The Tuxedo administrator has to set up some of the environment so the Tuxedo Application Servers can be deployed. The following section details some of these tasks.
The Oracle Tuxedo subsystem uses semaphores, message queues, and shared memory Interprocess Communication resources provided by the UNIX operating systems. UNIX systems often benefit from customization of kernel parameters associated with these IPC resources.
The names and recommended values for IPC tuning parameters may vary depending on the operating system vendor and the specific release. See the Oracle documentation for information on configuring UNIX kernel parameters for the Oracle Tuxedo system.
It is important to consider the message queue parameters MSGMAX and MSGMNB. CA Gen Tuxedo applications support data transfers up to 32 KB in size. This 32 KB buffer size should be considered when adjusting these two kernel parameters.
