离线运行Oracle Database In-Memory Advisor
2023-12-13 06:02:55
概念
离线运行Oracle Database In-Memory Advisor，就是不在生产系统上运行。这样可以避免影响生产系统。但需要从生产系统导出以下的数据：
- AWR Dump
- AWR补充数据
过程
导出AWR Dump
连接到CDB root运行。
SQL> connect / as sysdba
SQL> @?/rdbms/admin/awrextr.sql

AWR EXTRACT
~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~ This script will extract the AWR data for a range of snapshots ~
~ into a dump file. The script will prompt users for the ~
~ following information: ~
~ (1) database id ~
~ (2) snapshot range to extract ~
~ (3) name of directory object ~
~ (4) name of dump file ~

导出AWR补充数据
导出AWR Dump后，应马上运行导出AWR补充数据。
也是连接到CDB root运行：
SQL> connect / as sysdba
SQL> @/home/oracle/imadvisor/imadvisor_awr_augment_export.sql
********************************************************************************
* This script will create for you an Automatic Workload Repository (AWR)
* augment that will supply additional data required by the Oracle Database
* In-Memory Advisor. Without this data augment, you cannot use an AWR export
* with the In-Memory Advisor. (But with it, you can!)
*
* Note: The Automatic Workload Repository (AWR) augment you are about to create
* can only be used with an AWR export from this local database
* (DBID=1677860020).
*
* Also note: It is best to capture an AWR augment in the same timeframe
* (preferably after) the corresponding AWR export.
********************************************************************************
You may optionally include one the following SQL Tuning Set(s) as part of the
AWR augment.
Enter the sqlset_owner and sqlset_name in the prompts below to include a SQL

运行In-Memory Advisor
SQL> imadvisor_recommendations
SP2-0734: unknown command beginning "imadvisor_..." - rest of line ignored.
SQL> @imadvisor_recommendations
This script creates and runs an In-Memory Advisor task that analyzes
your workload to determine an optimal In-Memory configuration.
This script then generates an HTML recommendation report file in the
current working directory: imadvisor_<task_name>.html
This script also generates a sqlplus DDL script to implement the
recommendations: imadvisor_<task_name>.sql
NOTE: You may specify one of your existing tasks if you wish to optimize for a
different In-Memory size.
Using an existing, executed task is faster than a new task since a new task
requires statistics gathering and analysis.
But if you wish to analyze a different workload or use a different statistics
capture window or add a SQLSET, you must specify a new task.
The following is a list of your existing tasks:
TASK_NAME DATE_CREATED
------------------------------ -----------------------------
im_advisor_task_20231212034203 2023-DEC-12 03:42:32

Enter value for task_name:
Advisor task name specified: im_advisor_task_20231212035008 (default)
New Advisor task will be named: im_advisor_task_20231212035008...
By default, the Advisor runs against a live workload on this database.
This database also has imported, augmented AWR workloads.
Press ENTER or respond NO to run against a live workload.
Respond YES to run against an augmented AWR workload.
Enter value for run_against_augmented_awr: YES
The Advisor can use the following augmented AWR imports:
Augmented AWR Import DBID
-------------------------
1677860020
Enter value for dbid: 1677860020

The In-Memory Advisor optimizes the In-Memory configuration for a specific
In-Memory size that you choose.
After analysis, the In-Memory Advisor can provide you a list of performance
benefit estimates for a range of In-Memory sizes. You may then choose the
In-Memory size for which you wish to optimize.
If you already know the specific In-Memory size you wish, please enter
the value now. Format: nnnnnnn[KB|MB|GB|TB]
Or press <ENTER> to get performance estimates first.
Enter value for inmemory_size: 10G
The In-Memory Advisor will optimize for this In-Memory size: 10G
Enter begin time for report:
-- Valid input formats:
-- To specify absolute begin time:
-- [MM/DD[/YY]] HH24:MI[:SS]
-- Examples: 02/23/03 14:30:15
-- 02/23 14:30:15
-- 14:30:15
-- 14:30
-- To specify relative begin time: (start with '-' sign)
-- -[HH24:]MI
-- Examples: -1:15 (SYSDATE - 1 Hr 15 Mins)
-- -25 (SYSDATE - 25 Mins)
Default begin time: 12/10/23 18:00:44
Enter value for begin_time:
Report begin time specified:
Enter duration in minutes starting from begin time:
(defaults to <latest-snapshot-end-time> - begin_time)
Enter value for duration:
Report duration specified:
Using 2023-DEC-10 18:00:44.000000000 as report begin time
Using 2023-DEC-11 05:00:07.000000000 as report end time
You may optionally specify a comma separated list of object owner
and name patterns to be considered for In Memory Placement.
Example:
GEEK_SUMMARY.%,%.GEEK_%
Press ENTER to consider all objects.
Enter value for consider_objects_like:
Considering all objects for In Memory placement.
