The only way to reorganize the database is an UNLOADDB, LOADFORMAT, LOADDB.
Nothing else accomplishes this. If your database has had lots of filespace
deletions the tree can get severly unbalanced and negatively affect
performance.

Subject: Question about database fragmentation
Hi All
I wonder who can help me with this. Does the database become very fragmented
over time? If so, is there any way of telling how much? Also, is the only
fix for this to do a dump and reload of the database?
If the answer to the final question is yes, how easy are dump/reloads?
We recently upgraded from TSM 3.7.3.8 to 4.2.2.12 and had to run an auditdb
first (which completed without any problems).
Many thanks in advance
All the best
