Oracle 11gR2开始在不执行SQL语句的情况下可以使用dbms_sqldiag.dump_trace来生成10053跟踪文件。它的操作步骤如下:
1.先执行sql语句
SQL> column slq_text format a30
SQL> select sysdate from dual;
SYSDATE
————
15-AUG-14
2.通过sql语句的文本来搜索v$sql找到该语句相应的sql_id.
SQL> select sql_id from v$sql where sql_text like ‘select sysdate from dual%’;
SQL_ID
————-
7h35uxf5uhmm1
3.执行dbms_sqldiag.dump_trace过程来生成10053跟踪文件
SQL> execute dbms_sqldiag.dump_trace(p_sql_id=>’7h35uxf5uhmm1′,p_child_number=>0,p_component=>’Compiler’,p_file_id=>’DIAG’);
PL/SQL procedure successfully completed.
SQL> show parameter user_dump_dest
NAMETYPE VALUE
———————————— ———– ——————————
user_dump_dest string /u01/app/oracle/diag/rdbms/jyc
s/jycs/trace
4.找到生成的10053跟踪文件
SQL> host ls -lrt /u01/app/oracle/diag/rdbms/jycs/jycs/trace/*DIAG*.trc
-rw-r—– 1 oracle oinstall 66194 Aug 15 09:49 /u01/app/oracle/diag/rdbms/jycs/jycs/trace/jycs_ora_8474_DIAG.trc
5.查看10053跟踪文件的内容
SQL> host cat /u01/app/oracle/diag/rdbms/jycs/jycs/trace/jycs_ora_8474_DIAG.trc
Trace file /u01/app/oracle/diag/rdbms/jycs/jycs/trace/jycs_ora_8474_DIAG.trc
