This topic contains the following tasks:

• Tracing operations using wsdmin.sh
  

• Configure traces
  

• Turning traces on and off in servers processes
  

• Dumping threads in server processes
  

• Set up profile scripts to make tracing easier
  

• Enable the Runtime Performance Advisor tool
  

Example

We can set the trace string using either of the following supported formats. For example:

$AdminControl trace com.ibm.*=all=enabled

or

$AdminControl trace com.ibm.*=all

For more instructions, see the tracing and logging information. To set the log level, see the log level settings information.

Subtopics

• Tracing operations using wsdmin.sh
  We can enable and disable tracing and wsadmin.sh.

• Extracting properties files to troubleshoot the environment
  Use this topic to create a properties file that displays configuration information for a node, application server, application, or other resource. We can use this file to troubleshoot a problem in the environment.

• Configure traces
  Use wsadmin.sh and scripting to configure traces for a configured server.

• Turning traces on and off in servers processes
  We can use scripting to turn traces on or off in server processes.

• Dumping threads in server processes
  Use the AdminControl object to produce a Java core dump, which includes the Java threads of a running server.

• Set up profile scripts to make tracing easier
  We can use scripting and wsadmin.sh to set up profile scripts to facilitate tracing.

• Enable the Runtime Performance Advisor tool
  We can configure the Runtime Performance Advisor (RPA) or the console.

• AdministrationReports (AdminTask)
  We can use the Jython or Jacl scripting languages to troubleshoot your configuration with wsadmin.sh. The commands in the AdministrationReports group can be used to create a report of inconsistencies in the system configuration or a report that describes the port usage in the system.

• Configure HPEL with wsadmin scripting
  We can configure the High Performance Extensible Logging (HPEL) log and trace framework . Use the examples in this topic as a guide to build our own wsadmin scripts.
