can run HDR and ER simultaneously on the same server IDS 9.20??
A DBA running about 80 IDS 9.20 servers on SCO UnixWare (one ER root server plus leaf servers) asked whether HDR could be used alongside Enterprise Replication on the same machine to mirror the root server's databases to a disaster-recovery site ~200 km away, and whether ER and HDR threads would conflict at that distance. The only reply pointed to IBM's HACMP/XD (extended distance) clustering and a related white paper, noting it was AIX-only and costly. The ER/HDR coexistence and distance questions were never directly answered; no resolution is recorded.

Hello all, I administrate about 80 servers running IDS 9.20 and SCO Unixware 7.1. At this moment we use ER: one server is root server and the other are leaf servers. We build a disaster recovery center and we want to replicate whole databases on the root server on this location. how can we do this? Can using HDR for this? Is their likely to be conflict between the ER and HDR threads on the same server(machine)? The distance between main location and disaster recovery location is about 200 km.It's possible HDR at this distance? Thank you very much! Regards, Cristian
Check out the IBM product : HACMP/XD Look for the white paper "Automated Recovery Management With IBM HACMP/XD and PPRC" on the www.ibm.com website. The "XD" is significant, meaning eXtended Distance. It is not yet available for Linux last I heard but is available on an AIX platform. If you go AIX on Power5 they're running around $25K USD for a p550 machine. ( HACMP/XD costs additional.
