When a remote file system is mounted on your local machine, it appears to you in most cases as if it were local. That means you can run applications from that file system, but of course they are loaded into your local machine's memory and run there, not on the remote machine. Apart from the longer loading time, you should not see any performance degradation, unless the program does a lot of disk I/O on the remote disk. : 3. How well does Informix work with NFS? Do we need to get I-Net or some : such, or can we just mount the remote file system and pretend it is local? It doesn't, generally. There are some things that you can do with an SE database that resides on a remote disk, like SELECT, but you cannot, for instance, do a CREATE DATABASE. This has something to do with locking mecha- nisms. If you want to work with Informix databases on a remote machine, you need I-NET on both machines (or I-STAR on the server if it runs Online).
