Creating Java virtual machines for WebSphere® Application Server

When you create a Java™ virtual machine (JVM), you can set the parameter and memory settings.

Procedure

  1. Open the Integrated Solutions Console http://servername:9060/admin and log in.
  2. In the navigation pane, click Servers > New server.
  3. Click WebSphere application server and click Next.
  4. Specify the server name and click Next.
  5. Accept the default values for the server template and click Next.
  6. Accept the default values for the server properties and click Next.
  7. Click Finish, click Save, and then click OK.
  8. Edit JVM memory settings and parameters:
    1. Click Servers and then click the server you created.
    2. Under Service Infrastructure, click Java and Process Management > Process definition > Java Virtual Machine.
    3. Scroll down and type 1536 for Initial Heap Size and 4096 for Maximum Heap Size.
    4. In the Generic JVM arguments field, use the JVM parameter -Dmxe.name=hostname~jvmname to name each server. -Dmxe.name is the property name passed to the JVM at startup time and hostname~jvmname is the name that you identify as the JVM server. With this information, when you look at the log file, a donotrun parameter, or a maxsession entry, you can identify the JVM.

      For example, -Dmxe.name=computer1~uiserver1

  9. Set the new application server to start in running mode:
    1. Click Servers and then click the server you created.
    2. Click Java and Process Management > Monitoring policy.
    3. Change the Node restart state to RUNNING.
    4. Click Apply and then click Save.
