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.
