 OPMN fails to start running adstartall.sh in a 12.2 environment and returns a message to check file adopmnctl.txt.
Error:

 [opmn] [ERROR:1] [] [internal] /u01/APPS/GPROD/fs1/FMW_Home/webtier/opmn/bin/opmn: unexpected exit: status 200

 Cause:

 It might be due to corruption of directory

 Solution:
1. Stop all services.
2. Rename the directory: OPMN/opmn/states  (eg. /u01/APPS/GPROD/fs1/FMW_Home/webtier/instances/EBS*/config/OPMN/opmn/states in the example above.)

3. Restart the services and confirm the error no longer occurs.
