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:
- Start the application server and ensure that Rational Focal Point is
running.
- Set a multicast group address in the database by setting
an unused administratively-scoped (local) multicast address on your
network.
- Log on to Rational Focal Point.
- Click 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.
- Click Execute.
- To use a common help URL across the clustered instances,
click , 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
