Configuring the Java virtual machine using scripting

Why and when to perform this task

An example modifying the Java virtual machine (JVM) of a server to turn on debug follows:
  • Identify the server and assign it to the server1 variable.

    Using Jacl:

    set server1 [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
    Using Jython:
    server1 = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:server1/')
    print server1
    Example output:
    server1(cells/mycell/nodes/mynode/servers/server1|server.xml#Server_1)
  • Identify the JVM belonging to this server and assign it to the jvm variable.

    Using Jacl:

    set jvm [$AdminConfig list JavaVirtualMachine $server1]
    Using Jython:
    jvm = AdminConfig.list('JavaVirtualMachine', server1)
    print jvm
    Example output:
    (cells/mycell/nodes/mynode/servers/server1:server.xml#JavaVirtualMachine_1)
  • Modify the JVM to turn on debug.

    Using Jacl:

    $AdminConfig modify $jvm {{debugMode true} {debugArgs "-Djava.compiler=NONE -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=7777"}}
    Using Jython:
    AdminConfig.modify(jvm, [['debugMode', 'true'], ['debugArgs',  "-Djava.compiler=NONE -Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=7777"]])
  • Save the changes with the following command:

    Using Jacl:

    $AdminConfig save
    Using Jython:
    AdminConfig.save()
