Try relinking the RMAN executable:

cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk irman

After I ran relink,
cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk irman

still got the same error:

Did something in your environment change?

You might try relinking all executables. (there is a script in ORACLE_HOME/bin called relink)

It should be as simple as "relink all"

Make sure to shutdown all Oracle programs before relinking.


If that fails, its time to open a SR with Oracle.

Do I need to shutdown all instances before I ran "relink all"?

shut down instances and listener. Logged in as oracle account and ran
relink all
and
make -f ins_rdbms.mk irman.
Tried it again. Still got the same error.

I think the only next step is to call Oracle / file a service request.

Something definitely amiss in your environment.

Oracle classifies this error as "Not supposed to happen"

If you are unsupported, the only other option I can think of is to reinstall the Oracle software (the exact version that the database was created under).

Make sure ORACLE_SID is set correctly to your target prior to running RMAN

Also I've never seen the syntax you used above to connect to the catalog (connect catalog /@rmansrv) ??. I use the catalog owner which is usually named rman, see below.

export ORACLE_SID=ORA1
rman target / catalog rman/cat@CAT
