Did not want to open new topic just for one question, and I think this is the place to ask..
Not correct. Hijacking someone elses's forum thread for your new inquiry is poor etiquette. You are not helping the original poster but are concerned only with what YOU are experiencing in your system environment.
You post has now been branched away to stand on its own and to permit people to respond to YOU.
ALWAYS start your own new post for YOUR questions. Add to someone else's thread ONLY if you are attempting to help THEM.
The old concurrent requests are visible from the target instance with the help of the logs and output files in the INST_TOP
When cloning, INST_TOP is not a must copy directory to the target system. But if you don't copy you will not have the source log and output files on the newly cloned instance. Therefore, deleting the files in the INST_TOP will remove the request files in the application level.
Hope this helps,
