TCPware FAQ: NFS

 

Added proxies not being used

If the proxy entries were not set up with the TCPWARE_NFS_DYNAMIC_PROXY logical defined the client or server will not reload the proxy database when there are changes. You can use the NETCU RELOAD PROXY command to force the changes into effect. The reload blocks NFS activity while the client and/or server reloads the database. The client can take a significant amount of time.


Why is the /CONVERT=STREAM_CRLF option not converting files from the client?

When an export is mounted with the /CONVERT=STREAM_CRLF or /CONVERT=STREAM_LF and a file is copied to the export, the file that is produced on the NFS server does not appear to be converted. There is no CR LF (X0A X0D) or LF (X0A) in the file.

The NFS client does not perform conversions when 'block mode transfers' are performed. COPY and also EDT use block mode transfers when copying or creating files. Instead of COPY the CONVERT command can be used. Instead of EDT, TPU can be used. Most applications do RMS sequential access when they create files on the export and these will be converted.

You can only convert files opened using RMS sequential access to STREAM_CRLF or STREAM_LF format when written by the client.


When using the NFS server to export directories to my PC clients, files created on the OpenVMS server show up on the PC as one record.

TCPware’s NFS server allows you to configure how files are converted when they are read from the client and also what format to use when creating new files. These settings are controlled with the /CONVERT and /RFM options when adding the exports with the NETCU ADD EXPORT command. The /CONVERT tells the server how to convert files on reads. The default value is STREAM_LF that is useful when the export is being accessed by UNIX systems. Exports that are going to be accessed by PC should use the /CONVERT=STREAM_CRLF. STREAM_CRLF will add a carriage return and line feed to the end of each record.

You can use the /RFM option to control the record format of newly created files on an export. If the export is being accessed by a PC, the /RFM=STREAM will create files without the extra carriage return in them when being edited.


%NFS-W-CANTCVT error

Certain types of files (object files, database files, etc.) can't be converted due to their make-up or record sizes.

If you have many files of this type it might be useful to export the directory using the /NOCONVERT option.
