Oracle sys grants missing after Schema level export import

During  schema level export/import    there are high  chances of   grants to go missing .    This is  one of case where  sys grants  are found missing  . It  has been  nicely explained  in Oracle Doc 1911151.1 .

Workaround is  to  manually  get DDL  for grants from source database and apply in target  using below   script . 

spool grants_tc.out

col GRANTS for a80

-- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

-- Add below the users and/or roles as appropriate for GRANTEE

-- xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

select 'grant ' || privilege || ' on ' ||'"'||table_name ||'"'||

      ' to ' || grantee || ';' "GRANTS"

 from dba_tab_privs

where owner = 'SYS' and privilege not in ('READ', 'WRITE')

  and grantee in ('TC')

order by 1;

spool off
