looks good, but it looks like it is missing a file - maybe svn diff did
not pick up a binary file.  From running the tests it looks like I need
a obtest_customer.jar for the new test.

Suresh Thalamati updated DERBY-239:
-----------------------------------

    Attachment: onlinebackup_6.diff

This patch adds code to support online backup when jar operations are running parallel to the backup. Jar files are not logged, but the system catalogs updates are logged when a jar file is added/replaced. If the jar file operations are allowed during the backup, system catalog (sys.sysfiles) table in the backup database can have a reference to a jar file that does not exist in the backup database. And also backup can contain partial written jar files. To make a consistent online backup, this patch:

1) Makes Backup operation wait/fail for all the jar operations activity in progress to complete.
2) Blocks jar file operations when a backup is in progress.

This patch also adds a new test to test the online backup with jar operations.

TESTS : derbyall test suite passed on Windows XP/JDK142

It would be great if some can review and commit this patch.

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

       Type: New Feature

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.
