I've been implementing Journal Based Backups for the first time using the 5.3 Windows client and thought I'd share some of my experiences and issues.
According to the Problem Determination Guide, there is a tool called DBViewB.EXE for testing the validity of a filesystem journal database file. The corresponding tool for v5.1 and v5.2 was called DBView.EXE and was available as part of an unsupported download called JBBTools.zip. A link to this is included in the TSM Journal Based Backup FAQ (IBM document reference 1155524). However the database structure has changed in 5.3 and the old tools no longer work. Does anybody know where I can find a copy of DBViewB.EXE as this information seems to have been omitted from the Problem Determination Guide? While I'm on the subject of the change to the database structure in 5.3, the new journal files have a '.jbbdb' extension, but these files are not part of the default list of files to be excluded from the journaling in TSMJBBD.INI. However the old journal database files are excluded. Surely this is an omission? Finally, the NLSREPOS entry in the TSMJBBD.INI file defaults to DSCAMENG.TXT. This causes a warning if you try to run the Journal Service as a foreground process (TSMJBBD.EXE i) as this file does not exist in the BAClient directory. I was under the impression that DSCAMENG.TXT had been superseded since v5.2 by DSMENU.TXT and that the existence of DSMAMENG.TXT in the API directory was only for backward compatibility. I'll try logging a call with IBM Support but wondered if anybody had similar experiences. Don't get me wrong, I think JBB is excellent. I've managed to reduce the daily backup of a file system containing 5.6 million files from 9 hours to 8 seconds! Regards Neil Schofield Yorkshire Water Services Ltd.
