How to backup the current autopatch session in R12

Issue:

Adpatch is running and fails on one of the workers.  To fix this worker and
continue with the patch installation, a new patch needs to be applied.
Considering that only 1 adpatch session can run on an instance at any given
time, how can a patch be applied when adpatch is already running?


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.
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.
