Oracle 11g 生产大量的Trace 文件

#打开10046事件，一下列方式
SQL> alter system set event='10046 trace name context forever,level 12' scope=spfile;

#关闭10046
SQL> alter system set event='10046 trace name context forever,level 0' scope=spfile;

#重启数据库，发现还是产生大量的trace文件
[oracle@hzvscmdb trace]$ pwd
/home/oracle/app/oracle/diag/rdbms/tonytest/tonytest/trace
[oracle@hzvscmdb trace]$ ls -l | grep '^-' | wc -l
1143

#查看sql_trace是否为False
SQL> show parameter trace
