RMAN backup failed with ORA-01400

The backup of one of our production servers suddenly has following errors in the log.

RMAN-03014: implicit resync of recovery catalog failed

RMAN-03009: failure of partial resync command on default channel at 10/06/2008 10:54:54

ORA-01400: cannot insert NULL into ("RMANCAT"."ROUT"."ROUT_SKEY")

It looks like this is a hit of Oracle bug

Bug No:5528078

ORA-01400: CANNOT INSERT NULL INTO ("RMAN"."ROUT"."ROUT_SKEY")

The strange thing is I didn't had any changes lately in production. I am not quite sure what event has triggered this bug.

The workaround involve changing script $ORACLE_HOME/rdbms/admin/recover.bsq and UPGRADE CATALOG .

This error usually happens after database migration.
