This book starts with the basic premise that a service is comprised of the 3Ps-products, processes, and people. Moreover, these entities and their sub-entities interlink to support the services that end users require to run and support a business. This widens the scope of any availability design far beyond hardware and software. It also increases t

"To err is human, to forgive divine," goes the familiar saying. If you have ever aspired to realize the divine within you, you need look no further - within the pages of this powerful book you will find the means to master The Magic of Forgiveness as Dada J.P. Vaswani describes it. What is forgiveness? Why should we forgive? How can forgiveness empower us, heal us, help us to bury the dead past and begin our lives anew? Answers to these and other burning questions are offered here. Dada J.P. Vaswani, whose knowledge of human nature is profound, but, at the same time, compassionate and non-judgemental, teaches us how to apologize with grace; how to forgive with generosity; how to restore damaged relationships; how to overcome resentment and bitterness; how to forgive ourselves when the need arises; and above all, how to forget after we have forgiven someone. It has been said, "We win by tenderness; we conquer by forgiveness." In this book, Dada J.P. Vaswani shows us how we may conquer ourselves - and the hearts of others - by The Magic of Forgiveness!

As our daily lives and corporate well-being become more dependent upon computers, system reliability grows increasingly important. No longer are frequent system outages acceptable. In many cases, failure intervals must now be measured in centuries. Even current fault-tolerant computing systems will fail once every five or ten years. This book is the first in a three-part series on active/active systems. It describes techniques that can be used today for extending system failure times from years to centuries, often at little or no additional cost. The techniques described include splitting a large system into smaller, cooperating independent nodes. Copies of the application's database are distributed across the nodes. It is shown that these techniques significantly reduce the number of system failure modes and increase the level of sparing. As a result, the loss of a single node's capacity occurs far less frequently than the loss of all capacity when the equivalent monolithic system fails. Furthermore, the loss of more than one node's worth of capacity is almost never. Central to these techniques is the requirement that all database copies that are distributed across the network must be kept in synchronism. Several methods available today for maintaining synchronism are described. They include asynchronous data replication, synchronous data replication, and network transactions.

The Bhagavad Gita is a world-scripture with a world message, It is not meant for India alone: it is a "Bible of Humanity". The Gita has an answer to the problems and perplexities of the modern world. The problems of social, national and international reconstruction will not be solved without an appreciation of those deeper values of life which, the Gita shows, are the very structure of Reality. A new Indian nation, a new social order, a new civilisation must be built on the essential teachings of the Gita. The wisdom of the Gita is the hope of a new humanity Sadhu Vaswani, who was regarded by many as an "embodiment of the Gita", a "living Gita", and who was equally at home in the Eastern and Western traditions of thought, gives us in this book the teaching of the Gita in simple words. In the Bhagavad Gita, simplicity is combined with wisdom. The essential teaching of the Bhagavad Gita has been overlaid by controversies which scholars and theologians may understand but not lovers of the simple life. In the present volume, the author has simplified the message of the Bhagavad Gita and related it to the experience and aspirations of the common man. "To the vast majority of men", he says, "life seems to be a meaningless muddle. Not many seem to realise that life, at its noblest, is a yatra, a piligrimage to God: the Infinite is our true Home."
