Folks,
Management would like to know what kind of impact we would have on the volume
of data we have stored in TSM if we were to lower the retention periods. They are
expecting something like "if we lower the 'retain only version' from 180days to 60
days we will free up X GB of tapes and X GB of database space." Unfortunately no "what
if" tools exist, so I have to build one to accomplish this.
Anybody gone through this exercise? Have any good queries they'd like to share?
It looks like I can get a count of all the objects from the BACKUPS table, but
then equating that to volume of data is going to take another table, although I don't
see how to get that at this point.
To take the first whack at this and get a ballpark figure, I thought I'd at
least get a count of all the inactive objects in the database. You think I should
count DIRs and FILEs or just FILES?
This simple query is not working because I'm not getting the state correct. Anybody
know what an ENUMERATED(BACKUPSTATE); value should be? I tried 0 and 1 and that wasn't
it. I've tried various quotes and values, but can't seem to get it.
TSMSERV1A>select * from backups where node_name like 'TSMHOST6' and filespace_name
like '/export/home' and state like INACTIVE_VERSION
ANR2921E The SQL data type of expression 'STATE' is ENUMERATED(BACKUPSTATE); expecting
a character string expression.

Anybody with more SQL experience want to help?
