Archive log backup fails with error user mapped section open

45 Views

Hi am facing a intermittent issue , where my archive log backup fails with error user mapped section open. Possibly when copying init<SID>.ora. My Online backup and archive log backups are in a gap of 2 hours 1st Online Full Backup then Archive Log backup. But when i re-execute the failed task it goes successful. My understanding is that some process is holding the init<SID>.ora due to which the error comes. can you give some suggestions on what should be done.
