Perform the tasks provided here, after the RPM installation.

1. Run this command to verify the installation is successful:
   1. Go to the folder /var/log/ocsm file.
   2. Verify if the following log file exists: ocsm_installed_*.log.
2. Adjust the firewall to access the Session Monitor applications:
   1. Run this command to allow the firewall to access the HTTPS service (port 443):

      firewall-cmd --permanent --zone=public --add-service=https

   2. (Optional) If you are planning to configure the system as a Mediation Engine, allow the firewall to access the probe connection by doing these tasks:
      • For SBC (embedded) probes:

        firewall-cmd --permanent --zone=public --add-port=4739/tcp
        firewall-cmd --permanent --zone=public --add-port=4740/tcp

      • For standalone probes:

        firewall-cmd --permanent --zone=public --add-port=4741/tcp
        firewall-cmd --permanent --zone=public --add-port=4742/tcp

      Note:

      The ports 4740 and 4742 are the preferred ports for connecting to SBC / standalone probes respectively. So, the firewall should be opened for ports 4739/4741 only if you are agree to have non-TLS connections.
3. Reload the configuration by running the following command:

   firewall-cmd --reload

   Note:

   If you are planning to enable additional services, see the content about network security in the Oracle Communications Session Monitor Security Guide Oracle Communications Session Monitor Security Guide for a complete list of services and their respective ports.
