RMAN-06900 RMAN-06901 ORA-19921

Received RMAN-06900,RMAN-06901 and ORA-19921 while logged in to RMAN prompt to verify daily backups. (OS:Redhat linux 6.5)

WARNING message:

[oracle@primary logs]$ rman target /

RMAN-06901: WARNING: disabling update of the V$RMAN_STATUS and V$RMAN_OUTPUT rows
ORACLE error from target database:
ORA-19921: maximum number of 128 rows exceeded
RMAN>

On further diagnosing and suggested by OERR utility, I have realized there is one old active session from Aug 23, as mentioned below.

[oracle@primary ~]$ oerr ORA 19921
19921, 00000, "maximum number of %s rows exceeded"
// *Cause: The maximum number of rows in the V$RMAN_STATUS or V$RMAN_OUTPUT
// table has been exceeded.
// *Action: Close some of existing and unused RMAN connections and sessions.

So lets find out old session with ps -ef:

[oracle@primary logs]$ ps -ef|grep rman
oracle 543 32693 0 10:50 pts/4 00:00:00 grep rman
oracle 19783 19782 47 Aug23 ? 1-07:13:42 rman target /

There is one old active session above, OS ID: 19783, since 23 aug.

[oracle@primary ~]$ date
Fri Aug 26 10:57:13 IST 2016
[oracle@primary logs]$ kill -9 19783

After successfully killed old session, we are no more facing mentioned list of warnings, as below:

[oracle@primary logs]$ rman target /
