RMAN-06035: wrong version of recover.bsq

While trying to connect to RMAN today,  I saw the below error.

RMAN-06035: wrong version of recover.bsq, expecting 11.1.0.7, found 11.2.0.3


Cause: There were multiple oracle homes on this particular database server.

Solution:

Export the ORACLE_SID and ORACLE_HOME.
                Go to $ORACLE_HOME/bin and then try connecting to RMAN

sousurdba1:/home/oracle>cd $ORACLE_HOME/bin
sousurdba1:/u01/app/oracle/product/11.2.0.3/dev/bin>rman catalog rcat/rcat123@sou01pd
