Hi Fred,

I just took a v4.2.2.12 AIX server to v5.1.1.6 last Saturday.
All I can say is 'not pretty'. This is due to the SYSTEM OBJECT
problem. If you don't know what this is, you will soon if you
have WinXP and Win2K clients backing up to v4 and pre v5.1.1.6
servers.

The basic problem is that TSM isn't expiring anything in the
SYSTEM OBJECTs filespace. Some of our clients had over 20GB
in these filespaces! Needless to say, the database blew up
while trying to find out what was going on.

To see if you have this problem, you can type in

show version <nodename> "SYSTEM OBJECT" namet=uni > file

(only use namet=uni if the filespace is unicode). Then
check through the file and look for the number of occurrences
of a file, say ROUTE.EXE. A normal SYSTEM OBJECT filespace,
with four versions, shouldn't be over a gig.

The good news is that v5.1.1.6 does NOT have the SYSTEM
OBJECT problem and the new server is doing very well.

I am writing up the post mortem on the conversion and will
post to the list later this week (at the request of Tivoli
level 2).
