Example: Configuring the Java virtual machine using wsadmin

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()
