Minor point: Pete and I both work in the same group; it is just our sig
information that differs. :-)
It would help to know which TSM server version you are using, and what
your tsmjbbd.ini file looks like. Note that journal-based backups require
a 4.2.0 (or higher) TSM server as well, so if you are running at 4.1 or
less, then that explains why the journal backups aren't working.
About the IDLETIMEOUT question: if it is simply the producer session
timing out, I wouldn't bother increasing IDLETIMEOUT. If it is idle for an
hour at a time, then whatever time is taken to re-establish the session is
neglible. Note that IDLETIMEOUT messages are not necessarily indicative of
problems, and this sounds like just such a case.
Where are you seeing the "psFsMonitorThread" message? As far as I know,
this should only appear if you have tracing enabled. Trace messages are
intended for use by IBM service and development, so they are not
documented.

Subject: ***The JOURNALED BACKUP saga continues...***
****Any *SMers using NT Journal Backups****

I have read all of the information about Journal Backups in the "Tivoli
I have read all of the information about Journal Backups in the "Tivoli
Storage Manager for Windows Using the Backup-Archive Client" Manual and
also
the "4.2.1 READMe for NT" and it seems that there is more information
needed
on the behavior of Journal-Based Backups!
I have an NT 4.0 client with TSM 4.2.1.15 (I will soon be upgrading to
4.1.2.20) client installed which it processes approximately 290,000
objects
with about 2,200 (less than 1%) changing on a daily basis.
If the amount of daily change activity is less than 5% is it still
beneficial to use Journal Backups?
When I first upgraded to 4.2.1.15 from 4.1.2.0, I decided not to perform a
Journal backup on this particular client, so I DISABLED the service. 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.

Between 21:32:08 and 00:20:31 (almost 3 hrs) is when I see multiple
sessions
terminating due to the idlewait time of 60 mins.
Should I increase the IDLEWAIT time to 180 mins. (3 hrs) or will that only
eliminate the multiple sessions timing out or increase the performance of
my
backup?
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."
