Dynamic server control and automatic retry

Overview

An operator command (z/OS MODIFY command) and various BSA Service Manager functions are available for controlling the server.

Operator command

The operator command TL can be used to view a list of all ports.

BSA Service Manager

Provided that a special service port has been defined (see next paragraph), the following BSA Service Manager functions are supported:

  • Display information on users and ports.
  • Cancel a user.

Port for BSA Service Manager (BSM port)

In order to enable access from a product via the BSA Service Manager, a special service port must be defined in BSA CI. This port is known as the "BSM port" and is defined in parameter BSA_TCPIP_BSM_PORT. This keyword must also be defined with exactly the same values in the product STC from which the Service Manager is to be called. It is also possible to use the Service Manager to dynamically insert the keyword into the product beforehand. Please refer to the BSA Service Manager documentation.

Automatic retry

Automatic retry is activated when, for example, the requested TCP/IP started task is not active in z/OS, or when the connection to the task has been interrupted due to an error. Retry parameters are set using keyword Bnn_TCPIP_RETRY_INTERVAL.
