About Cross-OS File Exchange Operations 2-29
Hitachi USP V Cross-OS File Exchange User’s Guide
With padding and delimiters. The figure below shows an FXotm operation
with padding for a variable-length source file with delimiters. FCU version 01-
01-41 or later is required for FXotm with padding added to variable-length
source files. FCU adds padding, extracts and transfers the data entities with
padding to the target dataset, and automatically adds the four-byte RL field.
The delimiters are not transferred. The target dataset must have fixed-length
record format with record length defined as needed.
Open-System Source File Target Dataset
Record length + 1 or 2 bytes Record length
Data entity 1 D Record 1: Data entity 1 + padding
Data entity 2 D → Record 2: Data entity 2
Data entity 3 D Record 3: Data entity 3 + padding

Delimiters
If the length of any data entity in a UNIX source file is greater than the
specified record length plus one byte (CR or LF delimiter), FCU aborts the
operation and reports an error. If the length of any data entity in a Windows
2000/2003/Windows NT source file is greater than the specified record length
plus two bytes (CR+LF delimiter), FCU aborts the operation and reports an
error.
FXoto Operations
FXoto operations transfer data from source files on one open-system platform
to target files on another open-system platform. Each FXoto file transfer
consists of two separate FX operations: first an FXotm operation transfers the
data in the source file to an intermediate dataset, and then an FXmto
operation transfers the data from the intermediate dataset to the target file.
For any users with the all-open TagmaStore USP or NSC subsystem (no
attached z/OS host), the intermediate datasets are allocated on OPEN-x FMT
volumes. The FMT utility enables you to format OPEN-x LUs (standard or
custom size) as FXoto volumes. The ALC utility enables you to allocate
intermediate datasets on the OPEN-x FMT volumes. For users with the
multiplatform TagmaStore USP or NSC subsystem, the intermediate datasets
can be allocated on OPEN-x FMT volumes or on FX -A volumes, as desired.
When you perform FXoto operations which access OPEN-x FMT volumes, the
FXoto volume definition file must be available for use by FCU.
