Terry,

Yes, we use TSM JBB's on an MSCS Win2K AS server - it's a production
system, and since we've got the JBB's up and running properly (a few
probs to begin with) we haven't experienced a failover to the 'B' system
to see how the JBB's respond. Since 5.1 client there is a
PreserveDBonexit setting which is designed to keep the journal alive if
the tsmjbbd daemon goes down, and should keep the journal valid during a
failover.

We have a floating TSM client that goes with the clustered drive, and
the journal database for the clustered drive lives on the clustered
drive (change the JouranalDir=... in the tsmjbbd.ini options file under
the [JournaledFileSystemSettings.X:\] stanza). We're using TSM Client
5.1.6.7. 

Check out the 'IBM Tivoli Storage Manager for Windows Backup-Archive
Clients Installation and User's Guide Appendix D around p410,412 for
more details on getting JBB's to work with MSCS.

Subject: TSM Journaling on a cluster


Hi -

Has anyone used journaling on a cluster?  If so, any information,
problems, etc, would be helpful. I do know how to set it up, but just am
curious about your experience with it.

We have a cluster that takes 16 hours to inspect 9million files, but it
only backs up maybe 30k to 50k of these.  We are thinking about using
the journaling cluster service for v 5.2.2.

Thanks

-- Terry
