Software Reference Manual - NetEx

Introduction
The Bulk File Transfer (BFX) utility is a software package to be used with NetEx Software’s NETwork
EXecutive (NETEX) software. BFX and NETEX provide the software to rapidly move large amounts of sequential
file data between processors. The processors may use different operating systems or be of different
manufacturer, provided they have an IP network and the proper NETEX products installed (H211 BFX requires
H210IP or H210IPZ).
BFX uses batch processing facilities to perform file transfers. As a result, it has all the options of a batch program
to access data base systems or other media supported by the queued sequential access method (QSAM).
Also, as a batch utility, BFX can be run as a batch job, from a TSO terminal, or as an operator procedure.
BFX can be used to transfer files between different hosts which may require specialized record or data conversion.
BFX allows the use of NETEX code conversion. For other code conversion, BFX has a set of user
exits that allow user modules to process data both before and after transfer over the network. These modules
may take responsibility for accessing data. This makes it possible to copy and convert complex data between
different systems, or copy direct access files or data bases. The requirements for creating the user modules are
described in “User Modules” on page 63.
Supported Configurations
BFX uses the NETEX communications subsystem and IP networks for its data communications. It is designed
to use all the capabilities of these products to move files at multimegabit speeds over local (LAN) or WAN
IP-based networks.
Sample Network Configuration
BFX requires that cooperating batch application programs reside in both the source and destination CPUs, as
shown in Figure 1 on page 2.
