FXotm Operations
An FXotm operation transfers the data from an open-system file on an FX
volume to a target dataset on an z/OS volume. The FXotm source file must be
located on an FX -C or -A volume on the subsystem. FCU does not
automatically create the FXotm target dataset. The target dataset must be
created and properly formatted prior to beginning the FXotm operation.
The FCU software performs the FXotm data transfer operations. FCU version
01-01-40 or later is required for VSE target datasets. FCU supports fixed-
length and variable-length record formats for FXotm operations. FCU provides
the following options for FXotm operations (see section FCU File Transfer
Options): code conversion, padding (01-01-41 and later), delimiter, empty
file, and VSE record. The record description word option cannot be used with
FXotm. FCU automatically extracts delimiters from FXotm source files, but
cannot add delimiters to FXotm source files. FCU can add padding only to
variable-length FXotm source files. FCU cannot extract padding from FXotm
source files. The types of FXotm operations are:
• FXotm with fixed-length record format
• FXotm with variable-length record format
The table below specifies the record format requirements for each type of
FXotm operation. An open-system source file with fixed-length data entities
can only be transferred to a fixed-length target dataset. An open-system
source file with variable-length data entities must have delimiters and can be
transferred to a variable-length or fixed-length target dataset. If the source
file contains padding from a previous FXmto transfer operation, the padding is
transferred to the target dataset along with the data. If the source file contains
delimiters, the delimiters are not transferred to the target dataset.
Note: Do not update the volume that is transferred directly by the FXotm.
