Oracle TFA And AHF log collection / Installation

 

Trace File Analyzer Collector also known as TFA is a diagnostic collection utility which greatly simplifies the diagnostic data collection for both Oracle Database as well as Oracle Clusterware/Grid Infrastructure RAC environments.

Trace File Analyzer provides a central and single interface for all diagnostic data collection and analysis.

When a problem occurs, TFA collects all the relevant data at the time of the problem and consolidates data even across multiple nodes in a clustered Oracle RAC environment.  Only the relevant diagnostic data is collected and can be packaged and uploaded to Oracle Support and this leads to faster resolution times. All the required diagnostic data is collected via a single tfactl command instead of having to individually look for the required diagnostic information across a number of database and cluster alert logs, trace files or dump files.

In addition to the core functionality of gathering, consolidating and processing diagnostic data, Trace File Analyzer comes bundled with a number of support tools which enable us to obtain a lot of other useful information like upgrade readiness, health checks for both Engineered as well as non-Engineered systems, OS performance graphs, Top SQL queries etc.

Oracle Trace File Analyzer is shipped along with Oracle Grid Infrastructure (from version 11.2.0.4). However, it is recommended to download the latest TFA version which can be accessed via the My Oracle Support Note 1513912.1 since the TFA bundled with the Oracle Grid Infrastructure does not include many of the new features, bug fixes and more importantly the Oracle Database Support Tools bundle.

Oracle releases new versions of the TFA several times a year and the most current version is Trace File Analyzer 18.1.1 which is now available for download via the MOS Note 1513912.1.

__________________
Install   Tfa 
__________________

Download the latest version of Oracle Trace File Analyzer with Oracle Database support tools bundle from My Oracle Support note 1513912.1

Upgrading is similar to first-time install. As root, use the installTFAplatform script example for linux > 

./installTFA-Linux.

For  Rac :  
Install Tfa on both Nodes  -->  Sync  on both Nodes  --> Start 

( As root ) 
./installTFAplatform 

( As Oracle User ) 
$ ./installTFAplatform -extractto dir -javahome jre_home

cd /u01/software
unzip TFA-LINUX_v18.2.1.zip
mkdir -p $ORACLE_HOME/tfa
./installTFA-LINUX -local -tfabase $ORACLE_HOME/tfa



After having completed this process on all nodes, let’s synchronize them. As I decided not to use SSH, I need to execute those final steps :

Launch tfactl syncnodes using sudo : 
# sudo /grid/infrastructure/home/bin/tfactl syncnodes       ( # $GIHOME/tfa/nodename/tfa_home/bin/synctfanodes.sh ) 

Login using root is disabled in sshd config. Please enable it or
Please copy these files manually to remote node and restart TFA

1. /grid/infrastructure/home/tfa/node01/tfa_home/server.jks
2. /grid/infrastructure/home/tfa/node01/tfa_home/client.jks
3. /grid/infrastructure/home/tfa/node01/tfa_home/internal/ssl.properties

These files must be owned by root and should have 600 permissions.


sudo /grid/infrastructure/home/bin/tfactl stop
sudo /grid/infrastructure/home/bin/tfactl start

##################################################################################
Oracle Autonomous Health Framework (Former TFA)
##################################################################################

Oracle Autonomous Health Framework is a collection of components that analyzes the diagnostic data collected, and proactively identifies issues before they affect the health of your clusters or your Oracle Real Application Clusters (Oracle RAC) databases. Oracle Autonomous Health Framework contains Oracle ORAchk, Oracle EXAchk, and Oracle Trace File Analyzer.

Install Oracle Autonomous Health Framework as root to obtain the fullest capabilities. Oracle Autonomous Health Framework has reduced capabilities when you install it as a non-root user.AFH can be run in two different modes either as daemon or Non-daemon mode. Both are doing same thing but daemon mode is more preferred.

To install Oracle AHF we run the ahf_setup installer with the -extract parameter. We also specify the -notfasetup parameter to avoid enabling the Oracle Trace File Analyser component of Oracle AHF.

For Rac  we need to install on both nodes . AHF will automatically synchronize between nodes.  IF show status  shows both nodes means   its synchronized no need to manually synchronize like tfa  

By default Oracle AHF will be installed to the /opt/oracle.ahf directory.

1) Download latest TFA software DocID 2550798.1
2) copy /u01/src/AHF-LINUX_v20.2.0.zip
3) unzip AHF-LINUX_v20.2.0.zip
4) Install  TFA  
as root 
 cd /u01/src/
 ./ahf_setup
[root@dbhost]# ./ahf_setup -extract -notfasetup 


 as  non root 
./ahf_setup -ahf_loc $ORACLE_HOME/ahf




__________________

upgrade the AHF 

__________________

1  mkdir /tmp/AHF

2  copy the latest AHF to /tmp/AHF and unzip 

4. uninstall existing  TFA : 

tfactl uninstall

3  ./ahf_setup -data_dir /u01/app/grid_base -tmp_loc /u01/app/grid_base/tmp/   ( You can find the data directory " ps -ef  | grep tfa | grep HeapDumpPath" ) 

4) Verify  TFA installed : 

/opt/oracle.ahf/tfa/bin/tfactl status

/opt/oracle.ahf/tfa/bin/tfactl toolstatus

5) syncnodes should be auto . below is just for reference 

tfactl syncnodes

Reference : 

Remove existing AHF and install latest AHF 21.4.1 as per MOS Doc ID 2832630.1
