The problem is that the first run of the RMAN happens successfully and creates backup files in "/psoft/*u02*/...", but the second run looks for file in $OH/dbs (/psoft/*u01*). It is trying to recover files in OH/dbs. In the beginning (yesterday when I started testing) /psoft/u01 was where RMAN was doing the backup. I delete the old backups several times and rerun the RMAN. Somehow RMAN seems to want to restore in the original location of OH/dbs only in the second run.

Is there any command to tell RMAN not to look in OH/dbs while doing the restore in the second run? I run crosscheck after deleting backups.

RMAN *second* run looking for files in OH/dbs (/psoft/u01...) :

My run part of the RMAN script now looks like this:

---

run {
allocate channel oem_disk_backup device type disk; configure CHANNEL device type 'SBT_TAPE' clear; sql 'alter system switch logfile';
CONFIGURE CHANNEL DEVICE TYPE DISK CLEAR; configure channel 1 device type disk clear; configure CHANNEL device type disk format '/psoft/u02/oracle10g/cds/ATES/bkup/%U'; recover copy of database with tag 'incr_ates'; CONFIGURE CHANNEL DEVICE TYPE DISK CLEAR; configure channel 1 device type disk clear; backup as compressed backupset

     incremental level 1 cumulative  copies=1 tag 'incr_ates'
     for recover of copy with tag 'incr_ates'
     format '/psoft/u02/oracle10g/cds/ATES/bkup/%U'
     database plus archivelog delete input;

sql 'alter system switch logfile';

    }
