PL/SQL Profiler 剖析报告生成html
使用图形化界面工具实施PL/SQL Profiler 易用直观，但是并不是所有的环境都可以使用图形界面软件连接到数据库。对于只能在命令行下进行剖析又需要直观呈现剖析结果的情形，Oracle为我们提供了脚本来直接生成html文档。本文即是基于这种情形进行演示并加以说明。
1、实施PL/SQL Profiler步骤
–下面的步骤直接参考了Metalink文档(ID 243755.1)
a、If needed, create the PL/SQL Profiler Tables under your application schema: @?/rdbms/admin/proftab.sql
b、If needed, install the DBMS_PROFILER API, connected as SYS: @?/rdbms/admin/profload.sql
c、Start PL/SQL Profiler in your application: EXEC DBMS_PROFILER.START_PROFILER(‘optional comment’);
d、Execute your transaction to be profiled. Calls to PL/SQL Libraries are expected.
e、Stop PL/SQL Profiler: EXEC DBMS_PROFILER.STOP_PROFILER;
f、Connect as your application user, execute script profiler.sql provided in this document: @profiler.sql
g、Provide to profiler.sql the “runid” out of a displayed list.
h、Review HTML report generated by profiler.sql.
2、演示PL/SQL Profiler
- –由于我们已经配置好了Profiler，因此下面直接进行剖析
- a、开始Profiler
- XXX_ADMIN@SYBO2> EXEC DBMS_PROFILER.START_PROFILER(‘PREPARE TRADE TBL ‘);
- PL/SQL procedure successfully completed.
- b、执行需要剖析的过程
- XXX_ADMIN@ORAID> DECLARE
- 2 TRADE_DATE_IN VARCHAR2(32767);
- 3 ERR_NUM NUMBER;
- 4 ERR_MSG VARCHAR2(32767);
- 5
- 6 BEGIN
- 7 TRADE_DATE_IN := ‘20130911’;
- 8 ERR_NUM := NULL;
- 9 ERR_MSG := NULL;
- 10
- 11 XXX_ADMIN.XXX_GEN_DTL_PKG.PREPARE_TRADE_DTL_TBL ( TRADE_DATE_IN, ERR_NUM, ERR_MSG );
- 12 COMMIT;
- 13 END;
- 14 /
- PL/SQL procedure successfully completed.
- c、停止profiler
- XXX_ADMIN@ORAID> EXEC DBMS_PROFILER.STOP_PROFILER;
- PL/SQL procedure successfully completed.

- d、生成Profiler报告
- XXX_ADMIN@ORAID> @profiler
- RUNID RUN_OWNER RUN_DATE RUN_COMMENT
- —— ————————- ————— ——————————
- 3 XXX_ADMIN 29-SEP-13 11:53 PREPARE TRADE TBL
- Parameter 1:
- RUNID (required)
- Enter value for 1: 3 —>输入对应的Profiler的运行ID
- Value passed:
- ~~~~~~~~~~~~
- RUNID: “3”
- PROFILER file has been created:
- profiler_SID_xxxxxdb01uv_10.2.0.3.0_20130929_115525.html.
