Problems with Informix in an NFS environment We have a NFS network with one server and several diskless clients. Our problem is that we cannot run Informix from our clients. To get our application running we need to remote login to the server and start it from there. We know that the Informix process is running as root, therefore we modified NFS so that root on each client has also root access to the server. But it is still not working. I would appreciate any help to get rid of this annoyance. Thanks for the help in advance.

That's because Informix doesn't believe in NFS record locking. The C-ISAM library actually checks if the file system you're running on is an NFS file system and, if this is the case, complains and refuses to do any work. Furthermore, Informix can only deal with one file system type at a time (I believe it's a compile time option). So, on our system which is using multiple file system types, we can only use Informix on one of them, namely the old System V 1K file system. We have all our file systems except for the root file system in BSD 8K format... And now a question for you guys using RFS: Does Informix run over it? -- Robert Claeson E-mail: rclaeson@erbe.se ERBE DATA AB

I suspect Informix doesn't believe in the correctness of NFS file caching, either. I suggest you junk NFS and run Freedomnet instead. Several customers have used Informix over Freedomnet for years with zip problems. AT&Ts RFS would probably do okay too, but I suspect RFS is not available on your favorite machines. Also, Freedomnet allows "true remote execution", which means that if any of your machines has Informix they all do. Very handy if your Informix is on a Sun but you have a bunch of Dec machines too. (This is useful for more than just Informix. For example, if *any* of your machines has a Korn Shell, you can make it your login shell. That's what I do here, so kind of HP-UX to give me a ksh server!) Sorry this is a commercial, but this Non-Faithful-Semantics stuff really ticks me off sometimes. For more info on Freedomnet contact Tom Warren, wtw@rti.rti.org, (919) 541-6110. Tom Truscott P.S. You don't have to junk NFS. Run both and take your choice :-) Hmm, I guess I need a disclaimer: These are my opinions exclusively.
