Oracle – ILM

admin 11月 12, 2020 0

ILM is mean Information Lifecycle Management. It’s practice of applying policies for effective management of information throughout its useful life.

Implementing ILM Using Oracle Database
The offical documentation see here

And mainly four steps:

Define the Data Classes

Create Storage Tiers for the Data Classes

Create Data Access and Migration Policies

Define and Enforce Compliance Policies

In fact, in our production, I need to handle a unpartition table to ILM, so I should archive data and create partition and add customize policy.
See the below steps:

Archive Database

@IBSArch.par
set serveroutput on;
set verify off;

spool IBSArchive.log
