Graceful shutdown of a webMethods Integration Server through custom developed java program

Out of the box a webMethods Integration Server is shutdown via the Administrator screen.

Following code snippet with allow you to gracefully shutdown a webMethods Integration Server through the usage of a custom developed java program.

Java code snippet :
import java.io.*;
import com.wm.app.b2b.client.*;
import com.wm.util.*;
import com.wm.data.*;

public class IntegrationServerShutdown
{
            public String hostName = null;
            public String port = null;
            public String userName = null;
            public String password = null;
            Context context = null;
            public boolean connected = false;
            public static void main(String[] args)
            {           String input = null;
                        //Create an instance of a b2bServer
                        IntegrationServerShutdown b2bServer = new IntegrationServerShutdown();

                        b2bServer.hostName=args[0];
                        b2bServer.port=args[1];
                        b2bServer.userName=args[2];
                        b2bServer.password=args[3];
                        System.out.println("");
                        b2bServer.connect();
                        if(!b2bServer.connected)
                                    System.exit(0);
                        b2bServer.shutdown();

            }
            public void connect()
            {           context = new Context();
                        try
                        {           context.connect(hostName + ":" + port, userName, password);
                                    System.out.println("Connected to " + hostName + ":" + port);
                                    connected = true;
                        }
                        catch(ServiceException e)
                        {           System.out.println("Could not connect to " + hostName + ":" + port);
                                    System.out.println(e.toString());
                                    connected = false;
                        }
            }
            public void disconnect()
            {           if(context != null)
                                    context.disconnect();
            }
            public void shutdown()
            {           try
                        {
                                    System.out.println("Shutting down IS Server... ");
                                    IData inputs = IDataFactory.create();
                                    IDataCursor myCursor = inputs.getCursor();
                                    myCursor.insertAfter("bounce", "no");
                                    myCursor.insertAfter("timeout", "0");
                                    myCursor.insertAfter("option", "force");
                                    context.invoke("wm.server.admin","shutdown",inputs);
                                    System.out.println("IS Server shutdown complete.");
                                    System.exit(0);
                        }
                        catch(ServiceException e)
                        {           System.out.println("IS Server shutdown failed.");
                                    System.out.println(e.toString());
                                    System.exit(1);
                        }
            }

}

Remarks :

  1. When compiling and running the java program make sure to include files wm-isclient.jar and mail.jar in your class path. File wm-isclient.jar can found in the “common/lib” folder of an Integration Server whereas file mail.jar is localized in the “ext” sub folder of the “common/lib” folder.
  2. Usage of the IntegrationServerShutdown program is IntegrationServerShutdown <IS hostname> <IS port> <IS account with administrative privileges> <IS account password>
  3. At this moment the java program is working with at least webMethods Integration Server v7.1.2 and v8.2. Specifications contained herein are potentially subject to change so use them at your own risk.
