In my expreience of HDR(which is the replication you are speaking of) requires os and hardware to be exactly the same. Therefore your current hardware setup will not work. Another type of replication from Informix is CDR. This does not require identical hardeware but is a bit more difficult to maintain. I do not know, though, if it is supported on the SCO platform... -Jacque Kai Shen wrote: > Hi, > we are thinking of replicating our DB server to a second one for > migrating reasons. > The manuals say, the OS and the hardware of both server must be > identical. > To which detail is this true?
