CEMT INQUIRE CONNECTION

If you place the cursor against a specific entry in the list and
press ENTER, CICS displays an expanded format as shown

Displayed fields

Accessmethod

displays the access method in use for this connection.
The values are:

Vtam

The connection is used for intersystem
communication (ISC).

IRc

The connection is used for multiregion operation
(MRO), and has been defined to use the
interregion communication (IRC) program for
communication. If the CONNECTION is
ACQUIRED, the MRO partner is running on the
same MVS image. If the CONNECTION is
RELEASED, the MRO partner may not be on the
same MVS image; if it is not, the XCF access
method will be used when the connection
becomes ACQUIRED.

XM

The connection is used for multiregion operation
(MRO) and has been defined to use MVS
cross-memory (XM) services for communication. If
the CONNECTION is ACQUIRED, the MRO
partner is running on the same MVS image. If the
CONNECTION is RELEASED, the MRO partner
may not be on the same MVS image; if it is not,
the XCF access method will be used when the
connection becomes ACQUIRED.

INDirect

Communication between the local CICS system
and the system defined by this connection is
through the system named in the INDSYS
operand of the connection definition.

XCf

The connection is used for multiregion operation
(MRO), and communication uses the cross-system
coupling facility (XCF) of MVS. XCF is used for
MRO links between CICS regions on different
MVS images within an MVS sysplex. It is selected
dynamically by CICS for such links when the

access method is defined as IRC or XM in the
connection definition.

RConnection

The connection is remote—that is, it is owned by
another CICS system.

Affinity (

input only field)

specifies, where CICS is a member of a VTAM generic
resource group, that VTAM is to end an affinity owned
by CICS. This option is valid only for APPC and LU61
connections. The connection must be out of service and
in NORECOVDATA state. The value is:

Endaffinity

VTAM is to end an affinity owned by CICS.

Connection(

value)

identifies this panel as relating to system connections,
and displays the 4-character name by which the
connection is known.

Connstatus

displays the state of the connection between CICS and a
remote system. The remote system can be an APPC or
an MRO partner identified by (

value) on the CEMT

INQUIRE CONNECTION command. The ACQUIRED
and RELEASED values are common to both APPC and
MRO; the others are unique to APPC. The values are:

ACquired (APPC and MRO)

The CONNECTION is acquired. The criteria for
ACQUIRED for VTAM links are:

The partner LU has been contacted.

Initial CNOS exchange has been done.

The criteria for ACQUIRED for MRO links are:

Both sides of the link are in service.

Both sides of the link are successfully logged
on to the CICS interregion communication
program (DFHIRP).

A connection request by each side has been
successful for at least one session, and
therefore each side can send and receive
data.

RELeased (APPC and MRO)

The connection is released. Although the
connection might be in service, it is not usable.

In the case of an MRO link, the released status
can be caused by any one of a number of
conditions. For example, it could be because the
CICS region on the other side has not yet
initialized, or not yet signed on to the CICS
interregion communication program (DFHIRP); or
it could be because CICS interregion
communication may have been closed on the
other side, or the connection on the other side
may have been set out of service.
