I am in the process of planning a TSM configuration for dual

on reports from other sites that have set up library managers,
I expect a database size of about 200 megabytes for each
library manager. I expect to be using TSM Version 6. The
documentation indicates that the minimum size for the
active log is 2 gigabytes. This size will double if I mirror
the active log, as I would prefer. Is there any way to
avoid the absurdity of an active log 20 times as big as the
database it supports?

use TSM v 5.5 ;-)

The DB2 active log is made out of 500MB files. You need 2 to be able
to perform any log circulation, 4 if you want to be able to support
transactions that span two logfiles (I guess, judging from this
minimum). Maybe you could perform unsupported tweaks in DB2 te
decrease the size of the logfiles, but I would just learn to live with
the 2 GB minimum size.
