Cause: The collection name has already been used and currently exists in the Oracle Trace admin COLLECT.DAT file. If the collection is inactive, this record will eventually be discarded.
Action: Specify a new collection name or force clean up of Oracle Trace admin .dat files by executing the otrccref image (once all processes have detached from these files).
