Answers and comments to questions ..... >>> When will ver 5.1 Journal Sevice be out?
Tentative GA for 5.1 client is beginning of second quarter of this year. There is a formal beta program, if you are interested contact me offline and I will provide you with details. >>> Does it require ver 5.1 of TSM Server as well or does it work with 4.2.1? I don't believe so. >>> How do I disable logging to jbberror.log? On some servers it gets very big Unfortunately you can't but as previously stated the erroneous message logging to the jbb and ntevent logs should be fixed in version 5.1. Hope this helps ....

Keep in mind that a normal full incremental must be done on a file system being journaled to create a valid journal before journal based backup will work. If the Journal Service is stopped all journals are deleted and obviously will no longer valid when the service is restarted so a full incremental must be performed (and completed) before journal based backup will work again. The version 5.1 journal service has a setting to override this behavior, that is to allow a journal to remain valid when the file system goes offline or the service is stopped and restarted. >>> It seems as if the Journal Engine Service is not working properly! >>> I still >>> see sessions terminating due to the extensive processing/querying >>> that the >>> producer thread does while in an idlewait status. I think what is happening is that a full incremental is being forced because the journal was deleted when you stopped the service. Note that you can override journal based backup when a valid journal exists by using the -nojournal option in the backup client.. >>> Also, if anyone can explain this message it would be greatly appreciated? >>> >>> "psFsMonitorThread(tid 1044): Object 'C:\WINNT\Temp\TMP5.tmp' was deleted >>> after notification." This message is erroneous and shouldn't be logged as an error (this is fixed in the version 5.1 journal service). Basically what it means is that a change notification was generated for an object which was deleted before journal service could process the notification. I mistakenly thought this to be an unusual type of error condition but it turns out to happen quite frequently when applications create and delete temporary files in a very short time span. Hope this answers your questions .....

On Tuesday, I started the Journal Service so it could begin its journaling process and log any changed objects or its attributes in the journal database. The backup still took 9.5 hours to complete with the same behavior as without Journaling. So, I continued to let it run the next night and it still took 9.5 hours as well. It seems as if the Journal Engine Service is not working properly! I still see sessions terminating due to the extensive processing/querying that the producer thread does while in an idlewait status.

Also, if anyone can explain this message it would be greatly appreciated? "psFsMonitorThread(tid 1044): Object 'C:\WINNT\Temp\TMP5.tmp' was deleted after notification."
