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.
This guide contains three chapters and an appendix:
Chapter 1, “IRIS FailSafe INFORMIX Overview,” describes the IRIS FailSafe components that are included in the IRIS FailSafe INFORMIX option. It also provides an overview on the steps required to add INFORMIX databases as highly available services to an IRIS FailSafe cluster.
Chapter 2, “Configuring IRIS FailSafe for INFORMIX,” explains the procedures for adding INFORMIX databases as highly available services.
Chapter 3, “Configuration File Blocks for INFORMIX,” contains reference information for the INFORMIX blocks in IRIS FailSafe configuration files.
Appendix A, “Messages About Configuration File Errors,” explains the error messages and warnings from the ha_cfgverify command that are related to INFORMIX.
For INFORMIX installation information, see the Informix Installation Guide Version 7.1 for UNIX Products.
