Session sharing in HA mode issue

In BMC Atrium Single Sign-On High Availability (HA) mode, session sharing can fail in some specific network environments when the default protocol (multicast) is used by ApacheMQ. ApacheMQ is a third party component which is used by Atrium Single Sign-On to inform all nodes in the cluster about sessions’ creation and termination events. If  session sharing fails, change the configuration settings to an alternative protocol.

To configure point-to-point sessions sharing

Perform the following on each node in the HA cluster.

  1. Navigate to the <AtriumSSOinstallationDirectory>/tomcat/webapps/atriumsso/WEB-INF/classes/ directory.
  2. Edit the activemq.xml file.
  3. Replace the following tag:
    <transportConnector uri="ssl://localhost:0?transport.needClientAuth=true&amp;daemon=true" discoveryUri="multicast://default?daemon=true&amp;group=atsso" />

    with:
    <transportConnector uri="ssl://<hostname>:<port>?transport.needClientAuth=true&amp;daemon=true " />


    where:
    hostname — The host name of the current node.
    port — The port which will be used for the sessions sharing on this node.
  4. Replace the following tag:
    <networkConnector uri="multicast://default?daemon=true&amp;group=atsso" />

    with:
    <networkConnector uri="static:(ssl://< hostname>:<port>?daemon=true[,ssl://< hostname>:<port>?daemon=true,…])"/>

    where:
    hostname — The host name of another node in the HA cluster.
    port — The port which is used by another node for session sharing.

    Note

    The <hostname>:<port> pair is specified on another node in the <transportConnector /> tag.
  5. Save the file.

Note

  • Shutdown all the nodes in the cluster after configuring point-to-point session sharing.
  • Do not start all the nodes at the same time. Start each node beginning from the first node only after the previous node is fully started.
