This chapter describes how to plan, configure, start, and monitor High-Availability Data Replication (HDR) for Dynamic Server, and how to restore data after a media failure. If you plan to use HDR, read this entire chapter first. If you plan to use IBM Informix Enterprise Replication, see the IBM Informix Dynamic Server Enterprise Replication Guide.
High-Availability Data Replication (Enterprise/Workgroup Editions), explains what HDR is, how it works, and how to design client applications for an HDR environment.
HDR is available with the standard version of Dynamic Server. HDR does not work with the IBM Informix Dynamic Server Express Edition.
