ARC2005 Monitor session logon failed due to error %s.
During LOGON processing, ARC will attempt to log on a MONITOR session to collect information about the location of AMPs for performance optimization. If this session can not be logged on, ARC will report a warning indicating the reason for the failed logon. The message is a warning only; ARC will continue with the requested operation. However, backup performance may be affected.
Correct the problem described in the returned error message text, and attempt to run the job again.
