session_notify script
The session_notify.cmd script (on Windows) and the session_notify script (on UNIX) run on the master server. It's called at the end of a backup session if at least one scheduled backup succeeded. NetBackup passes no parameters to this script. Scheduling is suspended until this script completes, so no other backups can start until that time.
The scripts are located in the following directories:
On Windows: Install_path\NetBackup\bin\session_notify.cmd
On UNIX: /usr/openv/netbackup/bin/session_notify
