INQUIRE IRC
Show the IRC status.
Syntax
Activate security checks on commands by specifying the XCMD system initialization parameter and by ensuring that command security checking is active for the transaction (either by specifying CMDSEC(YES) on the TRANSACTION resource definition or by specifying ALWAYS on the CMDSEC system initialization parameter).
Conditions: NOTAUTH
NOHANDLE, RESP, and
RESP2 are common options that can be added to all EXEC CICS
commands to process error conditions. They are not explicitly included in the command syntax diagram
and option descriptions. For information about these common options and EXEC CICS
command syntax, see EXEC CICS command format and programming considerations. For more information
about the use of CVDAs, see CICS-value data areas (CVDAs).
Description
The INQUIRE IRC command indicates whether interregion communication (IRC) is open, closed, or in a transitional state in your CICS® system. IRC must be open for your CICS region to communicate with another CICS region using any of the multiregion operation (MRO) facilities (IRC, XM, or XCF).
Options
- OPENSTATUS(cvda)
- returns
a CVDA value identifying the status of IRC in the system. CVDA values
are:
- CLOSED
- IRC is closed for this system, or is not present in the system.
- CLOSING
- A SET IRC CLOSED request to quiesce MRO has been received; tasks that were already using an MRO link are being allowed to complete, but new tasks cannot use an MRO link.
- IMMCLOSING
- A SET IRC IMMCLOSE request to shut down MRO immediately has been received. Tasks that were using an MRO link are being terminated abnormally.
- OPEN
- IRC is open for this system.
- XCFGROUP(data-area)
- returns the
8-character name of the cross-system coupling facility (XCF) group of which this region is a member.
If this region is not a member of an XCF group (because it has not signed on to IRC), XCFGROUP contains the XCF group the region would be in if XCF were opened.
Conditions
- NOTAUTH
- RESP2 values:
- 100
- The user associated with the issuing task is not authorized to use this command.
