Weblogic 10.3.5: Enable Debugging Using the WebLogic Scripting Tool WLST Scripts and WLST from Java


Weblogic 10.3.5: Enable Debugging Using the WebLogic Scripting Tool  WLST Scripts and WLST from Java

WebLogic Scripting Tool (WLST) can be used to set the debugging values. For example, the following command runs a program for setting debugging values called debug.py:
java weblogic.WLST debug.py
The main scope, weblogic, does not appear in the graphic; jms is a sub-scope within weblogic. Note that the fully-qualified DebugScope for DebugJMSBackEnd is weblogic.jms.backend.
The debug.py program contains the following code:
user='user1'
password='password'
url='t3://localhost:7001'
connect(user, password, url)
edit()
cd('Servers/myserver/ServerDebug/myserver')
startEdit()
set('DebugJMSBackEnd','true')
save()
activate()
Note that you can also use WLST from Java. The following example shows a Java file used to set debugging values:
import weblogic.management.scripting.utils.WLSTInterpreter;
import java.io.*;
import weblogic.jndi.Environment;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;

public class test {
  public static void main(String args[]) {
 try {
  WLSTInterpreter interpreter = null;
  String user="user1";
  String pass="pw12ab";
  String url ="t3://localhost:7001";
  Environment env = new Environment();
  env.setProviderUrl(url);
  env.setSecurityPrincipal(user);
  env.setSecurityCredentials(pass);
  Context ctx = env.getInitialContext();

  interpreter = new WLSTInterpreter();
  interpreter.exec
   ("connect('"+user+"','"+pass+"','"+url+"')");
  interpreter.exec("edit()");
  interpreter.exec("startEdit()");
  interpreter.exec
   ("cd('Servers/myserver/ServerDebug/myserver')");
  interpreter.exec("set('DebugJMSBackEnd','true')"); 
  interpreter.exec("save()");
  interpreter.exec("activate()");

 } catch (Exception e) {
 System.out.println("Exception "+e);
 }
 }
}
Using the WLST is a dynamic method and can be used to enable debugging while the server is running.
