Enabling session replication for standby Content Manager services

The session replication feature allows for seamless IBM® Cognos® Content Manager failover between an active Content Manager service and a standby Content Manager service.

With session replication enabled, user session data are replicated among all Content Manager instances. If the active Content Manager fails, the user session data is preserved and users continue to use the application without disruption.

Session replication uses two ports to securely communicate with the different IBM Cognos Content Managers configured within a single environment.

Procedure

  1. On a computer where the IBM Cognos Content Manager is installed, start IBM Cognos Configuration.
  2. In the Explorer pane, under Security, click Replication.
  3. Specify the following properties:
    1. Set Enable replication to True.
    2. In the Peer listener port number value box, enter a port number.

      A value of 0 selects the first available dynamic port during the IBM Cognos service startup.

    3. In the RMI replication port number value box, enter a port number.
    Note: The Advanced properties should be used only under guidance from IBM Technical Support.
  4. Save the configuration and restart the IBM Cognos service.
  5. Repeat the steps for each Content Manager instance in your environment.

    The port numbers that you specify do not need to be identical for each Content Manage instance.
