CEMT SET TCPIPSERVICE
|
CEMT SET TCPIPSERVICE
| Function: Modify the status of a service using CICS
| internal TCP/IP support
| Description: SET TCPIPSERVICE allows you to update
| the information relating to a service which uses CICS internal
| TCP/IP support.
| Note: This command has no effect on the sockets support
|
provided by the TCP/IP for OS/390 CICS Sockets
| 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
| is CEMT S TCPIPS ). You get a display that lists the
| current status, similar to that obtained by CEMT
| INQUIRE TCPIPSERVICE. You can then tab to the
| highlighted or blank fields and overtype them with the
| required values.
| Type CEMT SET TCPIPS ( CEMT S TCPIPS ) with ( value) or
| ALL, followed by one or more attribute settings that you
| wish to change. For example, cemt s tcpips status
| open opens CICS internal sockets support.
| Typing ? at the beginning of either the first or second line
| gives a syntax prompt. Resetting the values takes effect
| immediately.

| 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.
