In RAC, each cluster node has and has only one individual ASM instance. When started, each instance detects ASM disk group resources in the grid infrastructure through initialization parameters in the cluster software. Each ins

If you configure the Remote_listener parameter, the Pmon process can not only register the load information to the local listener, but also register to the listener of other instances. With the Pmon autoenrollment mechanism, the listener of each node in the cluster has the load information of all nodes, and when the client request is received, the connection is assigned to the

ORACLE RAC principle in an application environment, all servers use and manage the same database in order to spread the workload of each server, requiring at least two more servers on the hardware, and a shared storage device. It also requires two types of software, one is cluster software, the other is the RAC component in the
