[ 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.
