What’s Inside This Book This book is about the Oracle technologies that are provided with Oracle Database 11g Release 2 and Oracle Clusterware to help achieve a highly available end-user experience. We have grouped these technologies into four parts: ■■ Grid Infrastructure Laying the foundation for Maximum Availability ■■ Oracle Real Application Clusters Building on this foundation at the database layer xxxi xxxii Oracle Database 11g Release 2 High Availability ■■ Disaster Planning and Recovery Expanding availability beyond the data center ■■ Enhancing Availability with Additional Features Grid Infrastructure With Grid Infrastructure 11g Release 2, Oracle Automatic Storage Management (ASM) and Oracle Clusterware are installed into a single home directory, which is referred to as the Grid Infrastructure home.

Availability requisites such as rolling patch upgrades, dropping nodes, and adding nodes, and policy-managed databases are discussed. Chapter 8 takes more of an application viewpoint of the Oracle RAC database.

In days gone by, Max often found that he needed to perform an entire database restore to recover up to the time just prior to the occurrence of some critical error (such as an inadvertent deletion of data, some other logical corruption, or corruption of an online redo log).
