Hi. I was just wondering if someone could help me understand the
relationship between the recv_hist_reten tion value and archive logs
(and pruning of history file).
My understanding is that the history file will be automatically pruned
at the number of days specified in the recv_hist_reten tn parameter.
First of all, is that correct? Secondly, does the archive logs, that
are older than the value in recv_hist_reten tn value, also get deleted
automatically. Kind of like "prune history xxxxxxxxxx and delete".
Thanks in advance,
Kush

Right, the file gets pruned of entries older than the number of days
specified, but...
NUM_DB_BACKUPS controls also what gets PRUNED. No entry that refers to logs
and backups part of the value (say 5 which makes the restore set) will be
deleted if older than the prune day value.
The following Google search woll help you: db2 prune and delete
ASFAIK, the actual backup images do not get deleted in V8.2.

If you are using Automatic backups, the backups greater than the
NUM_DB_BACKUPS are automatically deleted if they are on disk.
The logs are not so elegantly handled. A "PRUNE HISTORY xxxxxx AND
DELETE" is required to have DB2 delete old archive logs.
In V9, I have a query to generate the PRUNE statement using the new
sysibmadm.db_hi story view. The xxxxxx timestamp is:
select min(start_time) as minbkup
from sysibmadm.db_hi story
where operation = 'B'
and operationtype in ('F','N')
This subquery is wrapped in a larger query that formats the command.
Dale McInnis (IBM) unofficially mentioned that they were
re-architecting this process in a future version in an IDGUG
presentation.

Thanks guys. This answers my question basically that I DO need "Prune
History xxxxx and DELETE" or "Prune Logifile xxxxx " . Thanks for your
answers.
