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.
