Well, I ran Informix on my Red Hat Linux 5.0 box for a while. It was a bit
pathetic in that it did not have an API for C++: only for C. So I ended up
writing a large bunch of C functions to interface to the Informix server.
It worked, but sloppy. Then I upgraded to Red Hat Linux 6.0 and Informix
never worked again. I e-mailed Informix about it and they said they did
not know if it would work with 6.0 or not. I said I would be glad to test
it for them, but that the CD-ROM I had would not read and could they send
me another one. They never answered any e-mails after that.
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.
