z/VM Version 4, Release 2.0 - NFS Client Improvements

One improvement this release is the addition of the LOCALPORT option. This allows the user to identify the local reserved (well-known) port number CMS should use if reserved ports are required by the remote NFS server. For example, by default, some NFS server implementations on LINUX require that the client use reserved ports.

z/VM Version 3, Release 1.0 - NFS Client Added!

Would you like to use XEDIT instead of VI to edit LINUX files? Would you like to use CMS Pipelines to process OS/390 data sets? Would it be useful to have multiple writers sharing a CMS minidisk? Do you have a VM tool that you'd love to use on other files that reside on another platform?

All of this is possible with z/VM's new NFS client support.

The OPENVM MOUNT command allows you to make a remote file system part of the Byte File System (BFS) directory structure in your CMS virtual machine. (See the z/VM OpenExtensions™ Command Reference for a description of the OPENVM MOUNT command.)

What can you do with it once it is mounted?

• Use XEDIT with the (NAMETYPE BFS option to edit remote files using the tool we know and love.

• Use OPENVM GETBFS and OPENVM PUTBFS CMS commands to copy files to or from the remote file system.

• Add a front-end to an existing CMS EXEC so that a CMS Pipelines BFS stage reads the input file from a remote file system.

• NFS Mount a CMS minidisk so you have read/write access from multiple CMS users.
  (Warning! This provides an update-in-place type sharing capability.)

• Use files in remote file systems in OpenExtensions Shell commands.

  The Shell and Utilities was a priced, optional feature of VM/ESA was integrated into the CMS component of z/VM Version 3 Release 1, renamed to OpenExtensions Shell and Utilities and was made available at no extra charge.
