CEMT SET CONNECTION

CEMT SET CONNECTION

Function:

Change the status of connections linked to

specific terminals.

Description:

When a connection has been defined as

INDIRECT, no information is given unless the direct
connection to which it refers is installed.

If you want to install a new connection definition when one is
already installed, you must set the connection OUTSERVICE
and, if it is VTAM-connected, release it before using the
CEDA INSTALL commands for your new definition. See the
CICS Resource Definition Guide for further information about
connections.

Syntax:

Press the Clear key to clear the screen. There are

two ways of commencing this transaction:

Type

CEMT SET CONNECTION

(the minimum abbreviation is

CEMT S C

) followed by one or more connection identifiers

or ALL. You get a display that lists the current status,
similar to that obtained by CEMT INQUIRE
CONNECTION. You can then tab to the highlighted or
blank fields and overtype them with the required values.

Type

CEMT SET CONNECTION

(

CEMT S C

) followed by one

or more connection identifiers or ALL, followed in turn by
one or more attribute settings that you wish to change.
For example,

cemt s c al i

resets the values for all

connections to make them available for use (inservice).

Typing ? at the beginning of either the first or second line
gives a syntax prompt. Resetting the values takes effect
immediately.

Options

(

value)

One or more names (1–4 characters) defined for an
interregion communication (IRC) or an intersystem
communication (ISC) connection.

ACquired (

appc only)

specifies whether CICS is to acquire a session with the
logical unit represented by the CONNECTION name. To
get more detailed information about the availability status
of the connection elements, use the CEMT INQUIRE
MODENAME command. A connection cannot be both
ACQUIRED and OUTSERVICE.

ALl

Any changes you request are made to all resources of
the specified type that you are authorized to access.

Backout (APPC parallel-session, CICS-to-CICS MRO, and

LU61 only)
All UOWs shunted due to the failure of this connection
are to be backed out. The normal resynchronization
process is to be partially overridden: decisions are taken
for any units of work that are in-doubt due to a failure of
the connection; but the decisions are recorded and any
data inconsistencies are reported when the connection is
next acquired.

CAncel

Automatic initiate descriptors (AIDs) queuing for the
specified connection are to be canceled.

AIDs representing scheduled and allocated requests
waiting in the local CICS system for the specified
connection are canceled. However, TD AIDs with an
associated triggered task already started are not be
canceled. In addition, the following CICS system AIDs
are not purged unless FCANCEL is specified.

When a canceled SCHEDULE request is found to have
a precursor in a remote CICS system; that is, the AID
was originally scheduled in a remote system, the remote
AID is canceled asynchronously.

Message DFHTF0100 is written to CSMT to indicate
how many AIDs have been deleted for the connection
and how many remain.

An ‘AIDS CANCELED’ message appears on the CEMT
panel whenever AIDs are deleted using the CANCEL
option of the CEMT SET CONNECTION command.
