CORBA 2.6 Programmer's Guide for C++

You can also use the two alternatives in combination if you need more than sixteen Comm Server

processes.

Using Multiple Instances of NonStop TCP/IP

If the TCP/IP process is a performance bottleneck, you can increase the number of external port

connections available to your application by doing the following:

Add multiple instances of NonStop TCP/IP to your NonStop CORBA system.1.

Assign your Comm Server processes, and also any application processes that are direct TCP

servers, to multiple TCP/IP processes.

For TCP/IP configuration details, refer to the TCP/IP Configuration and Management Manual or the

TCP/IP (Parallel Library) Configuration and Management Manual.

Using Multithreaded Servers

If your server performs thread-blocking operations, writing a multithreaded server allows you to increase

concurrency without incurring extra process-creation overhead. For more information about

multithreading in NonStop CORBA applications, see Writing Multithreaded Applications.

However, if your server performs process-blocking operationssuch as accesses to NonStop SQL

databasesmultithreading will not help. In such cases, you can:

Configure your server as a server pool, as discussed under Using Server Pools.●

Redesign your application to isolate the process-blocking operations, as discussed under Designing

Advanced Applications.
