Adding Server Processes 

Use

You can scale a Java cluster by adding server processes to already existing Java instances. This enables optimal utilization of the available hardware resources and of the capacity of the Java dispatcher to handle multiple server processes.

 

Scaling the cluster by adding a server process

Prerequisites

You have installed the basic components of the cluster.

Procedure

When you install your Java instance, SAPInst automatically configures the number of server processes based on the hardware resources that are available.

If you need to add more server processes to an existing Java instance, you can do that manually using the J2EE Engine Config Tool:

Make sure ...

       1.      Make sure that the J2EE Engine system is stopped. For more information, see Starting and Stopping the J2EE Engine.

       2.      Start the Config Tool by running the configtool script file located in the \usr\sap\<SAPSID>\j2ee\<instance name>\configtool directory.

       3.      Select the instance to which you want to add the server process.

       4.      Choose Server → Add Server.

For more information about the Config Tool, see Config Tool.
