Thanks!
What is weird is that there doesn't seem to be anything to release.
TSM is reporting that it has only 12,944 free blocks.
After deleting 12% of the files (65m) and expiration completing,
we were expecting the free blocks to be in the millions.
I don't need the space back, I just want to know that TSM/DB2
will reuse the space. Instead, overall db size just keeps
increasing!!! As you can see below, the db keeps
growing some number of MB per day.

Hi Rick!
Here is the procedure to release space to the operating system on a 6.3 server:

Subject: Does a DB2 db ever shrink?
Hi,
On one of our TSM v6.3.5 databases we deleted two nodes which totaled 65m
files. After doing this we haven't seen any shrinkage in the database size.
date #FilesInDb DbGB
11/01/2015 504786214 701785
11/08/2015 436723183 701676 <= -65m files gone!
11/17/2015 436456172 702185
The free db2 blocks (today) is 12,944.
By deleting the two nodes we dropped the number files by 65m files. But the
database itself hasn't changed in size (filesystem size) or free blocks inside
the db. The db2 is set to auto-reorg (the default).
Q) Why wouldn't our db2 db shrink, or, have gobs of free db2 blocks?
Thanks
Rick
