Shulou(Shulou.com)05/31 Report--

This article introduces the relevant knowledge of "how to use manual type sql_profile". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Automatic type of sql_profile (using dbms_sqltune)

The experiments are as follows:

SQL > create table T1 (n number)

Table created.

SQL > declare

Begin

For i in 1..10000 loop

Insert into T1 values (I)

Commit

End loop

End

PL/SQL procedure successfully completed.

SQL > select count (*) from T1

COUNT (*)

10000

SQL > create index idx_t1 on T1 (n)

Index created.

SQL > analyze table T1 compute statistics

Table analyzed.

SQL > select / * + no_index (T1 idx_t1) * / * from T1 where nasty 1

one

SQL > set lines 200

SQL > select * from table (dbms_xplan.display_cursor (null,null,'advanced'))

FINDINGS SECTION (1 finding)

1-SQL Profile Finding (see explain plans section below)

DBMS_SQLTUNE.REPORT_TUNING_TASK ('MY_SQL_TUNING_TASK_2')

A potentially better execution plan was found for this statement.

Recommendation (estimated benefit: 90.91%)

-Consider accepting the recommended SQL profile.

Execute dbms_sqltune.accept_sql_profile (task_name = >

'my_sql_tuning_task_2', task_owner = >' SYS', replace = > TRUE)

Validation results

The SQL profile was tested by executing both its plan and the original plan

DBMS_SQLTUNE.REPORT_TUNING_TASK ('MY_SQL_TUNING_TASK_2')

And measuring their respective execution statistics. A plan may have been

Only partially executed if the other could be run to completion in less time.

REM This script is generated by coe_xfr_sql_profile.sql

REM It contains the SQL*Plus commands to create a custom

REM SQL Profile for SQL_ID c4j6hxkqudj1s based on plan hash

REM value 3617692013.

REM The custom SQL Profile to be created by this script

REM will affect plans for SQL commands with signature

REM matching the one for SQL Text below.

REM Review SQL Text and adjust accordingly.

REM

REM PARAMETERS

REM None.

REM

REM EXAMPLE

REM SQL > START coe_xfr_sql_profile_c4j6hxkqudj1s_3617692013.sql

REM NOTES

REM 1. Should be run as SYSTEM or SYSDBA.

REM 2. User must have CREATE ANY SQL PROFILE privilege.

REM 3. SOURCE and TARGET systems can be the same or similar.

REM 4. To drop this custom SQL Profile after it has been created:

REM EXEC DBMS_SQLTUNE.DROP_SQL_PROFILE ('coe_c4j6hxkqudj1s_3617692013')
