indicates that this panel relates to an IRC inquiry.
Openstatus( value)
displays whether the interregion communication (IRC)
facility is open or closed. The values are:
Closed
Interregion communication for this CICS system is
terminated after tasks using the session have
terminated normally.
Open
Interregion communication for this CICS system is
initialized. This allows connections to be
established between this system and other
systems. You can control the availability of
individual connections with the INSERVICE or
OUTSERVICE settings on the connection names,
using CEMT INQUIRE CONNECTION or CEMT
SET CONNECTION.
The DFHIR3780 message is issued to the console
log if the region made an unsuccessful attempt to
start IRC.
Notes:
1. You can reset this value by overtyping it with a
different value, or with:
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.
2. The values of Return and Reason will be nonzero
only after certain SET (or overtype) failures. These
are accompanied by a message number, which you
should refer to in the
CICS Messages and Codes
manual.
