The System Administrator's Companion to AS/400 Availability and Recovery

An IBM Redbooks publication


This IBM Redbooks publication serves as a companion to other sources of availability and recovery topics, which most
significantly include the Backup and Recovery manual, SC41-5304. It offers a collection of tips
and techniques from many sources, including professional consultants specializing in availability, recovery,
systems management, and performance. Plus, it highlights new availability and recovery features for V4R2
and significant functions from earlier releases.

The information in this book assumes that you are familiar with AS/400 operating procedures, such as
using commands to save your system. It also assumes that you understand basic problem determination
techniques, such as where to find error messages and how to report problems.

This book was written for the AS/400 system administrator. System administrators are responsible
for ensuring that the AS/400 system maintains a level of availability to meet business demands. Their
responsibility includes:

* Ensuring the system is backed up in the event that recovery is needed
* Enforcing and monitoring the backup and recovery plan
* Planning for, implementing, and managing the appropriate hardware and software components
to ensure a level of availability consistent with business requirements
* Defining system-wide values that affect save-and-restore operations, data integrity, security,
and performance
* Enabling the techniques and tools to automate save-and-restore procedures
* Maintaining reliable documentation for changes made to the system

As IBM continues to enhance the availability of the AS/400 system and improve save-and-restore
functions, more tools and techniques are readily accessible to maintain your system's availability.
This book can help you understand the features of the AS/400 system, increase your system's
availability, and prevent or reduce the impact of an outage.
