Balance workloads

Overview

To balance workloads...

1. Decide which appserver you want to cluster.
2. Decide whether you want to replicate data.
3. Deploy the application onto the appserver.
4. Set the appserver to be the first member of a cluster.
5. Add more cluster members.
6. Set a backup cluster.
7. Start the cluster.

The default timeout value for the JVM property...

com.ibm.CORBA.RequestTimeout

...is 0, which means wait forever.

If the application is experiencing problems with timeouts, or if system is configured for failover situations, to set an appropriate non-zero value, use...

LaunchClient -CCD

If the workload management state of the client refreshes too soon or too late, change the interval setting of the property...

com.ibm.websphere.wlm.unusable.interval

For stand-alone Java clients, located on a different machine from the appserver, that have no administrative server, define a bootstrap host by adding the following line to the JVM arguments for the client:

-Dcom.ibm.CORBA.BootstrapHost=dmgr_host_name
