CORBA 2.3.3 Administration Guide (NonStop CORBA 2.3.7+)

port_number 0
tcp_server true
host_name localhost
Assigning a port number of 0 causes NonStop CORBA to assign an available port to each new server.
NonStop CORBA Listening on the Wrong Socket
Problem: The CORBA server process is running, but the scf show status command shows that the server is not
listening on the correct socket. The client program gets the COMM_FAILURE error message.
Solution: To ensure that the CORBA server is using the correct TCP/IP process for communication with the client, add a
DEFINE to your environment with the following command, specifying the correct TCP/IP process name in place of $ZTC0:
add_define =TCPIP^PROCESS^NAME class=map file=\$ZTC0
To determine the correct TCP/IP process name for the system and IP address you use, see the example of scf info
subnet in Verifying TCP/IP Configuration.
If the server is running under TS/MP, add the following defines to the TS/MP configuration:
SET SERVER DEFINE =TCPIP^PROCESS^NAME, CLASS MAP, FILE $ZTC0
SET SERVER DEFINE =TCPIP^HOST^FILE, CLASS MAP, FILE $SYSTEM.ZTCPIP.HOSTS
Explanation: The NonStop CORBA server uses the TCPIP process environment variable to manage the TCP/IP socket
connection. If the TCPIP process name is not defined with =TCPIP^PROCESS^NAME, the client cannot establish a
connection to the server.
Event Channels Do Not Work
Problem: When NonStop CORBA application that uses Event Channels on OSS, the application fails to resolve an Event
Channel object.
Solution: Verify the problem by running the sample CORBA program event_service, in the javasamples directory. Update
NonStop CORBA T0539B11 with the AAA IPM (released 6-25-2001), or use a more recent release of NonStop CORBA.
Explanation: In the version of NonStop CORBA released on 4-11-2001, the Event Service does not work correctly. Therefore
any Java program that tries to use the Event Service fails. The related Genesis case (10-010611-4985) was addressed by AAA
IPM for NonStop CORBA T0539 B11, released 6-25-2001.
