If the hostname of the Sentinel server changes, you must update any remote Correlation Engines or Collector Managers to point to the updated hostname. To do this, you run the configure.sh script on each remote machine.
The configure.sh script is located in /opt/novell/sentinel/setup. Run this script on each remote machine to update the hostname and IP address of the Sentinel server in the remote machine’s configuration files.
The configure.sh file also allows you to change the password of the appuser. The appuser is an internal Sentinel identity that is used to establish a connection and interact with the PostgreSQL database.
