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 You may choose from list provided or enter a valid phv
REM from a version of the SQL modified with Hints.
REM
REM EXECUTION
REM 1. Connect into SQL*Plus as user with access to data dictionary.
REM Do not use SYS.
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.
REM 4. Use a DBA user but not SYS.
REM 5. If you get "ORA-06532: Subscript outside of limit, ORA-06512: at line 1"
REM Then you may consider this change (only in a test and disposable system):
REM create or replace TYPE sys.sqlprof_attr AS VARRAY(5000) of VARCHAR2(500);
