Freeing up RTC database space

Brian Reynolds (1689) | asked May 20 '13, 3:32 p.m.
If you actually delete entire files in RTC, as opposed to versions, is the space automatically
reclaimed in the underlying database? That is, if you delete a 5  1GB files in RTC, will the
database shrink 5 GB?

Are there any official recommendations about how to shrink the DB?

what kind of Files?

source  or attachments?  Attachments are almost impossible to remove.
if they are Source.. I assume there is a history, and thus all prior versions are retained, in case you should
want to go back.

Hi Brian, to me it seems that this is more of a database capability question.

The ways of reclaiming spaces from databases are different for each database systems. It is not clear from your post which database system you are using, but assuming you are using DB2, I think there is a way to setup automatic reclaiming of spaces through a policy if automatic maintenance is enabled or you can also check table reorganization for DB2.
