Subject [jira] Updated: (DERBY-239) Need a online backup feature that does not block update operations when online backup is in progress.
Date Sun, 29 Jan 2006 22:56:11 GMT
     [ http://issues.apache.org/jira/browse/DERBY-239?page=all ]

Mike Matrigali updated DERBY-239:
---------------------------------

    Description: 
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.
