Oracle DBMS_PROFILER 的使用方式

(一)  安装：

• 用 SYS 身份登录数据库，执行脚本：%ORACLE_HOME% \RDBMS\ADMIN\profload.sql
• 创建一个用于存放信息的 schema， 并授予权限：

CREATE USER profiler IDENTIFIED BY profiler DEFAULT TABLESPACE USERS QUOTA UNLIMITED ON USERS;

GRANT CONNECT, CREATE TABLE, CREATE SEQUENCE TO profiler;

•  用 profiler 身份登录数据库，执行脚本：%ORACLE_HOME% \RDBMS\ADMIN\profload.sql 来创建表和序列，并授予相应权限给 public 角色:

GRANT SELECT ON profiler.plsql_profiler_runnumber TO PUBLIC;

GRANT SELECT, INSERT, UPDATE, DELETE ON profiler.plsql_profiler_runs TO PUBLIC;

GRANT SELECT, INSERT, UPDATE, DELETE ON profiler.plsql_profiler_units TO PUBLIC;

GRANT SELECT, INSERT, UPDATE, DELETE ON profiler.plsql_profiler_data TO PUBLIC;

• 用 SYS 身份登录数据库，为表和序列创建 public 同义词

CREATE PUBLIC SYNONYM plsq_profiler_runnumber FOR profiler.plsql_profiler_runnumber;

CREATE PUBLIC SYNONYM plsql_profiler_runs FOR profiler.plsql_profiler_runs;

CREATE PUBLIC SYNONYM plsql_profiler_units FOR profiler.plsql_profiler_units;

CREATE PUBLIC SYNONYM plsql_profiler_data FOR profiler.plsql_profiler_data;

(二)  使用 DBMS_PROFILER 收集信息:

begin

  -- Call the procedure

  dbms_profiler.start_profiler('profiler');

   FOR i IN 1..10000 LOOP

    EXECUTE IMMEDIATE 'INSERT INTO t VALUES('|| TO_CHAR(i) ||')';

  END LOOP; 

  dbms_profiler.stop_profiler;

end;

可以通过下面SQL查询RUNID:

SELECT runid, run_owner, run_date, run_comment FROM plsql_profiler_runs WHERE run_comment='profiler';

 

(三)  使用 prof.zip 格式化报表： 

SQL> column RUNID format 99

SQL> column RUN_COMMENT format a30

SQL> start "C:\Documents and Settings\Dragon Luo\桌面\prof\profiler.sql"

RUNID RUN_DATE                RUN_COMMENT

----- ----------------------- ------------------------------

    1 20-7月 -12 14:42:42     ora

Usage:

sqlplus apps/<pwd>

SQL> START profiler.sql <runid>

输入 1 的值:  1

生成报表文件profiler_1.html

报表样式见：C:\Documents and Settings\Dragon Luo\桌面\prof\profiler_7.html
