Sending a File
39
TTYPE(entry-name)
specifies the entry name of the type defaults file on the remote node that contains the default file
attributes used to allocate the destination file.
attributes used to allocate the destination file.
TUNIT(file-address)
specifies the unit address, device type, or user-assigned group name where the file resides or will
reside. For SAM-to-SAM copies where the destination file is new and the UNIT parameter is not
coded, the device type from the source file is used. For VSE nodes, you must specify either this
parameter or TVOL.

coded, the device type from the source file is used. For VSE nodes, you must specify either this
parameter or TVOL.
Specify a unit-count to allow additional units to be allocated if required, or specify P to allocate the
same number of units as volumes and then parallel mount the volumes.
same number of units as volumes and then parallel mount the volumes.
TVOL(private, volcount, ser)
specifies the volume serial number or numbers containing the file and optional processing associated
with the file. If TVOL is not specified, the file must be cataloged. For VSE nodes, you must specify
either this parameter or TUNIT.
with the file. If TVOL is not specified, the file must be cataloged. For VSE nodes, you must specify
either this parameter or TUNIT.
private specifies allocation of an output file only if the volume is specifically requested and is used
for direct access storage devices only. Valid values are *YES and *NO.
for direct access storage devices only. Valid values are *YES and *NO.
volcount specifies the maximum number of volumes required by an output file.
ser identifies by serial number the volumes on which the output file resides or will reside.
TVOLREF(data-set-volume)
allows you to place a data set on the same volume as the referenced data set. It must be cataloged on
the system where it is referenced.
the system where it is referenced.
TVSAMCAT = (dsn, vmid, pwd, accmode, cuu)
specifies the catalog for the VSAM file to be copied. This parameter is required only if using a catalog
other than the master catalog. This parameter is for a VSE or VM remote node.
other than the master catalog. This parameter is for a VSE or VM remote node.
dsn specifies the filename of the VSAM catalog containing the file to be copied. The maximum length
is 44 characters.

vmid specifies the owner ID for the VSAM minidisk where the file is located. The maximum length is
eight characters.

pwd specifies the appropriate password for the VSAM minidisk where the file is located. The
maximum length is eight characters.

accmode specifies the link access mode. Valid access modes are NULL, W (primary read/write
access), M (primary multiple access), and MW (primary multiple access; alternate read/write only
access).

cuu specifies the virtual address of the disk where the VSAM file is located. Any three-digit number
is valid.

Using Block Mode Transfer
Sterling Connect:Direct for i5/OS supports block mode transfer for send operations. In this mode, Sterling
Connect:Direct uses the file block as the data unit. Using the block mode transfer improves performance
because the sending and receiving nodes handle fewer data units. This type of transfer reduces instruction path
length and decreases execution time. Larger units move between Sterling Connect:Direct and the file access
routines, requiring fewer calls to the access routines and further improving performance.
