About This Guide

This guide provides information about configuring IRIS FailSafe systems with the IRIS FailSafe INFORMIX® database option. This option enables INFORMIX database resources to be failed over from one node to another if a component fails. This guide is intended as a supplement to the information about configuring IRIS FailSafe included in the IRIS FailSafe Administrator's Guide .

This guide was prepared in conjunction with the initial release of the IRIS FailSafe INFORMIX option. It describes IRIS FailSafe INFORMIX software for INFORMIX 7.12UC1.


This guide is written for system administrators who are responsible for configuring and administering an IRIS FailSafe system with the optional IRIS FailSafe INFORMIX software. These system administrators must be familiar with INFORMIX configuration.
