Hi,

I have deleted all old backup sets (from RMAN and TSM), because we got a new tape library. But the first new RMAN backup doesn't have the "backup set number" -> 1
RMAN> list backup;

using target database controlfile instead of recovery catalog

List of Backup Sets
===================

BS Key  Type LV Size       Device Type Elapsed Time Completion Time
------- ---- -- ---------- ----------- ------------ ---------------
271     Full    538M       SBT_TAPE    00:00:28     01-MAY-09      
        BP Key: 27   Status: AVAILABLE   Tag: TEC OFFLINE V1.0
        Piece Name: TEC/685683752/27/1
-------  

How can I reset the backup set number ... Would be nice, if the new backups start with the backup set numer 1.

I don't think this is possible or maybe recreating the control file but you will loose the possibility to use the previous backup.
Why this number is important for you?

Michel,

thank you for your answer. It isn't really important, but it would be nice, if I could do it.

I have exported the control file with:

ALTER DATABASE BACKUP CONTROLFILE TO TRACE;


The result is in the attached file. Maybe I'm blind ... Maybe I'm to stupid ... Maybe both ... I can't find the backup set number in the control file.

P.S. to the Moderator: Thank you for adding the 'code' '/code' Embarassed

Had to edit the message .. I called Michel Michael. Today is really not my day.

The backup to trace does not contain information on backups, this is why I said maybe the next one will start with number one but you will loose information about previous backups and can't use them.

Michel
