Setting JVM Parameters for the AppNode Manually

This section explains the location of the TRA files in the ActiveMatrix BusinessWorks home folder structure, the JVM parameter settings and the components that are applicable to these settings.

  • The <BW_HOME>/bin/bwcommon.tra file is at the top of the hierarchy. By default, the java.extended.properties or JVM properties are not present in this file. However, you can add these properties explicitly and the properties will be applicable to all the AppNodes in all the AppSpaces.

  • To set the JVM properties at the AppSpace level for all the AppNodes in a particular AppSpace, the JVM properties can be set in the bwappnode-<AppSpaceName>.tra file which is located at <BW_HOME>/domains/<domainName>/AppSpaces/<AppSpaceName>/.

    This will set the JVM properties for all the AppNodes in that particular AppSpace.

  • You can also set or edit the JVM parameters for a particular AppNode in the bwappnode-<AppNodeName>.tra file directly. This file is located at <BW_HOME>/bw/6.3/domains/<domainName>/AppNodes/<AppSpaceName>/<AppNodeName>/bindirectory.

    This will set the JVM properties only for that particular AppNode.

It is important to understand how JVM parameters at different levels impact the AppNodes in the environment. This has been explained with the help of use cases in the sections below.
