Trace file（追踪文件)是以trc为后续的文本文件,它记录了各种sql操作及所消耗的时
间等,根据trace文件我们就可以了解哪些sql导致了系统的性能瓶颈，进而采取恰当的
方式调优.
查询生产报表—所有制程的WIP；
show parameter sql_trace;
（如果value是false表示系统当前不会产生trace文件.采取如下操作让系统产生trace
文件。）
alter session set sql_trace=true;
EXEC DBMS_MONITOR.DATABASE_TRACE_ENABLE(true, true);
EXEC DBMS_MONITOR.DATABASE_TRACE_DISABLE();
（开启数据库级的trace，目的是为了跟踪SQL。）
利用everything搜索.trc找到Trace file。
udump中一般放置sql trace之后session的trace文件，按时间排列找打最近生成
的.trc文件，用notpad++打开，查找对应SQL语句，把值替换到SQL语句中，在
PLSQL Developer执行SQL语句。
