CORBA 2.3.3 Administration Guide (NonStop CORBA 2.3.7+)

The server is running in a TS/MP server pool and your object is associated with a POA that has a
stateful policy.
●
When your server produces object references that specify the file-system protocol, the process name is
included as part of the object references. Later, clients using the object reference make requests and those
requests are directed to the identically named process. For this reason, the server process must run as a
named process.
The POA lifespan policy also affects file-system object references:
Lifespan Policy Effect
Transient
Only the process instance that produced the object reference can subsequently service
it. Thus if your server restarts, the transient object reference is no longer valid even
though the restarted process has the same name as the original process.
Persistent
A restarted process that has the same name as the original process can service the
request.
IIOP Protocol
Enable the IIOP protocol when you want TCP/IP to be used as the transport mechanism for requests and
responses. A server in which the IIOP protocol is used can be configured as a direct server or an indirect
server. A direct server listens directly to the TCP/IP port. An indirect server listens to the port by means
of the Comm Server, which forwards requests to the actual server process.
To configure a direct server, define the server profile as follows:
Set use_comm_server to false.1.
Specify the server's host name and port number in the program profile. Give the host name as
either an IP address in dot decimal form or as a name that can be resolved to an IP address.
2.
Specify the port numberthe TCP/IP port number on which the server process listens for requests.
The value zero causes the ORB component to automatically choose a port number.
3.
(Optional) Specify the TCP process. The TCP process must be one that can service requests
directed to the host name's IP address.
4.
To configure an indirect server, define the server profile as follows:
Set use_comm_server to true.1.
Use the Pathsend protocol or the file system protocol.2.
The following table shows the keys and values that are associated with the IIOP protocol
