Enabling IBM Technology for 32-bit Java Virtual Machines

Note: WebSphere Application Server Network Deployment 7.0 is supported with V6R1 and V5R4 only. EnterpriseOne supports IBM Technology for Java (32-bit JVM) with WebSphere Application Server 7.0. and Classic JVM (64-bit JVM) is also supported with EnterpriseOne and WebSphere Application Server 7.0.

Classic JVM (64-bit JVM) is the default configuration for WebSphere v7.0 on V6R1 and V5R4 i5/OS. Use the steps below to switch to IBM Technology for Java (32-bit JVM)

To enable IBM technology for java (J9 JVM – 32 bit JVM on i5/OS) support:

  1. Stop all the WebSphere server processes.

  2. Stop this WebSphere 7 subsystem:

    QWAS7

  3. Open QShell using this command:

    STRQSH

  4. Change the directory using this command:

    cd /QIBM/PRODDATA/WebSphere/AppServer/v7/ND/bin

  5. Enter this command:

    ./enableJVM -jvm std32

    Once the command completes successfully the following message is displayed, which indicates that the 32-bit J9 JVM is enabled for all the profiles within WebSphere:
