Kill Hung RMAN Session

I recently encountered a situation where the RMAN backup job was stuck. I ended the hung session as the database size was only four GB and it had been running for the last four hours. We made some changes to the RMAN command and ran the jobs again. It was completed in under an hour. “Kill Hung RMAN Session in Oracle“.
