Greeitngs,

I noticed in our Oralce9i, that there is a large number of archived redolog files.
I tried the following commands to delete them using rman but could not.
Some of them go back as far as last August. It is currently using almost 29GB of disk usage.
I tried using the following commands but non of them seem to see these files.
When I try to list them I got only one file.
What are the available options to delete them?

Thanks.

The archive logs are probably from a previous incarnation of the database. What is the output of:

RMAN> list incarnation;

If there are previous incarnations, then you can probably just delete the older archive logs if you are certain that you've recently got a successful backup.

Thanks for all your info.
I tried the list incarnation but found only one instance:
RMAN> list incarnation;

using target database controlfile instead of recovery catalog

List of Database Incarnations
DB Key Inc Key DB Name DB ID CUR Reset SCN Reset Time
------- ------- -------- ---------------- --- ---------- ----------
1 1 APPDB 3286426219 YES 1 04-AUG-06

And the archived redologs go back to that date as well.

Any suggestions.

Thanks.

What is your value for CONTROL_FILE_RECORD_KEEP_TIME and the output for:

RMAN> list backup;

* Do you get any output with SELECT * FROM V$RECOVER_FILE ?
* Have you excluded any tablespaces from backups?
* How are you deleting the backup sets themselves?

What's strange is the fact that your command for DELETE ARCHIVELOG ALL should have prompted to delete the one archivelog that your LIST command was showing.
