This IBM® Redpaper™ publication combines Oracle Data Guard and IBM remote copy technologies and discusses the use of the near disaster and far disaster concepts that are best suited for customer environments.
The Oracle Data Guard technology is native to the Oracle database and does not depend on the server and storage replication. It requires less network bandwidth to transfer the data from a primary site to a standby site, because it transports only log files. But it is a more complex implementation when compared to storage replication and must be implemented for each database independently.
The IBM remote copy feature is a flexible data-mirroring technology that allows replication between volumes on two more disk storage systems. It does not use any server resources. Failover and failback processes are simple with the storage replication technology. It supports disaster recovery capabilities not only for the Oracle database, but for all other applications and databases within the enterprise. One disaster recovery solution can take care of all other applications, providing benefit to the customers.
The intended audience for this paper is any technical lead, system administrator, storage administrator, or Oracle database administrator in a production environment who is experienced with disaster recovery concepts and procedures. After reading this paper, the technical staff can understand how to perform failover and failback procedures on Oracle database with Automatic Storage Management (ASM) using the Data Guard methodology and IBM Metro Mirror and Global Mirror (copy services) technologies. Both technologies are explained in detail in this paper.
