MCS (Message Control System)

The MCS (Message Control System) command displays the summary and status information, including the number of in-use sessions, about each of the message control systems (MCSs) that are supported by the system at the time you issue the command. You define an MCS to the system by declaring it in the current DATACOMINFO file, as specified by the ID (Initialize Data Comm) command.

Syntax

Explanation

The MCS command provides the following summary and status information.

Display

Meaning

MIX

Mix number of the MCS if active.

STATUS

The MCS can be in one of four states:

  • ACTIVE: The MCS is running.

  • INACTIVE: The MCS is not running. The previous execution of the MCS either terminated normally or an attempt to execute the MCS has not been made.

  • DSED: The MCS has been terminated abnormally.

  • REQUIRED: An unsuccessful attempt was made to initiate the MCS. The MCS could not be initiated because it had previously terminated abnormally or the code file of the MCS was not found. This failed attempt at initiating the MCS causes an MCS REQUIRED message to be displayed at the ODT.

TASKS

The number of currently active tasks that were initiated from the MCS.

STATIONS

The number of logical stations owned by the MCS.

SESSIONS

The number of sessions owned by the MCS.

NUM

The number of the MCS.

MCS SUMMARY

The name of the MCS. Any family specified for an MCS name is the default family for that MCS in the DATACOMINFO file. It is not necessarily the family upon which the currently active MCS code file actually resides.
