Combining high-availability and disaster recovery: Implementing Oracle Maximum Availability Architecture (MAA) on Oracle 10gR2 RDBMS
نویسنده
چکیده
Increasing dependence of business on 24/7 IT systems sets requirements to support recovery from hardware, software and operational errors and reduce number and length of maintenance windows through online and automated or semi-automated system management activities. These requirements cannot be satisfied purely by technology let alone a single technological innovation on a single layer of a system stack. Oracle has defined Maximum Availability Architecture (MAA) to describe the combination of its technologies to support recovery from hardware, software and operational errors. With regard to the Oracle RDBMS, these extend the online and automated management features of the RDBMS. This paper reviews the MAA on Oracle RDBMS with particular focus using Linux as platform to implement the MAA. The paper also provides a threat analysis to review the extent and limitations of MAA-based implementation high-availability and disaster recovery capabilities.
