ContextYou have decided to use the cluster to provide highly available services when designing or modifying the infrastructure layer.ProblemHow should you design a highly available infrastructure layer to prevent service loss due to a single server

Before you build a cluster in the Windows Server R2 DataCenter environment, you first have to failover the cluster to the Windows Server (Windows Server Failover CLuster, referred to as WSFC) has a basic understanding. WSFC must be deployed in a

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,
