Database mirroring without ER or RDH ??

Hi, does anybody know of a solution to mirror database contents via Internet = on different platforms and OS's ? I know about the HDR (High Availability Da= ta Replication) feature of OnLine, but our problem is that this feature does= only work on identical machines and OS's. So what I'm looking for is a way to update several mirror database server= s in a non redundant manner (only changed entries are updated). Our Informix OnL= ine Version 7 does not have a C-interface that allows for data access and manipulation by an external application, so it's impossible to solve the = problem by writing an external application that handles the mirroring. Any hints appreciated cheers, Stefan = -- Stefan Schuster | phone:++34-4-420 95 19 = European Software Institute, ESI | fax: ++34-4-420 94 20 Parque Tecnol=F3gico de Zamudio # 204 | email:Stefan.Schuster@esi.es 48170 Bilbao, Vizcaya | http://www.esi.es Spain
