My Definition of Cloning…

The process of reproducing an entire environment,including the Oracle home ($ORACLE_HOME)and Application top ($APPL_TOP) directorystructures.

Note that this may be different than what youcurrently now as “refreshing” a database.

Cloning 11i Instances

Two Methods:

§ Manually - Need To Change

- Dozens Of Configuration Files

- Numerous Site Profile Values

- Not Supported

§ Oracle’s adclone.pl

Cloning 11i Instances

adclone.pl:

§ MetaLink Document: 280896 / Patch 1636653

§ A Supported Method

§ Limitations – Identical Configuration

Overview:

§ Pre-clone, Copy, Post-clone, Wrap-up Tasks

Cloning 11i Instances – adclone.pl
