RMAN backup fails atlast during resync catalog with ORA-00001

Question

Hi Everyone,
Database version:10.2.0.2.0
single instance database
My Rman backups were running fine but today i got the error , almost at the end of backup
Finished Control File and SPFILE Autobackup
released channel: t1
released channel: t2
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03008: error while performing automatic resync of recovery catalog
ORA-00001: unique constraint (RMAN.CKP_P) violated
Recovery Manager complete.
This problem occured 2 days before.I connected to catalog and ran a resync catalog and the backup worked fine for next day.
Now again today iam experiencing the same problem.
Any help would be great

Answer 1

Thanks for the reply
SQL> select * from rman.rcver;
VERSION
10.02.00.00
10.02.00.02
when i do the resync catalog manually it works fine.only during the end of backup it throws me the error;
was wondering whether can i disable the primary key constraint on CKP table so that i can avoid the error.
since its a live system im thinking lot before i do anything
Thanks
