Suresh Thalamati updated DERBY-239:
-----------------------------------
Attachment: onlinebackup1.html
minor updates to the spec:
- Procedure can not be overloaded with different number of arguments in
Derby. Added the keyword "ONLINE" to the new backup procedures to
differentiate them from the old procedures.
-- jar file handling.
> Need a online backup feature that does not block update operations when
> online backup is in progress.

> Key: DERBY-239
> URL: http://issues.apache.org/jira/browse/DERBY-239
> Project: Derby
> Type: New Feature
> Components: Store
> Versions: 10.1.1.0
> Reporter: Suresh Thalamati
> Assignee: Suresh Thalamati
> Attachments: onlinebackup.html, onlinebackup1.html, onlinebackup_1.diff,

> 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.
