CLEARING an ADOP patching session

In some case adop prepare phase fails due to some issues and if you wish to apply any patch in hotpatch mode, it will fail with below errors

[STATEMENT] There is already a session which is incomplete. Details are:
[STATEMENT]     Session Id: 2
[STATEMENT]     Prepare phase status: R
[STATEMENT]     Apply phase status: N
[STATEMENT]     Cutover  phase status: N
[STATEMENT]     Abort phase status: N

[STATEMENT]     Session status: F

[ERROR]     Cannot apply hotpatch as another online patching cycle is going on

[ERROR]     Unrecoverable error occured. Exiting the current session.

[STATEMENT] [START 2019/10/22 16:13:00] Unlocking sessions table

Can't call method "close" on an undefined value at /u01/apps/TEST/fs1/EBSapps/appl/au/12.0.0/perl/ADOP/Phase.pm line 239.

Now, if you try to cleanup the previous session using below

$ adop phase=cleanup

  [ERROR]     Error: Pending session of prepare/apply/cutover exists

  [ERROR]     Hint: Before trying cleanup complete the pending session

  [STATEMENT] [START 2019/10/22 16:18:36] Unlocking sessions table

  [STATEMENT] [END   2019/10/22 16:18:36] Unlocking sessions table

  [STATEMENT] Log file: /u01/apps/TEST/fs_ne/EBSapps/log/adop/2/adop_20191022_161746.log

adop exiting with status = 2 (Fail)

The solution is to abort the patching cycle as shown below:

Type Y when prompted 

$ adop phase=abort

...

[STATEMENT]           one patch is already applied for the session id

The above session would be aborted/rolled back. Do you want to continue [Y/N]? Y

[STATEMENT] adop phase=abort - Completed Successfully

$ adop -status
