1.12 Interprocess Communication Resources Configuration

Interprocess communication (IPC) is a capability supported by the Windows and UNIX operating systems that allows one process to communicate with another process. On a UNIX system, you use methods native to the UNIX system to adjust the IPC parameters and maximize the performance of an Oracle Tuxedo application. Since most UNIX systems are shipped with default values that are too low for an Oracle Tuxedo application, you need to adjust the IPC parameters, using the methods given in Oracle Tuxedo 22c Release (22.1.0.0.0) Platform Data Sheets. For the recommended IPC values, see IPC Resource Configuration on a UNIX System.

After installing the Oracle Tuxedo software and creating an application configuration file (UBBCONFIG file), you use thetmloadcf(1) command to calculate and print a list of the minimum IPC resources needed to support the application. If your Oracle Tuxedo application is distributed, the minimum IPC resources must be available on every machine participating in the application. For more information about calculating IPC resources and using the tmloadcf(1)command, see Performing Post-Installation Tasks

Note:

Before installing Oracle Tuxedo software on a UNIX system, Oracle recommends that you adjust the IPC parameters on the target machine in accordance to the information mentioned in the following link, IPC Resource Configuration on a UNIX System
