12.2.5 E-Business Suite Adop Phase=fs_clone Fails With Error '[UNEXPECTED]Cannot run fs_clone while an existing patching cycle is active' Due to Null apps_jdbc_connect Descriptor In Patch Context File (Doc ID 2150588.1)

SYMPTOMS
E-Business Suite 12.2.5 Applications DBA, Upgrade Related issues
The following error occurs when running FS_CLONE:
ERROR
-----------------------
Finished upgrade of 12.2.0 to 12.2.5.  Now when running adop phase=fs_clone the following error occurs:
Checking for existing adop sessions.
  Continuing with existing session [Session ID: 10].
  Session Id : 10
  Prepare phase status : NOT COMPLETED
  Apply phase status : NOT COMPLETED
  Cutover phase status : NOT COMPLETED
  Abort phase status : NOT COMPLETED
  Session status : FAILED
  [UNEXPECTED]Cannot run fs_clone while an existing patching cycle is active
CAUSE
The s_apps_jdbc_connect_descriptor string is removed from the Patch file system context file.
Using the string from the Run file system context file to replace the s_apps_jdbc_connect_descriptor value in the Patch file system context file is a valid workaround.
SOLUTION
To resolve the issue test the following steps in a development instance and then migrate accordingly:
1. Update the patch context file with s_apps_jdbc_connect_descriptor.
2. Copying the value from the Run to the Patch context file.
3. Run FS_Clone again and confirm the error no longer occurs.
