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：

  1. AWR Dump
  2. 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                                        ~

以上一般为用户执行，会生成2个dump文件；然后将这两个文件给到DBA，就可以执行下面的导入和分析了。

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：

* 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

运行In-Memory Advisor


SQL> imadvisor_recommendations
SP2-0734: unknown command beginning "imadvisor_..." - rest of line ignored.
SQL> @imadvisor_recommendationsThis 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>.htmlThis script also generates a sqlplus DDL script to implement the
recommendations: imadvisor_<task_name>.sqlNOTE: 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

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: YESThe Advisor can use the following augmented AWR imports:Augmented AWR Import DBID

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.

错误处理

在导入AWR dump时，可能出现错误，原因是目标端的数据库不兼容，并非是源数据库导出数据的问题：
