If Adpatch Fails due to pre-requisite Patch or for some other reason and a lot of time has already been spent since the patch started running then , instead of applying this patch from begining you need to do the following steps in order to save the time you spend while applying the patch.


1. Using the adctrl utility, shutdown the workers.
a. adctrl
b. Select option 3 “Tell worker to shutdown/quit”

2. Backup the FND_INSTALL_PROCESSES table which is owned by the APPLSYS schema
a. sqlplus applsys/<password>
b. create table fnd_Install_processes_back
as select * from fnd_Install_processes;
c. The 2 tables should have the same number of records.
select count(*) from fnd_Install_processes_back;
select count(*) from fnd_Install_processes;

3. Backup the AD_DEFERRED_JOBS table.
a. sqlplus applsys/<password>
b. create table AD_DEFERRED_JOBS_back
as select * from AD_DEFERRED_JOBS;
c. The 2 tables should have the same number of records.
select count(*) from AD_DEFERRED_JOBS_back;
select count(*) from AD_DEFERRED_JOBS;

4. Backup the .rf9 files located in $APPL_TOP/admin/<SID>/restart directory.
At this point, the adpatch session should have ended and the cursor should
be back at the Unix prompt.
a. cd $APPL_TOP/admin/<SID>
b. mv restart restart_back
c. mkdir restart

5. Drop the FND_INSTALL_PROCESSES table and the AD_DEFERRED_JOBS table.
a. sqlplus applsys/<password>
b. drop table FND_INSTALL_PROCESSES;
c. drop table AD_DEFERRED_JOBS;

6. Apply the new patch ( say pre-req patch).
Once this Pre-req Patch is applied successfully.

7. Restore the .rf9 files located in $APPL_TOP/admin/<SID>/restart_back
directory.
a. cd $APPL_TOP/admin/<SID>
b. mv restart restart_<patchnumber>
c. mv restart_back restart

8. Restore the FND_INSTALL_PROCESSES table which is owned by the APPLSYS
schema.
a. sqlplus applsys/<password>
b. create table fnd_Install_processes
as select * from fnd_Install_processes_back;
c. The 2 tables should have the same number of records.
select count(*) from fnd_Install_processes;
select count(*) from fnd_Install_processes_back;

9. Restore the AD_DEFERRED_JOBS table.
a. sqlplus applsys/<password>
b. create table AD_DEFERRED_JOBS
as select * from AD_DEFERRED_JOBS_back;
c. The 2 tables should have the same number of records.
select count(*) from AD_DEFERRED_JOBS_back;
select count(*) from AD_DEFERRED_JOBS;

10. Re-create synonyms
a. sqlplus apps/apps
b. create synonym AD_DEFERRED_JOBS for APPLSYS.AD_DEFERRED_JOBS;
c. create synonym FND_INSTALL_PROCESSES FOR APPLSYS.FND_INSTALL_PROCESSES;

11. Start adpatch, it will resume where it stopped previously.
