You are encountering the following error while trying to start/stop the apache
"The field PARAMETER.CONFIG could not be located or read."
The adapcctl.log carries the following errors:
Cannot read value from field PARAMETER.CONFIG
Cause: The field PARAMETER.CONFIG could not be located or read.
You upgraded to RDBMS 18.104.22.168 from RDBMS 8.0.6, but the instance was fine for a couple of days after the upgrade. This problem suddenly cropped up.
Your guest user is end-dated
That is the sole reason you are getting this error.
Back up your FND_USER TABLE
Run the following command update fnd_user set end_date=null where user_name='GUEST';
Retest with adapcctl.sh
