Getting Started with Oracle Tuxedo

Overview of this book

The client server or Tuxedo has existed for the past few decades and it is expanding every day! Today, Service Oriented Architecture (SOA) or Service Component Architecture (SCA) are considered to be the new approaches to build client server architecture, Tuxedo adopts this concept and can be extended very easily. "Getting Started with Oracle Tuxedo" shows how to develop distributed systems using Tuxedo and extend that to SOA or even a Cloud environment. The primary objective of this book is to show how to develop distributed systems using Tuxedo and extend that to a SOA environment. It also gives fundamentals of Exalogic machines and how Tuxedo application can leverage these new high end machines for enterprise needs. This book introduces you to the client server technology and how it has evolved in past decades. The book also covers various Tuxedo installation procedures, hardware and software requirements, and then how to configure Tuxedo application, all parameters with their syntax and relevant values. You will be introduced to various Tuxedo administrative tools, which are very important for a Tuxedo Administrator to perform his daily work, and with tuning suggestions and best practices. Next comes, Tuxedo APIs to build your applications, combining client and server modules. The book then covers the SALT component, which allows external web service applications to invoke Tuxedo services, and similarly Tuxedo applications can invoke external web services. At the end we discuss briefly the Exalogic machine and its architecture and how to configure and deploy Tuxedo application in this environment.

Tuxedo configuration and runtime


We know how to configure various Tuxedo components quite well by now, so in this section we will discuss only the configuration relating to an Exalogic machine.

The UBBCONFIG file

In this section, we will discuss all the configuration related tasks using the UBBCONFIG file. We will be introduced to some more parameters in the UBBCONFIG file and some environment variables that need to be set for running Tuxedo on an Exalogic box. In MP mode, communication between two nodes is done through a bridge, but in Exalogic's cross-node, communication can be leveraged using remote direct memory access (RDMA). You need to specify RDMA with option values in the MACHINES section; there are four options, which are as follows:

  • RDMADAEMONIP: This is the IP (IPoIB ) address, but it is not an Ethernet-based IP address, and the Msgq_daemon process is bound with it. You need to configure a one-to-one configuration for Msgq_daemon and the logical machine.

  • DMADAEMONPORT: This is a...
