.1.14
[root@cm01cel01
~]#
12) Check
pre-requisites by running "./patchmgr -cells ~/cell_group
-patch_check_prereq -rolling" from patch stage location:
[root@cm01cel01
patch_11.2.2.4.2.111221]# ./patchmgr -cells ~/cell_group \
>
-patch_check_prereq -rolling
[NOTICE] You will
need to patch this cell by starting patchmgr from some other cell or database

you're not using the LO or serial console - stay logged into the LO console to
monitor things in case things go wrong:
[root@cm01cel01 ~]#
echo $consoletype
pty
[root@cm01cel01
~]#
15) Apply the patch
in rolling fashion - note that this will patch cm01cel02 and cm01cel03, since
I'm launching it from cm01cel01. After it's done, we'll have to patch
cm01cel01. I should have launched this from a compute node, for some
reason I always forget =)
[root@cm01cel01
patch_11.2.2.4.2.111221]# ./patchmgr -cells ~/cell_group -patch -rolling
NOTE Cells will
reboot during the patch or rollback process.
NOTE For
non-rolling patch or rollback, ensure all ASM instances using

18) Check
/var/log/cellos/validations.log on both cm01cel02 and cm01cel03
19) From cm01dbm01
(first compute node), un-staged the Infrastructure patch in
/tmp/patch_11.2.2.4.2.111221
20) Create
cell_group file containing only "cm01cel01"
21) Check
user-equivalence by doing below:
[root@cm01dbm01
patch_11.2.2.4.2.111221]# dcli -g cell_group -l root 'hostname -i'
cm01cel01:

"./patchmgr -cells cell_group -patch_check_prereq -rolling"
23) Patch cm01cel01
by doing "./patchmgr -cells cell_group -patch -rolling":
[root@cm01dbm01

25) Check imageinfo
and /var/log/cellos/validations.log on cm01cel01
26) Cleanup using
"./patchmgr -cells cell_group -cleanup" (from cm01dbm01 - it will
cleanup on all 3 cells)
27) Login to
cm01cel01 to check InfiniBand. As a side-note, we should have patched IBs
first according to something very far down in the README, but luckily our IB
versions are in good shape:

28) Apply the
minimal pack to database tier hosts (Section 6 of the README.txt). Start
by starting an LO console by SSH-ing into cm01dbm01-ilom and doing "start
/SP/console"
28) Check
imagehistory by running "# imagehistory". We're in good shape,
since we recently applied BP 13
29) Stop dbconsole
for each database on cm01dbm01 (and cm01dbm02)
30) Stop cluster
using /u01/app/11.2.0/grid/bin/crsctl stop cluster -f -all
31) Stop OSW by
running "/opt/oracle.oswatcher/osw/stopOSW.sh"
32) Set memory
settings in /etc/security/limits.conf. On this step, since we'd setup
hugepages, the previous values calculated by "let -i x=($((`cat
/proc/meminfo | grep 'MemTotal:' | awk '{print $2}'` * 3 / 4))); echo $x"
are commented out, and this is OK.
33) SCP
db_patch_11.2.2.4.2.111221.zip from /tmp/patch_11.2.2.4.2.111221 to /tmp on
cm01dbm01 and cm01dbm02. When we apply these patches, we'll be applying
from an SSH session on each Database tier host
34) Unzip
/tmp/db_patch_11.2.2.4.2.111221.zip and go to /tmp/db_patch_11.2.2.4.2.111221
directory
35) Run
"./install.sh -force" on cm01dbm02. This will take a little
while ...
36) While this is
running, repeat above on cm01dbm01
37) On cm01dbm02
(first node patched), check imageinfo. It should look like below:
[root@cm01dbm02 ~]#
/usr/local/bin/imageinfo
Kernel version:
2.6.18-238.12.2.0.2.el5 #1 SMP Tue Jun 28 05:21:19 EDT 2011 x86_64

38) Verify the ofa
rpm by running "rpm -qa | grep ofa", comparing against kernel
version. It should look like this:
[root@cm01dbm02 ~]#
rpm -qa | grep ofa
ofa-2.6.18-238.12.2.0.2.el5-1.5.1-4.0.53

39) Verify the
controller cache is on using "/opt/MegaRAID/MegaCli/MegaCli64 -LDInfo
-Lall -a0". You should see this:
Default Cache
Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU
Current Cache
Policy: WriteBack, ReadAheadNone, Direct, No Write Cache if Bad BBU
40) Run
"/opt/MegaRAID/MegaCli/MegaCli64 -AdpAllInfo -aAll | grep 'FW Package
Build'" and ensure is says "FW Package Build: 12.12.0-0048"
41) Reboot the
server (cm01dbm02) after running "crsctl stop crs"
42) Repeat steps
37-41 on cm01dbm01 when it's back up
Patching InfiniBand Switches
1) Login to
cm01sw-ib2 as root
2) Check the
version of the software - on our switches, we're already at 1.3.3.2 so we
didn't actually need to do anything:
[root@cm01sw-ib2
~]# version

3) Validate on
cm01sw-ib3
Patching PDUs
1) Go to 13551280/Infrastructure/SunRackIIPDUMeteringUnitFirmware/1.04
and unzip the zip file
2) Transfer the *DL
files to laptop
3) Login to PDUA
(http://cm01-pdua.centroid.com/, in our case)
4) Click on Network
Configuration and login as dmin
5) Go down to Firmware
Upgrade and Choose MKAPP_V1.0.4.DL and click Submit
6) When done,
update the HTML DL file. It seems to "hang" for a very long
time, but eventually ...
7) Repeat on
cm01-pdub.centroid.com
Upgrade GI Home and RDBMS Home from
11.2.0.2 to 11.2.0.3
Prior to patching
the latest BP14 updates to 11.2.0.3, we need to get our GI and RDBMS Homes
updated to 11.2.0.3 by following MOS note 1373255.1. There are a couple
of sections of steps required:
- Prepare
environments
- Install and
Upgrade GI to 11.2.0.3
- Install 11.2.0.3
database software
- Upgrade databases
to 11.2.0.3. In our case, this includes dwprd, dwprod, and visx cluster
database
- Do some post
upgrade steps
1) Download
11.2.0.3 from https://updates.oracle.com/ARULink/PatchDetails/process_form?patch_num=10404530
and transfer to /u01/stg on cm01dbm01.
2) Since we're
already at BP13, we don't need to apply 12539000
3) Run Exachk to
validate that the cluster is ready to patch. MOS Document 1070954.1
contains details. Download exachk_213_bundle.zip, unzip it, and run:
[oracle@cm01dbm01
~]$ cd /u01/stg/exachk/
[oracle@cm01dbm01
exachk]$ ls
collections.dat
exachk_213_bundle.zip
exachk_dbm_121311_115203-public.html ExachkUserGuide.pdf readme.txt
UserGuide.txt
exachk ExachkBestPracticeChecks.xls
Exachk_Tool_How_To.pdf exachk.zip rules.dat
[oracle@cm01dbm01
exachk]$ ./exachk
Our Exachk run
showed a couple of issues, and we fixed the following:
- Set processes
initialization parameter to 200 for both ASM instances
- Set
cluster_interconnects to appropriate interface for dwprd and dwprod1
- Cleaned up audit
dest files and trace/trm file for ASM instances, both nodes
- Set
filesystemio_options=setall on all instances
- When done,
bounced cluster using "crsctl stop cluster -f -all", followed by
"crsctl start cluster -all"
4) Validate
readiness of CRS by running cluvfy. Go to <stage>/grid, login as grid,
and run this:
[grid@cm01dbm01
grid]$ ./runcluvfy.sh stage -pre crsinst -upgrade \
> -src_crshome
/u01/app/11.2.0/grid \
> -dest_crshome
/u01/app/11.2.0.3/grid \
> -dest_version
11.2.0.3.0 \
> -n
cm01dbm01,cm01dbm02 \
> -rolling \
> -fixup
-fixupdir /home/grid/fixit
- Failed on kernel
parameters because grid didn't have access to /etc/sysctl.conf. Ignore
it.
- Failed on bondeth0
and some VIP stuff - ignore it. I think this is a cluvfy bug
5) Create new GI
Homes for 11.2.0.3. Example below from cm01dbm01, but do this on both
nodes:
[root@cm01dbm01 ~]#
mkdir -p /u01/app/11.2.0.3/grid/
[root@cm01dbm01 ~]#
chown grid /u01/app/11.2.0.3/grid
[root@cm01dbm01 ~]#
chgrp -R oinstall /u01/app/11.2.0.3
[root@cm01dbm01
~]#
6) Unzip all the
10404530 software
7) No need to
update OPatch software - I didn't this with the BP14 stuff from patch 13513783
(see next section)
8) Disable AMM in
favor of ASMM for ASM instance. Follow the steps in the 1373255.1 document.
In our case, our SPFILE is actually a data file in $GI_HOME/dbs/DBFS_DG
instead of the ASM disk group - I'm thinking about moving it with spmove and
asmcmd, but I think I'll hold off for now. When done it should look like
below for both instances:
SQL> select
instance_name from v$instance;
INSTANCE_NAME
----------------
+ASM2
SQL> show sga
Total System Global
Area 1319473152 bytes
Fixed Size
2226232 bytes
Variable Size 1283692488
bytes
ASM Cache
33554432 bytes
SQL>
9) Bounce databases
and ASM and validate __shared_pool_size and __large_pool_size, along with
values changed above. Again, refer to the output above
10) Validate
cluster interconnects. This is how it shoud look - they need to be
manually set:
SQL> select
inst_id, name, ip_address from gv$cluster_interconnects
2 /
INST_ID NAME
IP_ADDRESS
----------
--------------- ----------------
2 bondib0
192.168.10.2
1 bondib0
192.168.10.1
SQL> create
pfile='/tmp/asm.ora' from spfile;
File created.
SQL> !cat
/tmp/asm.ora|grep inter
*.cluster_interconnects='192.168.10.1'
+ASM1.cluster_interconnects='192.168.10.1'
+ASM2.cluster_interconnects='192.168.10.2'
SQL>
11) Shutdown visx,
dwprd, and dwprod databases. I'm going to shutdown everything for now for
simplicity's sake
12) Login as
"grid" to cm01dbm01 and unset ORACLE_HOME, ORACLE_BASE, and
ORACLE_SID. Get a VNC session established to we can launch the installer.
Run "./runInstaller" and follow the instructions on 1373255.1.
It will fail on VIP, Node connectivity, and patch 12539000 but I'm
crossing my fingers and assuming this is a bug.
(insert deep breath
...)
Things did
install/upgrade fine, it took about 45 minutes. The post-install CVU step
failed with the same errors are the pre-CVU stage (network/VIP stuff), but this
is OK.
13) Stop CRS on
both nodes
14) Relink GI
oracle executable with RDS
[grid@cm01dbm01 ~]$
dcli -g ./dbs_group ORACLE_HOME=/u01/app/11.2.0.3/grid \
> make -C
/u01/app/11.2.0.3/grid/rdbms/lib -f ins_rdbms.mk \
> ipc_rds
ioracle
15) Start CRS on
both nodes
16) Login as oracle
on cm01dbm01 and start a VNC session. At this point, the 11.2.0.3
software has already been installed.
17) Unset
ORACLE_HOME, ORACLE_BASE, and ORACLE_SID, and launch runInstaller. The
pre-req checks will fail on subnet and VIP details, as above - choose to
ignore.
18) When
installation completes, link oracle with RDS:
dcli -l oracle -g
~/dbs_group ORACLE_HOME=/u01/app/oracle/product/11.2.0.3/dbhome_1 \
make -C
/u01/app/oracle/product/11.2.0.3/dbhome_1/rdbms/lib -f ins_rdbms.mk ipc_rds
ioracle
19) Copy OPatch
from 11.2.0.2 directory to 11.2.0.3 directory - at the same time, might has well
do the GI home as "grid". When this is done, we can move on to
the bundle patch
Patching Compute Nodes to 11.2.0.3
BP 14 (13513783)
1) Go to
13551280/Database/11.2.0.3 on first node and unzip
p13513783_112030_Linux-x86-64.zip
2) Extract OPatch
from 13551280/Database/OPatch on both cm01dbm01 and cm01dbm02, RDBMS and GI
Homes. For example:
[root@cm01dbm01
OPatch]# unzip p6880880_112000_Linux-x86-64.zip -d /u01/app/11.2.0/grid/
Archive:
p6880880_112000_Linux-x86-64.zip
replace
/u01/app/11.2.0/grid/OPatch/docs/FAQ? [y]es, [n]o, [A]ll, [N]one,
[r]ename:
3) Make sure
GI/OPatch files are owned by grid:oinstall and RDBMS/OPatch files are owned by
oracle
4) Check inventory
for RDBMS home (both nodes):
[oracle@cm01dbm01
~]$ /u01/app/oracle/product/11.2.0.3/dbhome_1/OPatch/opatch lsinventory -detail
-oh /u01/app/oracle/product/11.2.0.3/dbhome_1/
5) Check inventory
for GI home (both nodes):
[grid@cm01dbm01 ~]$
/u01/app/11.2.0/grid/OPatch/opatch lsinventory -detail -oh
/u01/app/11.2.0/grid/
6) Set permissions
to oracle:oinstall to patch location:
[root@cm01dbm01
11.2.0.3]# chown -R oracle:oinstall 13513783/
[root@cm01dbm01
11.2.0.3]#
7) Check for patch
conflicts in GI home. Login as "grid" and run the below.
You will see some conflicts:
[grid@cm01dbm01 ~]$
/u01/app/11.2.0/grid/OPatch/opatch prereq \
>
CheckConflictAgainstOHWithDetail -phBaseDir
/u01/stg/13551280/Database/11.2.0.3/13513783/13513783/
[grid@cm01dbm01 ~]$
/u01/app/11.2.0/grid/OPatch/opatch prereq \
>
CheckConflictAgainstOHWithDetail -phBaseDir
/u01/stg/13551280/Database/11.2.0.3/13513783/13540563/
[grid@cm01dbm01 ~]$
/u01/app/11.2.0/grid/OPatch/opatch prereq \
>
CheckConflictAgainstOHWithDetail -phBaseDir
/u01/stg/13551280/Database/11.2.0.3/13513783/13513982/
8) Check for patch
conflicts on the RDBMS home, as oracle:
[oracle@cm01dbm01
11.2.0.3]$ /u01/app/oracle/product/11.2.0.3/dbhome_1/OPatch/opatch prereq
CheckConflictAgainstOHWithDetail -phBaseDir ./13513783/13513783/
[oracle@cm01dbm01
11.2.0.3]$ /u01/app/oracle/product/11.2.0.3/dbhome_1/OPatch/opatch prereq
CheckConflictAgainstOHWithDetail -phBaseDir
./13513783/13540563/custom/server/13540563
9) Login as root
and add opatch directory for GI home to path
10) Patch by
running the opatch command below - don't try to patch the GI and RDBMS homes
alone:
[root@cm01dbm01
11.2.0.3]# opatch auto ./13513783/
Executing
/usr/bin/perl /u01/app/11.2.0.3/grid/OPatch/crs/patch112.pl -patchdir . -patchn

opatch auto log
file location is
/u01/app/11.2.0.3/grid/OPatch/crs/../../cfgtoollogs/opatchauto2012-02-13_00-34-53.log

OPatch is
bundled with OCM, Enter the absolute OCM response file path:
/u01/app/oracle/product/11.2.0.3/dbhome_1/OPatch/ocm/bin/ocm.rsp
11) The above
succeeded on the first patch, failed on the second. So I'm going to patch
manually. First, as oracle, ensure ORACLE_HOME is the new 11.2.0.3 home
and run this:
[oracle@cm01dbm01
~]$ srvctl stop home -o $ORACLE_HOME -s /tmp/x.status -n cm01dbm01
12) Unlock crs by
running this:
[root@cm01dbm01
11.2.0.3]# /u01/app/11.2.0.3/grid/crs/install/rootcrs.pl -unlock
Using configuration
parameter file: /u01/app/11.2.0.3/grid/crs/install/crsconfig_params
13) Apply the first
GI patch:
[grid@cm01dbm01 ~]$
/u01/app/11.2.0.3/grid/OPatch/opatch napply -oh /u01/app/11.2.0.3/grid/ -local
/u01/stg/13551280/Database/11.2.0.3/13513783/13540563/
14) Apply second GI
patch:
[grid@cm01dbm01 ~]$
/u01/app/11.2.0.3/grid/OPatch/opatch napply -oh /u01/app/11.2.0.3/grid/ -local
/u01/stg/13551280/Database/11.2.0.3/13513783/13513982/
15) Login as oracle
(database owner) on cm01dbm01 and run pre-script:
[oracle@cm01dbm01
scripts]$ pwd
/u01/stg/13551280/Database/11.2.0.3/13513783/13540563/custom/server/13540563/custom/scripts
[oracle@cm01dbm01
scripts]$ ./prepatch.sh -dbhome /u01/app/oracle/product/11.2.0.3/dbhome_1/
./prepatch.sh completed
successfully.
[oracle@cm01dbm01
scripts]$
16) Apply BP patch
to RDBMS home on cm01dbm01:
[oracle@cm01dbm01
13513783]$ pwd

/u01/app/oracle/product/11.2.0.3/dbhome_1 -local ./13540563/custom/server/13540563
17) Run post DB
script:
[oracle@cm01dbm01
13513783]$ ./13540563/custom/server/13540563/custom/scripts/postpatch.sh
-dbhome /u01/app/oracle/product/11.2.0.3/dbhome_1/
Reading
/u01/app/oracle/product/11.2.0.3/dbhome_1//install/params.ora..
18) Run post
scripts as root:
[root@cm01dbm01
11.2.0.3]# cd /u01/app/oracle/product/11.2.0
[root@cm01dbm01
11.2.0]# cd /u01/app/11.2.0.3/grid/
[root@cm01dbm01
grid]# cd rdbms/install/
[root@cm01dbm01
install]# ./rootadd_rdbms.sh
[root@cm01dbm01
install]# cd ../../crs/installq
[root@cm01dbm01
install]# ./rootcrs.pl -patch
Using configuration
parameter file: ./crsconfig_params
20) Repeat steps
11-18 on cm01dbm02, except in this case we need to first apply the first GI
patch
21) At this point,
we've got GI completely upgraded to 11.2.0.3 and a patched 11.2.0.3 home for
our RDBMS tier, but our databases still live on 11.2.0.2. Let's go on to
the next section
1) Start all
databases on 11.2.0.2 and make sure they're healthy. One thing I screwed
up was on the GI installation, I put in the wrong ASMDBA/ASMOPER/ASMADMIN
accounts. This made it impossible for the database instances to start
after things were patched (on 11.2.0.2). I worked around it by adding
"oracle" to all the "asm" groups (i.e. made its group
membership look like grid). I'll fix this later.
2) Run the upgrade
prep tool for each database (NEW_HOME/rdbms/admin/utlu112i.sql). Note
that this took quite a long time on our Oracle EBS R12 database
3) Set
cluster_interconnects to correct InfiniBand IP. Below is an example from
one of the 3 databases, but they look the same on all:
SQL> select
inst_id, name, ip_address from gv$cluster_interconnects;
INST_ID NAME
IP_ADDRESS
----------
--------------- ----------------
1 bondib0
192.168.10.1
2 bondib0
192.168.10.2
SQL>
4) I don't have any
Data Guard environments or listener_networks setup, so I can skip these
sections from the README.txt
5) Launch dbua from
the 11.2.0.3 home and to upgrade the first database. It complained on a
few underscore parameters and dictionary statistics, but I chose to ignore and
move on.
6) After my first
database was upgraded, I validated things by running "srvctl status
database", checking /etc/oratab, checking V$VERSION, etc.
7) Repeat steps 5
and 6 for the remaining databases.
8) On each database
that was upgraded, a couple of underscore parameter need to be reset - see
below:
SYS @ dwprd1>
alter system set "_lm_rcvr_hang_allow_time"=140 scope=both;
System altered.
Elapsed:
00:00:00.04
SYS @ dwprd1>
alter system set "_kill_diagnostics_timeout"=140 scope=both;
System altered.
Elapsed:
00:00:00.01
SYS @ dwprd1>
alter system set "_file_size_increase_increment"=2143289344
scope=both
2 ;
System altered.
Elapsed:
00:00:00.00
9) Apply Exadata
Bundle Patch. See below:
/u01/app/oracle/product/11.2.0.3/dbhome_1/rdbms/admin
[oracle@cm01dbm01
admin]$ sqlplus / as sysdba

Finishing Up
1) Validate all
your databases, CRS/GI components, etc.
2) Validate all ASM
grid disks, Cell status
3) Cleanup staged
patched from /tmp and/or other locations
4) Cleanup 11.2.0.2
GI and RDBMS Homes and ensure that all initialization parameters are pointing
to the right spots
5) Fix group
membership
good one :)
