Tracing operations using wsadmin.sh

We can enable and disable tracing with scripting and wsadmin.

Before starting this task, wsadmin must be running. See the topic about starting wsadmin. Use a trace command to trace operations.

• Enable wsadmin client tracing.

  • Jacl:

    $AdminControl trace com.ibm.*=all

  • Jython:

    AdminControl.trace('com.ibm.*=all')

  where:

  Syntax explanation. Run the trace command with com.ibm.*=all to enable tracing.

  Attribute	Definition
  $	is a Jacl operator for substituting a variable name with its value
  AdminControl	is an object that enables the manipulation of MBeans running in a WebSphere server process
  trace	is an AdminControl command
  com.ibm.*=all	indicates to turn on tracing

• Disable wsadmin client tracing.

  • Jacl:

    $AdminControl trace com.ibm.*=info

  • Jython:

    AdminControl.trace('com.ibm.*=info')

  where:

  Syntax explanation. Run the trace command with com.ibm.*=info to disable tracing.

  Attribute	Definition
  $	is a Jacl operator for substituting a variable name with its value

Results

The trace command changes the trace settings for the current session. We can change this setting persistently by editing the wsadmin.properties file. The property com.ibm.ws.scripting.traceString is read by the launcher during initialization. If it has a value, the value is used to set the trace.

The property com.ibm.ws.scripting.traceString can also be passed in as a javaoption through the command line. Passing the property through the command line changes the trace setting for the current session.

Enable Tracing
wsadmin.sh -javaoption -Dcom.ibm.ws.scripting.traceString=com.ibm.*=all=enabled

A related property, com.ibm.ws.scripting.traceFile, designates a file to receive all trace and logging information. The wsadmin.properties file contains a value for this property. Run wsadmin with a value set for this property. It is possible to run without this property set, where all logging and tracing goes to the dmgr console.
