Hi folks, I have some problems running C-ISAM (on a Sun 3) on a file system mounted remote from a server via NFS. The C-ISAM routines always responds with an error code that, after som R of TFM, tells me that Informix Corp. doesn't like NFS. I haven't tried this with Informix-SQL or ESQL/C, but I assume the same problem exists there. Running C-ISAM and/or Informix on a local disk works, tough. Any suggestions? Thanks in advance, Robert

The following response is not meant as a product plug, but Mr. Claeson brought up a good point regarding NFS use, and I thought there might be enough interest to warrant posting.

We're good buddies now! :-] However, the current public releases of our products do not handle the niceties of NFS completely, so its use is disabled. Typically, you will get C-ISAM error -125 if you try to use remote data, I believe. Now for the good news: with the upcoming product releases (C-ISAM release 3.10.03, Informix-SQL, ESQL/C, and ESQL/COBOL release 2.10.03, Informix-4GL release 1.10.03, and I4GL Rapid Development System release 1.10.03), there will be standalone and network versions. The network products come in two flavors: NetDBS (server) and NetStation (clients). The network versions will utilize TCP/IP network protocols *including* NFS. The Sun 3 ports should be among the first done; call your distributor for more info and availability dates (my *unofficial* guess is in about a month). We have been using the network products in-house for quite a while; I had almost forgotten they weren't "real" products yet... > I haven't tried this with Informix-SQL or ESQL/C, but I assume > the same problem exists there.

The .03 release of the backend allows access of remote data as long as the server has the NetDBS product and is accessed via TCP/IP (or NFS, of course) and the local machine has the NetSTation product. You would just add the remote pathname (e.g. //machine/pathname) to your DBPATH environment variable for your local session. I hope this info proves helpful. -- Alan S.
