How to restart a failed patch in r12



Hi Friends,
Some of my friends asked questions related to adpatch. We have some scenario for adpatch failed. Please find the below details:

Suppose, our adpatch fails due to pre-requisite Patch or some other reasons. But we have already spent lots of time on patching.
So, here we have two options either apply the patch again or apply the patch from where adpatch patch is failed.

Off course, everybody likes to save time. So let’s start the below steps to save time and start the patching from where it was failed.

1. We need to shutdown the workers by below command.
$adctrl

Then select option 3 “Tell worker to shutdown/quit”

2. Now, take the backup of the FND_INSTALL_PROCESSES table
Steps:
Connect as applsys because FND_INSTALL_PROCESS is owned by applsys schema.
 
$Sqlplus applsys/<password>

create table fnd_Install_processes_back
as select * from fnd_Install_processes;

Check the both tables should have the same number of rows.

SQL>select count(*) from fnd_Install_processes_back;
1919 rows selected

SQL>select count(*) from fnd_Install_processes;
1919 rows selected

Same way take the backup of the AD_DEFERRED_JOBS table.

$sqlplus applsys/<password>

SQL>create table AD_DEFERRED_JOBS_back
as select * from AD_DEFERRED_JOBS;

Check the both tables should have same number of rows as we checked in above commands.

Now backup the .rf9 files located at below path directory.
$APPL_TOP/admin/ORA-DATA/restart directory.

Here adpatch session should have ended and the cursor should be back at the UNIX prompt.

$echo $ORACLE_SID
ORA-DATA

$ cd $APPL_TOP/admin/ORA-DATA
$ mv restart restart_back
$ mkdir restart
$ chmod 777 restart

Now we are ready to DROP the FND_INSTALL_PROCESSES table and the AD_DEFERRED_JOBS table.

$sqlplus applsys/<password>
$drop table FND_INSTALL_PROCESSES;
$drop table AD_DEFERRED_JOBS;

Now, we are ready to apply the new patch or say pre-req patch in case if you are missing the pre-req patch.
After Pre-req Patch is applied successfully.

Then restore the .rf9 files located at below location as shown above command
$ $APPL_TOP/admin/ORA-DATA/restart_back
directory.
$cd $APPL_TOP/admin/ORA-DATA
$mv restart restart_<patchnumber>
$mv restart_back restart

Again restore the both FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS table owned by the APPLSYS
schema.
$sqlplus applsys/<password>

$create table fnd_Install_processes
as select * from fnd_Install_processes_back;

$create table AD_DEFERRED_JOBS
as select * from AD_DEFERRED_JOBS_back;

Just cross-check the number of rows for both tables which should be equal from above commands.

And now Re-create the synonyms

$sqlplus apps/apps

$create synonym AD_DEFERRED_JOBS for APPLSYS.AD_DEFERRED_JOBS;

$create synonym FND_INSTALL_PROCESSES FOR APPLSYS.FND_INSTALL_PROCESSES;

Now, we are ready to Start adpatch and it will resume from where it was stopped in previous sessions.

Note: If you ask me frankly, I would like to go through re-apply the patch.

Patch log file location: /u01/oracle/VIS/apps/apps_st/appl/admin/VIS/log

  9. I know this if off topic but I'm looking into starting my own weblog and
    was wondering what all is required to get set up?
    I'm assuming having a blog like yours would cost a pretty penny?
    I'm not very web smart so I'm not 100% sure. Any suggestions or advice would be greatly appreciated.
    Cheers

  11. You actually make it seem so easy with your presentation but I in finding
    this matter to be really something which I feel I might by no means
    understand. It kind of feels too complex and extremely extensive for me.
    I'm taking a look ahead for your next publish, I'll try to get
    the hold of it!
