You can set up z/OS to be either an NFS client (data resides on the "other side" and is read via TCP/IP from z/OS) or an NFS server (data resides on z/OS and read by "the other side"). The plus of the NFS server is that the data is on z/OS. Usually better protected, backed up, disaster recovery, etc. Also, the NFS server can be set up to allow reading and writing of z/OS legacy datasets such as sequential and VSAM. The restriction on VSAM is that it is for KSDS only and only in sequential (by key) processing, not direct by key or RBA. With sequential, you can even allow creation and deletion. IIRC, creation of a new GDG by relative generation (+1) is not allowed but creation by absolute generation .GnnnnV00 is all. I am like 80% sure of this but don't have the time right now to double check it. The single biggest problem with the NFS server is that it cannot "serve" the same "exported filesystem" in both ASCII and binary modes. It is strictly one or the other. So how to use this with Winbloze? Get NFS client or server software for Windows and then map to it from other Windows boxes. Or get a Linux server and use Samba for disk sharing with Windows . Have the Linux box (of whatever flavor - xSeries, iSeries, pSeries, zSeries, ...) do the NFS stuff as above. CAUTION: I have not done any of this. No warranty expressed or implied. You mileage may vary. Well, I did use the z/OS NFS client to mount a z/Linux filesystem with good results. But not the other way around. -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.
