一. This Vuser already started a transaction with the same name, and has not yet processed the corresponding lr_end_transaction statement.
  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:是脚本中有一个事物开始了,但是没有结束事物,此时loadrunner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,拆开了会报错。
  异常再现:
  下列代码中,如果业务方法报了异常(Throw Exception),那么下面的if判断的代码不会被执行,而直接跳到catch子句里,那么已经开始的业务"searchItemList_man"没有被结束,当你再次开始业务时,会报错~
1 public int action() throws Throwable {
2
3         misc = generateManItemSearchCondition();
4                 lr.start_transaction("searchItemList_man");
5         try {
6             //业务方法
7             items = searchService.searchItemList(misc);
8             if (items.isSuccess()) {
9                 lr.end_transaction("searchItemList_man",lr.PASS);
10
11             } else {
12                 lr.end_transaction("searchItemList_man",lr.FAIL);
13             }
14             orderMap.clear();
15             productIdSet.clear();
16             productStatusList.clear();
17         } catch (Exception e) {
18
19
20             e.printStackTrace();
21         }
22
23
24         misc = null;
25         items = null;
26         return 0;
27     }//end of action
  解决办法:  在catch字句里加上一个 事务结束代码,修改后的catch段代码如下:
catch (Exception e) {
// TODO Auto-generated catch block
lr.end_transaction("searchItemList_man",lr.FAIL);
e.printStackTrace();
}
