This Vuser already started a transaction with the same name...解决方法

 在做性能测试的时候，有时候会遇到下面的错误：

This Vuser already started a transaction with the same name, and has not yet processed the corresponding lr_end_transaction statement.

解释：就是脚本中有一个事物开始了，但是没有结束事物，此时loadrunner就会报错，因为开始和结束是一一对应的，谁也不能把它们拆开，拆开了就会报错。

查看脚本如下：

import java.lang.String;
import java.rmi.Naming; 
import java.util.*;
import lrapi.lr;
import com.paic.pafa.app.biz.ac.impl.ApplicationControllerBean;

import com.paic.pafa.app.lwc.core.beans.BeansException;

public class Actions

       public int init() throws Throwable {
       DummyClassLoader.setContextClassLoader();
       com.paic.pafa.app.biz.ac.impl.ApplicationControllerHome home = null;
      try{
     java.util.Properties p = new java.util.Properties();
     p.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
     p.put(javax.naming.Context.PROVIDER_URL, "");

        } catch (javax.naming.NamingException e) {
     e.printStackTrace();
 }
     try {
  lr.start_transaction("appctrlhome_create");
  remote = home.create();
  lr.end_transaction("appctrlhome_create", lr.AUTO);
     } catch (Throwable t) {

  t.printStackTrace();
     }
     return 0;
 }

 public int action(){
     ServiceResponse serviceResponse = null;
     ServiceRequest serviceRequest = new ServiceRequest();

     outMap.putAll(msgHeadmap);
     outMap.putAll(msgbodyMap);
        
    
     serviceRequest.setCurrentRequestObject(outMap);
     serviceRequest.setRequestedServiceID("dispatchAction");

     lr.think_time(15);
 
     try {
     lr.start_transaction("电信局_后台扣费");
      serviceResponse = remote.handleRequest(serviceRequest);
     
      responseMap = (Map)serviceResponse.getModel();
      resultMap=(Map)responseMap.get(ServiceResponse.SERVICE_RESPONSE_RESULT);
      headMap = (Map)resultMap.get("MSG_HEAD");
      resultCode = (String)headMap.get("RESULT_CODE"); //结果代码 写在头部信息里
      resultMsg = (String)headMap.get("RESULT_MESSAGE"); //结果代码 写在头部信息里
  if (resultCode.equals("0000")) {
  lr.end_transaction("电信局_后台扣费",lr.PASS); 
     }
     else {
  lr.end_transaction("电信局_后台扣费",lr.FAIL);
     }

     } catch (Throwable t) {
      t.printStackTrace();
     }

    
     lr.message(resultCode);
  
     return 0;
 }//end of action
   

 public int end() throws Throwable {
  return 0;
 }

}

 

分析：由于错误提示是transaction ，所以主要看插入事物的脚本部分，根据提示可以断定，程序在进入lr.start_transaction后，在end_transaction前就异常了，所以并没有执行end_transaction，就会报这个错误，这个分析可能一时难以想到，还有一种简单的办法，就是执行脚本，然后看Replay Log，此时可以看到一个红色的异常，内容如下：Error: Vuser started transaction "电信局_后台扣费", but did not reached a corresponding end transaction statement. The transaction ended automatically with status 'fail'.

根据这个就很容易判断了。

解决办法：

根据上面的分析，此脚本的容错性很差，修改只要把事物的开始和结束放到try的外面即可，脚本如下：

import java.lang.String;

     Object homeobj = ic.lookup("ejb/bib/PafaAC");
     home = (com.paic.pafa.app.biz.ac.impl.ApplicationControllerHome)javax.rmi.PortableRemoteObject.narrow(homeobj, com.paic.pafa.app.biz.ac.impl.ApplicationControllerHome.class);
        } catch (javax.naming.NamingException e) {
     e.printStackTrace();
 }
     try {
  lr.start_transaction("appctrlhome_create");
  remote = home.create();
  lr.end_transaction("appctrlhome_create", lr.AUTO);
     } catch (Throwable t) {
  lr.end_transaction("appctrlhome_create", lr.FAIL);
  t.printStackTrace();
     }
     return 0;
 }

 public int action(){
     ServiceResponse serviceResponse = null;
     ServiceRequest serviceRequest = new ServiceRequest();

    Map responseMap = new HashMap();
    Map resultMap = new HashMap();
    Map headMap = new HashMap();

     msgbodyMap_in.put("TOLAMT","0.01");            //总扣费额TOLAMT           
         
     msgbodyMap.put("MSG_BODY",msgbodyMap_in);

     Map outMap = new HashMap();
     outMap.putAll(msgHeadmap);
     outMap.putAll(msgbodyMap);
        
    
     serviceRequest.setCurrentRequestObject(outMap);
     serviceRequest.setRequestedServiceID("dispatchAction");

     lr.think_time(15);
     lr.start_transaction("电信局_后台扣费");
     try {
    
      serviceResponse = remote.handleRequest(serviceRequest);
     
      responseMap = (Map)serviceResponse.getModel();
      resultMap=(Map)responseMap.get(ServiceResponse.SERVICE_RESPONSE_RESULT);
      headMap = (Map)resultMap.get("MSG_HEAD");
      resultCode = (String)headMap.get("RESULT_CODE"); //结果代码 写在头部信息里
      resultMsg = (String)headMap.get("RESULT_MESSAGE"); //结果代码 写在头部信息里
  

     } catch (Throwable t) {
      t.printStackTrace();
     }
     if (resultCode.equals("0000")) {
  lr.end_transaction("电信局_后台扣费",lr.PASS); 
     }
     else {
  lr.end_transaction("电信局_后台扣费",lr.FAIL);
     }
    
     lr.message(resultCode);
  
     return 0;
 }//end of action
   

 public int end() throws Throwable {
  return 0;
 }

}

 

此时运行的时候就不会有这种错误提示了，问题得到解决。
