[ http://issues.apache.org/jira/browse/DERBY-239?page=all ]
Suresh Thalamati updated DERBY-239:
-----------------------------------
Attachment: onlinebackup_2.diff
Fix to the problem found by Øystein while reviewing the previous online
backup patch(online_backup1.diff).
Backup of a container code was doing a seek incorrectly on the file container
instead of the backup file.
Tests: All tests passed on jdk142 Windows XP.
It would be great if some one can commit this patch.
Thanks

> Currently Derby allows users to perfoms online backups using
> SYSCS_UTIL.SYSCS_BACKUP_DATABASE() procedure, but while the backup is in
> progress, update operations are temporarily blocked, but read operations can
> still proceed.
> Blocking update operations can be real issue specifically in client server
> environments, because user requests will be blocked for a long time if a
> backup is in the progress on the server.
