After installing grid infrastructure, RAC will focus on installing the Oracle software on the cluster. Grid infrasctructure provides a framework for running RAC, including cluster communication links, node separation, and node member relationships. ASM is the first choice for Oracle database storage.

The most outstanding performance of Oracle RAC clusters is high availability, which mainly includes load balance and failover. These technologies enable single point of failure (spof) to prevent normal access to the database by client applications, and load balancing between nodes by creating a service. This article describes the Oracle failover test in the

Generally, in the Oracle RAC environment, V $ view can query information about the instance you are connected to, while GV $ view contains information about all instances. However, in the RAC environment, when we query the V $ log view, it is common sense that the V $ log view should see the information of the log group that you connect to the instance. However,
