Subject: Are snapshot logs purged?

Hello Lists,

I have a set of snapshots refreshing in FAST mode
using snapshot logs. The snapshot log is keep-on
growing as it should and after certain amount of time,
I had to expand the tablespace space under which the
snapshot log is located.

My question is, Is there a way to periodically
truncate or remove records from snapshot logs? Of
course we can make something on our own by scheduling
some delete jobs, but, Is there any default method
available in Oracle?

Any input would be highly appreciated.

Thanks in advance,
Muru
