DCMT VARY LINE Parameters

broadcast-parms

Indicates to execute the DCMT command on all or a list of data sharing group members.

Note: For more information about broadcasting and broadcast-parms syntax, see the section How to Broadcast System Tasks.

LINe

Specifies the line being varied.

All physical terminals associated with the specified line are varied (unless the CONTROL UNIT parameter is specified).

line-id

A line ID assigned on the system generation LINE statement.

Control Unit

Directs that only physical terminals with the specified control unit number be varied.

This parameter applies only to remote 3270 lines using either BTAM binary synchronous nonswitched multipoint lines (line type R3270B or BSC3) or BTAM binary synchronous switched lines (line type BSC2).

control-unit-id

An integer in the range 0 through 31.

RLN

Directs that only physical terminals connected to the specified relative line number be varied.

This parameter applies only to physical terminals using binary synchronous line types (BSC2, BSC3, and R3270B).

relative-line-number

The number of the line.

ONline

Restarts the named line.

This action may be necessary if the line is defined as DISABLED at DC/UCF system generation time or has been varied OFFLINE or DISCONNECT, or if a line driver task has abended.

For connect type lines (UCF, VTAM, TCAM, BSC2, and start/stop lines defined as CONNECT at DC/UCF system generation time), new connection requests are accepted. However, automatic connections are not established for VTAM ACQUIRE and TTY AUTODIAL lines.

OFFline

Terminates activity on the line.

Current terminal I/O operations are halted, and new I/O requests are disallowed. For connect type lines, all terminals associated with the line are disconnected and future connection requests are disallowed.

QUIesce

For connect-type lines, disallows new connection requests for the line. However, current terminal sessions are permitted to continue until each respective terminal invokes the BYE task.

CONNect

For connect-type lines, restarts the named line. New connections are accepted, and automatic connections are established (for VTAM ACQUIRE and TTY AUTODIAL lines).

DISconnect

For connect-type lines, terminates activity on the line. However, new connection requests are accepted, and automatic connections are established.

WEIGHT weight-factor

For DDS lines, specifies the weight factor for the line.

Note: Changing the weight factor dynamically is supported but does notaffect processing, which is determined by the initial weight factor established by system generation.

MASter

For binary synchronous lines, gives the current DC/UCF system priority when communicating to the other point on the named line.

SLAve

For binary synchronous lines, directs the current DC/UCF system to defer to the other point on the named line when communicating.
