Foreword

Allow me to be the first to congratulate you for purchasing this book. Sametime 8.5 is a very different product from previous versions of the product. What once was a simple offering that provided secure instant messaging with some web conferencing capabilities has now evolved into a robust, flexible, sophisticated communications platform. This book, written from the perspective of a Domino Administrator, will help you get the most out of this platform.

For reasons I can't fully explain, the major innovations in Sametime seem to come with the dot five releases and 8.5 was no exception. Consider, for a moment, this partial list of enhancements:

Completely new Online Meetings that have been ranked as one of the best web conferencing solutions on the market.

A seamless user experience that integrates meetings into the Sametime Connect Client. Quick and easy access to meeting rooms and ability to invite others through drag and drop.

Zero-download browser access to meetings for those who prefer to operate without a rich client.

A new unified infrastructure that leverages industry standard codecs and protocols for better audio and video performance and interoperability.

Bandwidth Management tools to provide an optimal experience while protecting the network.

Standards based firewall and NAT Traversal for audio and video to make rich communications easy outside the enterprise.

The ability to replace Sametime's native audio / video with those from our partners, turning the Sametime Connect Client into first-class end points for leading room and tele-presence systems.

Telephony middlware that delivers advanced functionality (single number service, intelligent call routing, a softphone experience unqiue in the industry) regardless of the complexity of the underlying telephony infrastructure.

Zero-download browser-based instant messaging and Web 2.0 APIs to easily embed Sametime services into web apps.

Mobile clients for the latest, hottest smart phones and tablets.

A modern, flexible product architecture with consolidated management of all the components.

As Sametime has matured into a full unified communications platform, the skill set required to plan, deploy, and manage it has also evolved. Chapter 2 , Chapter 3 , and Chapter 9 will introduce you to the various servers that make up the product family. This componentized architecture is one of the ways that 8.5 is different from previous iterations of Sametime. It provides much more flexibility by allowing you to deploy more or less of any given capability to suit your specific needs. But that flexibility also requires you to make new decisions and, in conjunction with the earlier chapters, rely on Chapter 5 (planning considerations) to step you through the thought process.

Another key change to Sametime has been the migration to WebSphere Application Server (WAS) and DB2 for all new servers. WAS is a different animal from Domino and, in Chapter 4 , the authors have provided a 'Rosetta stone' for Domino admins. It is an excellent resource and well worth the time to thoroughly digest.

The remaining chapters step you through the process to install ( Chapter 6 ) and secure your environment (Chapter 7 ), customizing and delivering clients ( Chapter 10 and Chapter 11 ), integrating with other software ( Chapter 8 and Chapter 10 ) and interacting with the outside world (Chapter 9 ).

Of course, Sametime 8.5 is not the end of our journey. Just as the industry has migrated from collaboration to unified communications, social business looms on the horizon. Social forms of interaction—micro-blogging, status updates, blogs, and wikis—are rapidly becoming strategic forms of business communications. In many instances, they have taken the place of the phone call and voicemail as they provide access to knowledge when the expert isn't or can't be available. Blending social concepts with today's rich forms of communications (such as video), the explosion in mobile devices and tables (such as the iPad), new delivery and business models (such as the cloud), and managing the resulting governance and compliance challenges will be our focus as we look towards the future of Sametime.

A lot of people deserve my thanks for this book ever getting written not least Tom and Marie for asking me to work with them and showing extraordinary patience. To my friends Andrew Pollack and Rocky Oliver who encouraged me many years ago to share what I knew. Life would not be as fun without the support of some of the smartest women you could meet, the incredible Nerd Girls: Susan Bulloch, Jess Stratton, Amy Blumenfeld, Teresa Kitty Elsmore, Maureen Leland, Mary Beth Raven, Jennifer Stevenson, Marie Scott, Kathy Brown, Francie Tanner, Eileen Fitzgerald, and Kathleen McGivney. Thanks also to the Lotus Community and the many smart people in it who may not realize it but raise the bar every day, make me love what I do and who I'm lucky to call friends, especially Carl Tyler, Paul Mooney, Warren Elsmore, Bob Balaban, Chris Miller, Ben Langhinrichs, Bill Buchan, Rob Novak.

Thanks to all at Turtle but especially Mike Smith and Samuel Gee, who worked around me for 9 months without a complaint. To my parents Berry and Graham Hedley, who never gave me an option to not try my hardest at anything, I love you both.

Above all to my husband Tim Davis for his talents with a cocktail shaker in an emergency and for loving me.

For someone who never thought he would write a technical book, somehow I'm now staring at my second one. Thank you to Gabriella Davis, without whom this book would have never been started. I'm glad I was able to be a part of your first book adventure. Thank you also to Marie Scott. Apparently I didn't drive you crazy enough on the first one, as you asked me to be part of this one too. Although we need a bit of a break, I'm ready for the next idea. For all of you in my online community, thanks for being there when I needed to ask the dumb question, get pointed in the right direction, and finagle an ID and password to your Sametime server to try something out. I really couldn't do it without you. And for Susan, Ian, and Cam... I promise that I do not have another book lined up and ready to start. I vow to come out of basement more often and discover the art of face-to-face communication... Thanks for putting up with this obsession.

Acknowledgement

The essence of the Sametime product is about collaboration and communication among people and groups. As such, it is not surprising that writing a book about Sametime involves cooperation, communication, and collaboration with numerous people within our personal and professional communities.

Thank you to the team at Packt Publishing for supporting this book and for guiding the three of us through the writing process. Getting our thoughts and words organized and published will make many of our technical colleagues very happy.

We also extend our appreciation to IBM for permitting us to get a jumpstart on this book as beta users of Sametime 8.5.2, especially John Delpizzo, Lilach Ofek, David Marshak, Rob Ingram, and Avshalom Houri.

Thanks to our friends at the Turtle Partnership for use of their valuable server resources as well as our partners in crime at Lucy Sky Diamonds.

Many thanks and kudos go to the Sametime experts we called on to read and review the chapters for readability, content, and accuracy. We received valuable feedback and input on our writing and ideas from various individuals over the course of the months it took to put our words onto the page, including Paul Mooney, Susan Bulloch, Mitch Cohen, Carl Tyler, and Wes Morgan.

And as co-authors, who for most of the project were separated by multiple time zones, we may not have been quite so organized and on schedule without the use of Dropbox. It is a software that just works. And finally to our families, friends, fellow bloggers, tweeters, chat partners, Google+ Circles, and Facebook friends—we thank you for your encouragement and enthusiasm for this project. When things started to drag and we wondered where the next few pages were going to come from, you were there to remind us to keep laughing and keep going!

Preface

IBM Sametime 8.5.2 delivers a state-of-the-art enterprise-ready instant messaging, meeting, and conferencing service. This Administrator's Guide navigates through the range of Sametime server components and features, providing you with the essential information required to install, administer, and troubleshoot your Sametime 8.5.2 environment. The IBM Sametime 8.5.2 Administration Guide cuts through the complexity of architecting, installing, and administering all the moving parts of the latest version of Sametime.

With this book, you will have all the information necessary to decide which server components provide the features you need as well as how to install them to get the most performance and maintainability from the software. Starting with an overview of Sametime 8.5.2, you will then dive into each server component, learning what each one does, why it might be needed in your environment, and what you need to have in place to run it. By the end, you will be able to have Sametime running and configured properly for your particular situation. With flexibility comes complexity—but not with this guide. You will learn how different architectures are possible and how to prepare properly for the installation of Sametime. You will learn how to install the servers in the right order so that you can maintain and expand your environment in the future. You will also find out how best to monitor your Sametime environment for issues, as well as how to effectively troubleshoot those problems so that you can quickly get Sametime running again.

The IBM Sametime 8.5.2 Administration Guide is the perfect one-stop resource for learning important installation and configuration details quickly and easily.
