Introduction

For a high-availability implementation procedure to be effective, it must be based on a system that has been thoroughly cleaned up and brought under control.

Objectives

Our expertise can provide you with solutions in a variety of fields related to high availability.

Before implementing a mirroring tool, it can be advantageous to perform an audit on the machines involved in order to:

• Precisely define the perimeter and the objects to reproduce;
• Clean up the perimeter by deleting or moving all unnecessary components.

To guarantee data coherency at all times, we provide our Solution-supported assistance for commit control implementation (commit/rollback) in your programs.

Implementation

Implementation can be broken down into steps adapted to your configuration and goals. The first, essential step for any audit is a cleanup of component applications.

• This phase unearths all of the unnecessary elements in the work environments that can have a negative impact on copying. Archiving frees up disk space and brings needed clarity to libraries.
• Loading and structuring the ARCAD database (the Repository) as a three-level tree provides a macroscopic view of your applications and allows clear definition of the relevant perimeter.
• Using ARCAD-Observer tools brings visibility to programs and the links between them. Necessary modifications for commit/rollback management are more easily added.
