Figure 2-2 FXoto System Configuration
The FCU program provides the commands and graphical user interface (GUI)
for FX file transfer operations as well as several important options for data
exchange, including EBCDIC-ASCII code conversion and data record padding
and delimiters. The FAL is a library of C functions (Visual C++
® for Windows
NT ® ), which provides an application-programming interface for data exchange.
The FAL functions can be called by user application programs to read and write
data in z/OS datasets on the TagmaStore USP and NSC. There are two types
of FAL, the 32bitFAL and the 64bitFAL. The latter is provided by the
TagmaStore USP and NSC. The FMT and ALC utilities enable the all-open
TagmaStore USP and NSC user to format OPEN-x logical units (LUs) and
create intermediate datasets for FXoto operations, without having to be
attached to any z/OS hosts. OPEN-x is defined as a standard LU type. The
TagmaStore USP and NSC subsystem currently supports OPEN-3, OPEN-8,
OPEN-9, OPEN-E, OPEN-L and OPEN-V devices. Please contact your Hitachi
Data Systems account team for the latest information on supported LU types.
