Fragmented Database Maybe?
2003-02-28 10:39:34
Hi All TSMers
I'm Running TSM 4.2.2.12 on a Solaris 2.7 server (E250 400Mhz, 1GB mem). We
have been having severe performance issues recently and moved our database
volumes off onto a new disk. To do this we formatted a new db volume and
copy, and then we deleted the original ones. TSM immediately went into
action and moved the database volumes into the new volume.
The volume sizes were 5000Mb
2500Mb
1000Mb
After they each finished there was a summary that showed number of bytes
moved. In this case the results were as follows:-
5000Mb - 947,912,704
2500Mb - 2,621,440,000
1000Mb - 1,048,576,000
Now I can see that the figures for the 1000 and 2500 are correct, but the
5000 volume is way off! Any ideas why I am seeing this result. Is it just a
bug or is the DB massively fragmented or something?
Also, is there anyway to see if indeed the database is fragmented?
Many thanks to all who help as this is very puzzling.
All the best

Subject: Cache Hit Percentage
Since upgrading to TSM 5.1.6.2 on AIX 4.3.3 I have now noticed my cache hit
percentage drops below 98% every day. Reset bufpool brings it back to
100.00% but after 24 hours it will again be below 98%. While on TSM 5.1.5.2
it was rarely below 98.5%. Has anyone else seen this behavior?
