Defining name servers

You might need to define name servers for two purposes:

  1. If you are using Domain Name system connection optimization, the listener regions need to be configured to talk to the same name server on z/OS® that the MVS™ Workload Manager is configured to use.

    You can define the name server to be used by TCP/IP by providing a SYSTCPD DD statement in the CICS startup JCL for the listener region, as described in CICS® Transaction Server for z/OS Installation Guide.

  2. A client application can locate an IIOP server application using object references that have been registered in a name server. For example, a Java™ client can use the JNDI interface to obtain a reference to a server application object such as an instance of the home interface of an enterprise bean. Object references can be registered in a name server from CICS by issuing the commands PERFORM CORBASERVER PUBLISH, or PERFORM DJAR PUBLISH.
