Oracle Database migration to a remote Data Protector cell--Best practices

4
Figure 1. Test Environment
As mentioned in the opening summary, there maybe different reasons why we need to move a database
to a different data center, different cell, and different location. We mention below the two key ones:
• Data center consolidation
• Disaster Recovery Plan (DRP)
In a data center consolidation scenario, normally downtime and migration time has been agreed
ahead. In case of a disaster, all preparation steps for the DRP need to be done ahead.
Moreover, as the target database, cell and even data center may have been lost, we need to rely on
our existing backups and our target system for the recovery. For this reason, a DRP scenario may
require some more configuration steps.
Target System Preparation
The following subsections list a number of preparation steps that should to be filled up before starting
with the migration procedure. These steps are to be followed on the target system.
In case of a Disaster Recovery scenario, it is highly advised to have these steps done in advance.
Install the Oracle Software on the target System
While it is not necessary, it is recommended to install the Oracle software under the same path and
the same Operating system user and group.
• Use the same Operating System user for the oracle software installation
• Install the Oracle Server Release on same location
• Apply the same Patch set level and patches as on the original system
• Prepare the oracle user environment (profile and needed environment variables)
