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.

  • Update environment variables (Linux and Unix systems only)—from Chapter 2, Maintaining Oracle Standards, only need to edit a configuration file instead of a multitude of scripts.

  • Upgrade the recovery catalog—already done earlier according to step-ordered approach.

  • Upgrade Automatic Storage Management (ASM)—step-ordered approach is to upgrade ASM instance (different home) before any databases, keeping it at the same compatible level. After all databases serviced by this ASM are migrated to 11g, then advance the ASM compatible parameter to 11g to enable the new features.

  • Add new features as appropriate—wait at least a week before changing any database parameters...
