RMAN-12012: multiple records for DISK parallelism found in catalog

While trying to restore (TSPITR) using RMAN Catalog I ran into this wired errors stating while allocating channels...


RMAN> recover tablespace abc123
until time "to_date('19-FEB-2013 00:00:00','DD-MON-YYYY HH24:MI:SS')"
AUXILIARY DESTINATION '/ora05/auxdest';

Starting recover at 20-FEB-13
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 02/20/2013 16:43:10
RMAN-12010: automatic channel allocation initialization failed
RMAN-12012: multiple records for DISK parallelism found in catalog

RMAN> exit

Doing some research, found the solution to reset config and try again.

SQL> exec dbms_backup_restore.resetconfig;

Now try again and you will have no issues allocating channels...
