RMAN-20035

I received this error today while configuring RMAN on one of the databases.

RMAN-20035: Invalid high RECID error

In this case Note 273446.1 from Oracle support was helpful.

It suggests to unregister the database using DBMS_RCVCAT.UNREGISTERDATABASE procedure.
and then register the database again.

This is what i did and the problem resolved as of now.
The following commands are helpful -->

select * from rc_database where dbid = DBID;

exec dbms_rcvcat.unregisterdatabase(DBKEY, DBID);
