|

Feature.

Syntax:

Press the Clear key to clear the screen. There are

| two ways of commencing this transaction:

Type

CEMT SET TCPIPSERVICE

(the minimum abbreviation

). You get a display that lists the

|

current status, similar to that obtained by CEMT

|

INQUIRE TCPIPSERVICE. You can then tab to the

|

required values.

Options

| BACKLOG
|

changes the maximum number of requests which can be

|

queued in TCP/IP waiting to be processed by the

|

service. The service must be CLOSED before you can

|

change this value. If you set BACKLOG to zero, CICS

|

does not receive any connections.

| Status
|

Changes the status of the service. CVDA values are:

|

OPEN

CICS internal sockets support is to start

|

listening for incoming requests on the

|

specified port.

|

CLOSE

CICS internal sockets support is to stop

|

listening for incoming work on the specified

|

port. All active tasks using this service are

|

allowed to complete.

|

IMMCLOSE CICS internal sockets support is to stop

|

listening for incoming work on the specified

|

port immediately. Any active tasks using this

|

service are terminated abnormally.

| URM
|

specifies the 8-character name of the program to be

|

used as the Service User-replaceable module by the

|

attached task. You can specify either an installation

|

specific program or the CICS-supplied default for the

|

service.

|

Note: This program and any programs it invokes must

|

be installed before they can be used in the

|

program autoinstall process. You can do this

|

either with explicit PROGRAM definitions or by

|

autoinstall when some other autoinstall program

|

is in force. Otherwise the program autoinstall

|

process fails when it is next used, and CICS

|

makes it inactive.
