Administering the RPC Server for CICS Socket Listener using the Command Central GUI

This document describes how to administer the EntireX RPC Server for CICS® Socket Listener, using the Command Central graphical user interface. It covers the following topics:

See also Administering the RPC Server for CICS Socket Listener using the Command Central Command Line. The core Command Central documentation is provided separately and is also available under Guides for Tools Shared by Software AG Products on the Software AG documentation website.

Logging in to Command Central

Open an Internet browser and specify the URL of the Command Central Server as follows: http://<Command_Central_host>:<Command_Central_port>. This takes you to the Command Central Login page.

On Windows you can also get to the Login page from the Command Central Start Menu entry.

Provide your user credentials in the Login page and click Log In. This takes you to the page Home > Instances:

Here you can modify the CICS Socket Listener specific parameters. As a prerequisite, the CICS Socket Listener must be installed. See Preparing for CICS Socket Listener.

Parameter Description
Connection
Transport Use TCP or SSL to communicate with CICS Socket Listener.
CICS host Hostname of CICS Socket Listener.
CICS port CICS Socket Listener Port.
CICS transaction ID Required. Transaction ID (1-4 characters) defined for the RPC CICS RFE. Default is XRFE.
CICS encoding Specify the appropriate EBCDIC encoding used by your CICS Socket Listener. Default is codepage cp037 with full Latin-1 character set.
CICS SSL trust store Specifies the location of the SSL trust store.
CICS SSL trust password The password of the SSL trust store.
CICS SSL verify server The RPC server as SSL client checks the identity of CICS Socket Listener as SSL server.
CICS socket timeout Socket timeout (in seconds).
Credentials
RACF user ID The user ID (max. 8 chars) as defined in your underlying mainframe security system (e.g. RACF).
RACF password Password/passphrase as defined in your underlying mainframe security system (e.g. RACF).
Use PassTicket (1) Use PassTicket instead of password.
Application name Required if PassTicket is to be used instead of a password. Application name (1-8 chars) as defined in your RACF system. This property is ignored if RACF password is set.

Notes:

  1. By default, PassTickets can only be used once during a one-second time interval. They are protected against replay. This limits the workload to one request per second.

    Warning:
    IBM provides a mechanism to bypass the PassTicket's replay mechanism, allowing higher workloads, but this introduces security risks. The option to bypass the PassTicket's replay mechanism should only be used in secure environments where access to generated PassTickets is limited to a secure or internal network. See your IBM documentation for more information.
