FL310 for VM/ESA V2R3 NFS Release Changes
- Function Level 310 for VM/ESA Version 2, Release 3
Following are changes introduced in this release that are of interest to end users.
- Byte File System (BFS) and Shared File System (SFS)
directories can be mounted!
- New LINES= and TRANS= parameters take the place of the
RECORD= parameter. LINES= tells the VM NFS server
how you want to make the transition between CMS
records and a byte stream. TRANS= tells the VM NFS server
whether or not you want to translate between ASCII and EBCDIC.
LINES=EXT and TRANS=EXT tell the VM NFS server that you want different translations done based on file name extensions. For example, with a single MOUNT:
- files with an extension of .bin
can be read or written as binary files,
meaning no ASCII/EBCDIC translation takes place, and no line-ends
are inserted or removed, and
- files with an extension of .txt can be read or written as text files, meaning ASCII/EBCDIC translation takes place and line-end values are inserted or removed.
LINES=NONE tells the VM NFS server to eliminate CMS variable record format information from the data presented to the NFS client.
- files with an extension of .bin can be read or written as binary files, meaning no ASCII/EBCDIC translation takes place, and no line-ends are inserted or removed, and
- You can specify the one- or two-byte value to indicate the
end of a line.
Many NFS clients programs
use 0D0A for the line-end value.
- With APAR PQ19040, you can choose from many different translation
tables for ASCII/EBCDIC translation.
- With APAR PQ16301, your Windows® client can pass user ID and
password information to the VM NFS server using PCNFSD, eliminating the
need to include this information on the MOUNT string.
- The SMSG ERROR command allows a CMS user to retrieve more detailed error information for an error using a BFS or SFS file.
Following are changes introduced in this release that are of interest to the administrator of the VM NFS server machine.
- The administrator can allow or
disallow ANONYMOUS requests to mount
BFS and SFS directories.
DTCPARMS file provides a more consistent method of administering
different types of TCP/IP server machines.
provides a consistent
way to specify start-up exits and parameters,
whether ANONYMOUS requests are allowed, and whether an External
Security Manager (ESM) is in use.
- More detailed
tracing is available with the use of the
MASK start-up or SMSG command. Subsetting of trace information is
- The VMNFS CONFIG file allows you to configure your VM NFS server machine. For FL310, you can define the values used for file extension translation, and you can define whether or not PCNFSD is supported.
- Byte File System (BFS) and Shared File System (SFS) directories can be mounted!
