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：
连接到CDB root运行。

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

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 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.
