I think you have a couple of options. Depending on your retention policy, you may want to try "crosscheck archivelog all;" followed by "delete expired archivelog all completed before 'sysdate-30';" (or some number you feel comfortable with).  

You should add "crosschecks archivelog all;" "crosscheck backup of database;" and "delete noprompt obsolete;" statements to the start of the rman scripts. But be sure you check your retention policy and don't step on stuff you'll need later.

Okay,  

Iím pretty new to RMAN and apparently Iíve been pretty stupid and not run some sort of maint to clean up my backups. I bag only that I got pulled to higher priorities and did not fully understand RMAN.  

Anyway, I have a RMAN backup job being executed each night at 10PM using Symantec. So, my backup goes straight to tape. The backup runs fine. But, since the 7th, Iíve been getting tons of this in my log: kccrsz: denied expansion of controlfile section 15 by 6481 record(s)   the number of records is already at maximum value (65535) krcpwnc: following controlfile record written over:  RECID #182457 Recno 3109 Record timestamp  07/19/10 22:13:00

I have my control_file_record_keep value set to 45 days. Where I Ďve been stupid is in not running the Obsolete(?) command to delete and purge the old backups.  

My issue now is that I suspect I will have a bunch of this generated again tonight at 10PM and I think it interfered with another job I tried to run. The tapes containing the older backups are no longer available.  

So, in my panic scan through the documentation, Iím trying to find a command that will purge all the obsolete records from my control file without having the backupsets available on tape. Iíve opened a SR with Oracle, but, this list normally responds faster. What is the proper command string I need to issue to get my control file cleaned up, and not crash my system.  

So..in a slight bit of a panic till I get his taken care ofÖÖ  

THANKS!!
