Steps for sending data from a named pipe in the z/OS FTP client UNIX file system

Before you begin

You must start an application that can write from the named pipe, and it must open the named pipe, before FTP can transfer data into the named pipe.
You must create the named pipe. See MKFIFO command information in z/OS UNIX System Services Command Reference for more details.

Procedure

Do one of the following to set the UNIXFILETYPE FIFO value at the client host:
- Code a UNIXFILETYPE statement in the client FTP.DATA file before you start the FTP daemon. See the UNIXFILETYPE (FTP client and server) statement information in z/OS Communications Server: IP Configuration Reference for more details about the UNIXFILETYPE statement.
- Issue a LOCSIte subcommand with the unixfiletype parameter after you start the FTP client. See LOCSIte subcommand—Specify site information to the local host for more information about the LOCSIte subcommand.
Do one of the following to set the FILETYPE=SEQ value at the client host:
- Code the FILETYPE statement in the client FTP.DATA file before you start the FTP client. See the FILETYPE (FTP client and server) statement information in z/OS Communications Server: IP Configuration Reference for more details about the FILETYPE statement.
- Issue the LOCSIte subcommand with the FILEtype parameter after you start the client. See LOCSIte subcommand—Specify site information to the local host for more information about the LOCSIte subcommand.
  Tip: SEQ is the default value for the FILETYPE configuration option. You can use the locstat filetype subcommand from the z/OS® FTP client to determine whether you need to reset the FILETYPE value.
Optional: Do one of the following to set the FIFOOPENTIME and FIFOIOTIME values at the client:
- Code the FIFOOPENTIME and FIFOIOTIME statements in the client FTP.DATA file before starting the FTP daemon. See z/OS Communications Server: IP Configuration Reference for more information about the FIFOOPENTIME and FIFOIOTIME statements.
- Issue the LOCSIte subcommand with the FIFOOPENTIME and FIFOIOTIME parameters after you start the client. See LOCSIte subcommand—Specify site information to the local host for more information about the LOCSIte subcommand.
  The FTP client uses default values for the FIFOOPENTIME and FIFOIOTIME configuration options if you do not configure these values explicitly.
On the FTP client host, start the process that writes to the named pipe.
Issue the Put subcommand to transfer a file from the client to the server. Specify the named pipe as the local file as follows:
put local_named_pipe remote_file

Results

You know you have completed these steps correctly when both of the following events occur:

The client receives reply 226 or 250 from the server, which indicates that the server received the file.
The client issues message EZA2536I or EZA1617I, which indicate the total number of bytes that it sent.
