Setting up profile scripts to make tracing easier using wsadmin scripting

You can use scripting and the wsadmin tool to set up profile scripts to facilitate tracing.

Before you begin

Before starting this task, the wsadmin tool must be running. See Starting the wsadmin scripting client using wsadmin scripting for more information.

Procedure

Set up a profile script to make tracing easier. The following profile script example turns tracing on and off for server1:

Using Jacl:

proc ton {} {
  global AdminControl
  set ts [$AdminControl queryNames type=TraceService,node=mynode,process=server1,*]
  $AdminControl setAttribute $ts traceSpecification com.ibm.=all=enabled
} 

proc toff {} {
  global AdminControl
  set ts [$AdminControl queryNames type=TraceService,node=mynode,process=server1,*]
  $AdminControl setAttribute $ts traceSpecification com.ibm.*=all=disabled
} 

proc dt {} {
  global AdminControl
  set jvm [$AdminControl queryNames type=JVM,node=mynode,process=server1,*]
  $AdminControl invoke $jvm dumpThreads 
}

Using Jython:

def ton():
       global lineSeparator
       ts = AdminControl.queryNames('type=TraceService,node=mynode,process=server1,*')

       AdminControl.setAttribute(ts, 'traceSpecification', 'com.ibm.=all=enabled')

def toff():
       global lineSeparator
       ts = AdminControl.queryNames('type=TraceService,node=mynode,process=server1,*')

       AdminControl.setAttribute(ts, 'traceSpecification', 'com.ibm.*=all=disabled')

def dt():
       global lineSeparator
       jvm = AdminControl.queryNames('type=JVM,node=mynode,process=server1,*')
       AdminControl.invoke(jvm, 'dumpThreads')

Note: The dumpThreads command creates other types of dump files depending on the -Xdumps settings. Dump output varies depending on the platform and might include system core files, heap, and snap dumps.

If you start the wsadmin tool with this profile script, you can use the ton command to turn on tracing in the server, the toff command to turn off tracing, and the dt command to dump the Java threads.
