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。有关PL/SQL Profiler的文章可以参考：使用 DBMS_PROFILER 定位 PL/SQL 瓶颈代码对比 PL/SQL profiler 剖析结果使用PL/SQL Developer剖析PL/SQL代码

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.
