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

Need a online backup feature that does not block update operations when
online backup is in progress.

Project: Derby
Type: New Feature

Versions: 10.1.1.0

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.
