If there is a way to set your recovery window in O817 you should be able to do it. We went from 8.0.4.6 to 9i and I only used 8.1.7. briefly and only for my catalog database and repository and didn't do rman backups of these. You can tell if you to a 'show all;' in rman. It will show the defaults and allow you to change them. If the recovery window it shown, change it to 180 days and then crosscheck backup; and delete obsolete; HTH, Ruth -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]On Behalf Of Kline.Michael Sent: Monday, April 11, 2005 10:47 AM To: oracle-l@xxxxxxxxxxxxx Subject: Delete obsolete in RMAN on 8.1.7.4 It appears the "delete obsolete" doesn't work in 8.1.7.4 of RMAN. Yet I can "report obsolete" which goes WAY back. How do or can I trim this list. We keep about 6 months, but "report obsolete" is going back almost 2 years now. This is on SUN if it matters.
