A Data Guard configuration always runs in one of three data protection modes:
- MAXIMUM PROTECTION
- MAXIMUM AVAILABILITY
- MAXIMUM PERFORMANCE (default)
All three modes provide a high degree of data protection, but they differ in terms of the effect that each has on the availability and performance of the primary database. This document attempts to provide clarification on how each work, their requirements, and how to change the protection mode of a Data Guard environment.
This document supplements the information provided in the Data Guard Concepts and Administration guide and is not a replacement.
This document is intended for Oracle Data Guard database administrators that would like to understand more about protection levels.
