DDS Parameters

LINE Statement Parameters

TYPe is DDS

Specifies DDS as the line type.

SOUrce is application-id

Specifies the VTAM LUNAME of the DDS application to be created by the line driver.

PTERM Statement Parameters

TYPE

BULK

Specifies the data transfer between DC/UCF systems is BULK. You must define at least two PTERMS with a TYPE of BULK.

VTAM

Specifies the PTE that will be used to transmit packets through a VTAM communications link. Specify VTAM if the connection being established is between two nodes residing on the same or different machines connected by VTAM. You must define at least one PTERM with a TYPE of VTAM.

If you specify VTAM, you must specify the TARGET parameter and optionally the BLOCKSIZE and WEIGHT parameters, which are described below. For additional information about DDS VTAM considerations, see VTAM Considerations and the CA IDMS DDS Design and Operations Guide.

BLOcksize

Specifies the size of the buffer to use to pass run unit request and response packets between nodes. If two connected nodes specify different block sizes, DDS uses the smaller size.

8192

Specifies the default block size.

block-size

Specify an integer in the range 1 through 32,767.

TARget application application-id

Specifies the VTAM LUNAME of the destination application program. Application-id is a unique one- through eight-character name that corresponds to an ACB name or label specified in an APPL statement. This name must correspond to the application-id specified on the DDS LINE statement SOURCE parameter for the target node.

WEIght factor

Specifies the priority to assign to the port defined by this physical terminal and its associated line.

0

Specifies the default weight-factor.

weight-factor

Specify an integer in the range 0 through 999,999,999.
