Setting up clusters for Rational Focal Point

You can set up cluster configurations for IBM® Rational® Focal Point™ on an application server.

About this task

For information about setting up the clusters in Apache Tomcat server and WebSphere® Application Server, see the server documentation.
Notes:
  • Synchronize the time between the systems that are running on a cluster node. Typically, time synchronization between systems is done by using the network time protocol.
  • If you set up clusters in WebSphere Application Server, ensure that Configure HTTP session memory-to-memory replication is not selected. After you set up the clusters in WebSphere Application Server in the custom properties for JVM, add WAS_SERVER_NAME, with the cluster name as the value.

Procedure

In one of the cluster node, perform the following steps:

  1. Start the application server and ensure that Rational Focal Point is running.
  2. Set a multicast group address in the database by setting an unused administratively-scoped (local) multicast address on your network.
    1. Log on to Rational Focal Point.
    2. Click Advanced > SQL and insert the following code:
      insert into projectsetting (pid,name,value) values (-2,'multicast.group.address','<multicast address>')
      For example, to set 239.0.0.1 as multicast address in the network, insert this code:
      insert into projectsetting (pid,name,value) values (-2,'multicast.group.address','239.0.0.1')
      Important: Make sure that this multicast address does not interfere with other multicast address on your network.
    3. Click Execute.
  3. To use a common help URL across the clustered instances, click Advanced > SQL, insert the following code, and click Execute.
    update projectsetting set value='HELP_URL_VALUE' where name='help.alternate.url'  and pid=-2
    For example:
    update projectsetting set value='http://www.example.com:8080/fphelp/index.jsp' where name='help.alternate.url'  and pid=-2
