7.2.5 Using workload management - a sample procedure

The following procedure shows how to implement workload management by cloning application servers. In this scenario, client requests are distributed among the clones of an application server on a single machine. (A client refers to any servlet, Java application, or other program or component that connects the end user and the application server that is being accessed.) In more complex workload management scenarios, you can distribute clones to remote machines.

  1. Decide which application server you are going to clone.
  2. Deploy the application onto the application server.
  3. After configuring the application server and the application components exactly as you want them to be, create a server group. The original server instance becomes a clone that is administered through the server group.
  4. Create one or more clones of the server group.
  5. Start all of the application servers by starting the server group.

Workload management automatically begins when you start the clones of the application server.

Note: You need to define a bootstrap host for stand-alone Java clients -- that is, clients that are located on a different machine from the application server and have no administrative server for the client. Add the following line to the Java Virtual Machine (JVM) arguments for the client:

-Dcom.ibm.CORBA.BootstrapHost=machine_name

where machine_name is the name of the machine on which the administrative server is running.
