This is the high-quality pre-sale recommendation of Oracle class in computer >>>> "Oracle Data High Availability Road"

Editorial recommendations

This book is especially suitable for Oracle Senior system managers, application developers reading, but also for the care of server technology, data high availability and data security of enterprise technical personnel, relevant IT professional college teachers and graduate students also have important reference value.

Content Introduction

The two major issues facing modern data services are data assurance and uninterrupted service, i.e. high availability of data services (higher
availability". This book deals with Oracle's two types of solutions in this area: Data Guard and data cluster (Real application Cluster,rac). Data Guard enables data protection for the primary database by propagating data changes from the primary database to another host or hosts on the network (LAN or WAN) asynchronously or synchronously. Furthermore, the host (standby database) that follows the changes in the primary database can also implement online read-only access or temporary data read/write, which greatly enhances the application value of the data defender. RAC data cluster is to run the database at the same time on many different hosts of high-speed LAN, which can not only spread the application system's access load to different servers, but also can prevent single node failure by redundancy between multiple host services, thus providing uninterrupted data access for users. The combined application of RAC and data guard enables high availability at the highest level of the current IT industry.
This book, based on the technical principles and key knowledge points of the two types of solutions described above, provides a detailed solution to the architecture and technical roadmap of data guard and RAC in the context of enterprise application environments, including hardware and software preparation, installation configuration of Oracle systems, System management and maintenance and other content. Through a combination of the case implementation process, the reader is guided through the exciting Oracle high-availability technology.
