oracle Tkprof 的使用

alter session set max_dump_file_size=unlimited;
alter session set timed_statistics=true;
alter session set events '10046 trace name context forever, level 12';
select 'Hello, world; today is '||sysdate from dual; exit;

tkprof card_ora_13226.trc trace.txt print=100 record=sql.txt sys=no

然后查年trace.txt就是分析内容了
