CEMT SET IRC
CEMT SET IRC
Function: Open or close the interregion communication
(IRC) facility.
Description: New MRO connections can be installed
without first closing IRC. However, if you want to modify
existing MRO connections, IRC must be closed using the
SET IRC CLOSED command. For example:
CEMT SET IRC CLOSED
CEDA INSTALL GROUP(groupname)
CEMT SET IRC OPEN
Syntax: Press the Clear key to clear the screen. There are
two ways of commencing this transaction:
Type CEMT SET IRC (the minimum abbreviation is CEMT S
IR). You get a display that lists the current status, similar
to that obtained by CEMT INQUIRE IRC. You can then
tab to the highlighted field and overtype it with the
required value.
Type CEMT SET IRC (CEMT S IR) followed by the attribute
setting that you wish to change. For example, cemt s ir
o will cause interregion communication to be initialized.
Typing ? at the beginning of either the first or second line
gives a syntax prompt. Resetting the values takes effect
immediately.

Closed
Interregion communication for this CICS system is to be
terminated after all tasks using IRC sessions have
terminated normally.
Immclose
All tasks using IRC sessions are to be abended when
they next try to use the session. Interregion
communication is terminated when all tasks that were
using IRC have been abended or have terminated
normally.
Open
Interregion communication for this CICS system is to be
initialized. This allows connections to be established
between this system and other systems, including DL/I
batch regions and non-CICS client programs using the
external CICS interface (EXCI). You can control the
availability of individual connections with the
INSERVICE|OUTSERVICE settings on the connection
names.
The DFHIR3780 message and CICS interregion
communication program (IRP) return and reason codes
are displayed if IRC fails to open. For a description of
DFHIR3780, see the
CICS Messages and Codes
manual.
