使用COE脚本绑定SQL Profile

Posted 2021-01-17

日常运维中，经常会遇到需要绑定好的执行计划的场景。

简单来说，就是将一个sql_id绑定好的plan_hash_value。如果没有使用到绑定变量，还需要把force_match设置为true。

用到的是MOS文档215187.1提供的系列脚本中的coe_xfr_sql_profile.sql。

下载地址：coe_xfr_sql_profile.sql.zip

脚本内容具体如下：

SPO coe_xfr_sql_profile.log;
SET DEF ON TERM OFF ECHO ON FEED OFF VER OFF HEA ON LIN 2000 PAGES 100 LONG 8000000 LONGC 800000 TRIMS ON TI OFF TIMI OFF SERVEROUT ON SIZE 1000000 NUMF "" SQLP SQL>;
SET SERVEROUT ON SIZE UNL;

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);
