REM REM AUTHOR REM [e-mail] 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).
