Actions required on z/OS or Windows NT

To run the EJB IVP, you need a name server that supports the Java™ Naming and Directory Interface (JNDI) Version 1.2. By default the IVP uses the lightweight tnameserv COS Naming Server that is supplied with Java 1.3 and later. To start tnameserv on the local host, enter the following command at the z/OS UNIX System Services or Windows NT command prompt:
tnameserv -ORBInitialPort 2809
This causes the name server to listen for connections on TCP/IP port 2809. If this port is already in use on your system, you will be asked to try again with a different port.
Note: If you run firewall software, by default the firewall may block your specified port. You must ensure that your firewall policy allows CICS and any EJB client applications to communicate with the name server.
