Tachyon Un-Xmit - Generating a TRANSMIT File

The first step in copying a data set using Tachyon Un-Xmit is to create a TRANSMIT data set. This is done using the IBM TSO/E “TRANSMIT” command. The TRANSMIT command copies a sequential file, an entire partitioned data set or selected members of a partitioned data set to a transportable sequential data set that is in a format that allows the original data to be recreated. TRANSMIT cannot copy VSAM data sets directly. To copy a VSAM data set, you must first copy it to a sequential data set using IDCAMS REPRO and then TRANSMIT the sequential copy.

The second step in copying a data set is to get the transportable sequential data set to your workstation. TRANSMIT was designed to send the copy of the orginal data set to its destination as long as the destination is another mainframe. In this mode, the transportable copy of the original data set is not retained. To send a copy of a data set to a personal computer using TRANSMIT, you must instruct TRANSMIT to retain the transportable copy of the data set and then transfer that copy to your computer using FTP, NFS, IND$FILE or any other mainframe-to-PC file transfer method. The TRANSMIT data set must be copied in binary mode.

The information that follows describes the TRANSMIT command options needed to generate a TRANSMIT data set for use with Tachyon Un-Xmit. The syntax for the TRANSMIT command is fully described in the TSO/E Command Reference and further information is available in the TSO/E User’s Guide - Sending and Recieving Data Sets.

TRANSMIT Command Syntax

The required TRANSMIT command syntax is:
XMIT addressee DATASET(in-dsname) OUTDATASET(out-dsname) [MEMBERS(member-list)]
where:

XMIT

The command name may be specified as XMIT or TRANSMIT.

addressee

The TRANSMIT command requires the addressee parameter even though it is not used when the OUTDATASET parameter is used to retain the transportable copy. You can use any valid value such as: NODE.ME.

DATASET(in-dsname)

The DATASET parameter names the sequential or partitioned data set to be copied. Usual TSO/E syntax is required for the data set name. The data set name must be enclosed in single quotes unless PROFILE NOPREFIX is set or the high level qualifier of the data set name is the same as the PROFILE PREFIX value and the high level qualifier is omitted from the name.

OUTDATASET(out-dsname)

The OUTDATASET parameter names the data set into which the transportable copy of the original data set is to be written. This is the data set that should be sent to your workstation to be read by Tachyon Un-Xmit. The data set must already exist. The DCB attributes will be RECFM=FB LRECL=80 BLKSIZE=3120. The normal TSO/E rules for specifying data set names apply to this parameter.

MEMBERS(member-list)

The MEMBERS parameter may be used to select the partitioned data set members to be transmitted. If not specified, the entire partitioned data set is copied. If more than one member name is specified, they must be separated by commas.

Example:

XMIT NODE.ME DATASET('PROD.LOADLIB') OUTDATASET(XMIT.COPY) MEMBERS(PROG1,PROG3)
