Overview

The service port is used for the internal communication between the product server and the product application, for example, to process specific service and administration requests.

• The BSA Service Manager uses the service port to provide ISPF online information on the operating status of BSA CI, and to enable the operating status to be modified.
• The product server uses the service port for SSL communication with a product client agent to process specific administrative tasks.

Assigning the service port

The service port is assigned to an application port of the BSA CI using the LST parameter Bnn_TCPIP_SSL_PORT_app.

Security

The port can be protected by a firewall, and it is possible to ensure that the port can only be used by authorized servers. To do so, use the LST parameter Bnn_TCPIP_SERVICE_IPA[_app].

The inherent security is that the port only processes the requests that are sent by one or more previously defined IP addresses.

The IP address (ipa) stands for the relevant z/OS system where the z/OS product server concerned is active.
