Preventing, Detecting, and Repairing Block Corruption: Oracle Database 12c

Oracle Maximum Availability Architecture

Oracle White Paper 

Executive Overview

In today’s information-driven enterprises, business critical information must be highly available, from internal company-sensitive data to applications that manage crucial partner and customer relationships. Outages are costly in lost revenue and damaged reputation, and can be crippling to the business.

Block corruptions are a common source of database outages. A database block is corrupted when its content has changed from what Oracle Database expects to find. If not prevented or repaired, block corruption can bring down the database and possibly result in the loss of key business data.

This Oracle Maximum Availability Architecture (MAA) white paper presents the essential tools, techniques, and best practices to help you safeguard data and prevent corruptionrelated database outages. MAA is Oracle’s comprehensive best practices blueprint for implementing Oracle high availability technologies. The MAA best practices are described in a series of technical white papers and documentation to assist in designing, implementing, and managing optimal high availability architectures. The series of MAA white papers are available at the Oracle Maximum Availability Architecture website.

This paper is applicable to Oracle Database 12c and Oracle Database 11g Release 2.
