Parameters
  • broadcast-parms
    Indicates to execute the DCMT command on all or a list of data sharing group members.
    For more information about broadcasting and
    broadcast-parms
    syntax, see the section How to Broadcast System Tasks.
  • LU
    Specifies a logical unit to be displayed.
    • logical-unit-name
      The name of a logical unit.
      Information is displayed for all modeents in the logical unit, unless you specify MODEENT as described below.
  • MODeent
    Specifies a VTAM modeent to be displayed for the specified logical unit.
    • vtam-modeent-name
      The name of a VTAM modeent.
  • LUs
    Displays summary information for each logical unit.
Usage
How to View Displayed Information
When you specify a modeent name, DC/UCF displays information for one modeent at a time. To page to another modeent in the logical unit, press Enter or enter the page number for the modeent to display.
Display for Each Modent
The following information is displayed for each modeent associated with the unit, or for the specified modeent or model:
Field
Value
Pline-ID
Identifier of the physical line to which the logical unit is attached
Log.Unit
The name of the logical unit
Modeent
Name of a modeent associated with the logical unit.
Status
Status of the modeent:
CLOSED -- the physical line is closed
DISCON -- no sessions are active, but sessions could be activated
DRAINED -- the sessions will be put out of service after there are no more pending requests
INSRV -- at least one session is active
OUTSRV -- the physical line is open, but no sessions can be activated
Maxses
Maximum number of sessions that currently can be active for the logical unit.
Minwin
Minimum number of sessions for the logical unit that are defined as contention winners.
#WAIT
Number of waits for an available session.
#BREJ
Number of bracket rejects signaling contention with the logical unit.
#TRANS
Number of transactions on the mode.
Display for Each Logical Unit
The following information is displayed for each logical unit:
  • Number of physical terminals in the logical unit at system generation time
  • Maximum number of sessions
  • Minimum number of contention winners
  • Minimum number of contention losers
  • Current number of contention winners
  • Current number of contention losers
  • Number of transactions
  • Total waits for sessions
  • Current waiting session
  • Number of bracket rejects
