我写了一个tuxedo程序，bug出在客户端，很可能出在与Oracl交互的地方，我想在相关地方进行调试，在与数据库连通前后的地方加入了几条uesrlog语句(头文件已经包含userlog.h)：
   userlog("\nTest1\n";
   EXEC SQL WHENEVER SQLERROR DO sqlerror();
   userlog("\nTest2\n";
   EXEC SQL CONNECT :username IDENTIFIED BY :password;
   userlog("\nConnected to ORACLE as user:%s\n",username.arr);

发现只有中间一条出现在ULOG*文件中:

1.不可能的，再grep下chkitemsvr
2.用Tuxedo相关的debug可以打开TMTRACE
3.在用户端加ulog是最可靠的
