1. 应用场景

当运行很久的Job突然出现性能问题时，并排除数据量突然变大，可能原因有执行的脚本的某些对应的SQL的解析计划变更

2. 解决步骤

Step1. 通过对应的User或者其他信息查找Session ID

Step2. 通过Session_ID查看该SQL_ID历史的解析计划变换

Step3. 如果最近发生解析计划变更，并导致效率变慢，通过SPM绑定之前的解析计划

Step4. 确定解析计划是否绑定

Step5. 如果脚本还在运行，让客户停掉脚本，并重新运行，以测试绑定的新的解析计划是否满足期望

Step6. 如果绑定的解析计划并不能解决性能问题，验证后将其删除

---

Step1. 通过对应的User或者其他信息查找Session ID

select sql_id, username, osuser, machine, program
  from v$session
 where username = 'gavin'

Step2. 查看该SQL_ID历史的解析计划变换

select distinct a.instance_number,
                trunc(b.begin_interval_time, 'mi'),
                sql_id,
                plan_hash_value
  from dba_hist_sqlstat a, dba_hist_snapshot b
 where a.snap_id = b.snap_id
   and sql_id = '089dbukv1aanh'
 order by 2, 1

Step3. 如果最近发生解析计划变更，并导致效率变慢，通过SPM绑定之前的解析计划 (脚本coe_xfr_sql_baseline.sql)

Step4. 确定解析计划是否绑定

select sql_handle, plan_name, sql_text, creator, description, enabled, accepted, fixed
  from dba_sql_plan_baselines
 where description like '%089dbukv1aanh%'

Step5. 如果脚本还在运行，让客户停掉脚本，并重新运行，以测试绑定的新的解析计划是否满足期望

alter system disconnect session '102,102' immediate; 

Step6. 如果绑定的解析计划并不能解决性能问题，验证后将其删除

REM SCRIPT
REM   coe_xfr_sql_baseline.sql
REM
REM DESCRIPTION
REM   This script loads a plan from AWR into the SQL
REM   Plan Baseline of the specified SQL.
REM
REM PRE-REQUISITES
REM   1. Have in AWR the text for the specified SQL.
REM
REM PARAMETERS
REM   1. SQL_ID (required)
REM   2. PLAN_HASH_VALUE in AWR (required)
REM
REM EXECUTION
REM   1. Connect into SQL*Plus as user with access to data dictionary
REM      and privileges to create SQL Plan Baselines. Do not use SYS.
REM   2. Execute script coe_xfr_sql_baseline.sql passing first two
REM      parameters inline or until requested by script.
REM
REM EXAMPLE
REM   # sqlplus system
REM   SQL> START coe_xfr_sql_baseline.sql gnjy0mn4y9pbm b8f3mbkd8bkgh
REM   SQL> START coe_xfr_sql_baseline.sql;
REM
REM NOTES
REM   1. This script works on 11g or higher.
REM   2. For a similar script for 10g use coe_xfr_sql_profile.sql,
REM      which uses custom SQL Profiles instead of SQL Baselines.
REM   3. For possible errors see coe_xfr_sql_baseline.log
REM   4. Use a DBA user but not SYS. Do not connect as SYS as the staging
REM      table cannot be created in SYS schema and you will receive an error:
REM      ORA-19381: cannot create staging table in SYS schema
