Yes. Why don't you post what you are doing as far as backups. Are you doing
fulls, incrementals? How long do you need to keep them for recovery purposes?
You can start a rman session and enter "show all;" to see some of the default
settings as well.

I’ve not fully implemented my retention schedule. I’m still learning RMAN.
RMAN got started before I was ready and understood all of these parameters I
needed to do.
Does that fact that I don’t purge my archive logs make entries into the control
file?

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,
I’m pretty new to RMAN and apparently I’ve 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, I’ve 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)

I have my control_file_record_keep value set to 45 days. Where I ‘ve 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, I’m trying to find a command
that will purge all the obsolete records from my control file without having
the backupsets available on tape. I’ve 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 of……
THANKS!!
