RE: HDR on Informix

Should work just fine -- we have done it several times, even with some 7Gb instances. The server pairs are hundreds of miles apart, and we just ftp the archive files (we archive to disk) over to the new secondary. Our outages have almost always been planned switchovers, so that work can be done on the primary server. Haven't had to deal with any fires or earthquakes, yet, thank God. :-) HTH, Paul Mosser -----Original Message----- From: Pankaj Patel [mailto:pankaj@punks.demon.co.uk] Sent: Wednesday, June 14, 2000 3:40 AM To: informix-list@iiug.org Subject: HDR on Informix HI All , Current version of Informix 7.30.UC3 UNIX :- Solaris 5.6 Wondering if any body knows if the following has problems. We are setting up HDR on two servers.The primary is going to be where all the IT staff are and the secondary is 5hours down the road with know techies there. If ever the primary server goes down(due fire, earthquake etc ) and we change the secondary server into standard mode so that all the users can continue processing. The back-ups & logs will then be done at the second site which has a tape drive. Question:- 1. Are there any issues with bringing the Secondary server on-line as a Primary and then take a copy of this to make the primary server now the secondary server ? I have tried this out and it worked. But the Informix manuals only only show how to bring the secondary back up as a secondary and recover the primary. The reason I am asking if this is possible is that the network connection between the two servers is a 512K line. To recover a 6G DB & logs over the line would take to long. It would be quicker to send a archive & log tapes once taken via a courier. This allows us time then to recover the secondary server at a scheduled maintenance slot. Cheers & thanks in advance.
