Which is why I upgraded to IBM DB2 UDB V6.1 which worked just fine. Since I am cheap, I kept V6.1 through upgrades to RHL 6.2 and 6.3. Now DB2 V6.1 did not really like RHL 7.3. It worked because there were some "compatability libraries" that could be used, but it meant I had to change all the makefiles to use those libraries, including getting it to use the compatibility version of ldd.so.
Anyhow, when I built this machine I put Red Hat Enterprise Linux 3 ES on it and installed IBM DB2 UDB V8.1 (upgraded to 8.1.5) and after a fight to get it installed (graphic installer does not work), it runs just fine on a dual hyperthreaded Intel XEON machine with 4GB (expandable to 16 GB if I found I needed it).
Unless Informix has been greatly improved since the time RHL 6 came out, I do not see why anyone would wish to use it unless it is a lot cheaper than DB2.
My needs are quite modest, since I am running it single-user for a single small (by dbms standards) database. But back when I started, postgreSQL and Oracle were the other alternatives, and postgreSQL did not run right (one version would not allow primary keys to be specified, and another was unable to have views), and Oracle's license agreement was so complicated that I refused to sign it.
If a small user such as I can use it, I see no reason why a larger user could not.
