ADOP (Online Patch ) 12.2 Steps

 There are below 5 Phases of ADOP(online patching):

1.  PREPARE
2.  APPLY
3.  FINALIZE
4.  CUTOVER
5.  CLEANUP 

Steps:-

1. Download the patch and unzip on patch_top.

2. Must go through Readme.html or readme.txt.

3. Prepare the system for patching

source the run file system

$ adop phase=prepare

4. Check the adop status

$ adop -status

5. Goto next phase called Apply Phase

$adop phase=apply patches=<patch_number>

$ adop -status

6. Goto next phase called Finalize Phase

$ adop phase=finalize

$ adop -status

7. Goto next phase called Cutover Phase

$ adop phase=cutover

$ adop -status

Note : kindly stop the Concurrent manager, go to

$ADMIN_SCRIPT_HOME   -- > adcmctl.sh 

check the status and stop the concurrent manager

stop the concurrent manager adcmctl.sh  stop

To check the status of the concurrent manager 

ps -ef | grep FNDLIBR

if running concurrent manager 

kill the process_id

kill -9 <process _id>

8. Open new terminal, Source the environment 

. /oracle/WEPPROD/EBS1224/EBSapps run

 Goto next phase called Cleanup Phase

$adop phase=cleanup

$ adop -status

Note:

Keep checking Status after every Phase (adop -status)

If there are some reason either the prepare or apply phase failed or any problems then you can abort this patching cycle.

$adop phase=abort

But always remember, after running abort, you must always run a full cleanup as:

$adop phase=cleanup cleanup_mode=full
