1.9 Hardware and Software Prerequisites

The Oracle Tuxedo software must be installed on each server machine that participates in an Oracle Tuxedo application, also known as a Tuxedo domain. A Tuxedo application is a business software program, built upon the Tuxedo system, which is defined and controlled by a single configuration file known as the UBBCONFIG file. The Tuxedo configuration file is described on reference page UBBCONFIG(5) inFile Formats, Data Descriptions, MIBs, and System Processes Reference.

A Tuxedo application consists of many Tuxedo system processes, one or more application client processes, one or more application server processes, and one or more computer machines connected over a network. In a multi-machine Tuxedo application running different releases of the Oracle Tuxedo software, the master machine—designated via the MASTER parameter in the RESOURCES section of the UBBCONFIG file—must run the highest release of the Oracle Tuxedo software in the application. For more information about Tuxedo applications, see “Domains” in Oracle Tuxedo Product Overview.

Note:

• Oracle advises against trying to share the Oracle Tuxedo system executables across remote filesystems; this practice has proven to be unreliable in the past.
• Before installing Oracle Tuxedo software on a UNIX system, Oracle recommends that you repartition your hard disk device in accordance to File and Database Management and Disk Space Allocation.
