REM

REM SCRIPT

REM coe_xfr_sql_profile.sql

REM

REM DESCRIPTION

REM This script generates another that contains the commands to

REM create a manual custom SQL Profile out of a known plan from

REM memory or AWR. The manual custom profile can be implemented

REM into the same SOURCE system where the plan was retrieved,

REM or into another similar TARGET system that has same schema

REM objects referenced by the SQL that generated the known plan.

REM

REM PRE-REQUISITES

REM 1. Oracle Tuning Pack license.

REM

REM PARAMETERS

REM 1. SQL_ID (required)

REM 2. Plan Hash Value for which a manual custom SQL Profile is

REM needed (required). A list of known plans is presented.

REM

REM EXECUTION

REM 1. Connect into SQL*Plus as SYSDBA or user with access to

REM data dictionary.

REM 2. Execute script coe_xfr_sql_profile.sql passing SQL_ID and

REM plan hash value (parameters can be passed inline or until

REM requested).

REM

REM EXAMPLE

REM # sqlplus system

REM SQL> START coe_xfr_sql_profile.sql [SQL_ID] [PLAN_HASH_VALUE];

REM SQL> START coe_xfr_sql_profile.sql gnjy0mn4y9pbm 2055843663;

REM SQL> START coe_xfr_sql_profile.sql gnjy0mn4y9pbm;

REM SQL> START coe_xfr_sql_profile.sql;

REM

REM NOTES

REM 1. For possible errors see coe_xfr_sql_profile.log

REM 2. If SQLT is installed in SOURCE, you can use instead:

REM sqlt/utl/sqltprofile.sql

REM 3. Be aware that using DBMS_SQLTUNE requires a license for

REM Oracle Tuning Pack.
