By: April Sims

Overview of this book

Today DBAs are expected to deploy and manage large databases with quality service and little to no downtime. The DBA's main focus is on increasing productivity and eliminating idle redundancy throughout the enterprise. However, there is no magic set of best practices or hard and fast rules that DBAs need to follow, and this can make life difficult. But if DBAs follow some basic approaches and best practices, tasks can be performed more efficiently and effectively.This survival guide offers previously unwritten underground advice for DBAs. The author provides extensive information to illuminate where you fit in, and runs through many of the tasks that you need to be watchful of, extensively covering solutions to the most common problems encountered by newcomers to the world of Oracle databases.The book will quickly introduce you to your job responsibilities, as well as the skills, and abilities needed to be successful as a DBA. It will show you how to overcome common problems and proactively prevent disasters by implementing distributed grid computing—scalable and robust—with the ability to redeploy or rearchitect when business needs change. Reduce downtime across your enterprise by standardizing hardware, software, tools, utilities, commands, and architectural components.This book will also help you in situations where you need to install Oracle Database 11g or migrate to new hardware making it compliant with a Maximum Availability Architecture. By the end of this book you will have learned a lot and gained confidence in your abilities. You will be armed with knowledge as to which tools are best used to accomplish tasks while proactively moving towards an automated environment.

Summary


This is an advanced chapter that you will need to refer back to when major changes happen within your enterprise, such as when any piece of hardware is due for replacement. There may be a way of using the older hardware (if the budget is tight) to redeploy for redundancy reasons or it may be a great way of getting your hands on a DBA-only test box.

Maximum Availability Architecture is a methodology, best practiced for maximizing the amount of uptime for your critical applications. Committing to maximizing uptime not only takes physical components but several key organizational practices to be in place. This is where the managers in your IT department need to become involved. If the organizational practices are not present in your organization, maybe it is time to speak up about their validity and importance in today's IT-centric organizations. As an Oracle DBA, you will have some pull in matters such as these. So you can take a stand for improving your situation.
