IDS 7.22 and 7.31 co-exist?
Hi all, I'm sorry if this is a 'stupid' question, I'm an AIX admin not Informix DBA, and I've been tasked with installing Informix 7.31 on an RS6000 (running AIX 4.3.2) which already has IDS 7.22 installed. I've done upgrades often enough, but the datacenter here want 7.31 and 7.22 running together, simultaneously. They don't want to try it the install, so it's come to me. Is it possible, and if so, are there any major hidden problems? I've looked through the sparse manuals we've got, the FAQ, deja.com et al, but could find no pointers. MTIA, FM.

Install in separate sub-directories, name then instances with different names (DBSERVERNAME * DBSERVERALIASES) and different server numbers (SERVERNUM). Use a separate set of port numbers in /etc/services for each instance and separate disk space. All will be well. You may want to get my aspace scripts to manage the disks in the two instances so they do not stomp on each other. Informix's utilities cannot tell if a disk you are asking the engine to use is already in use by another instance. Aspace can. It is in the package utils_ak in the IIUG Software Repository at www.iiug.org. Art S. Kagel
