Label: The loadbalance is to distribute the load evenly to each node in the cluster, thus improving the overall throughput capacity. The Oracle 10g RAC provides two different ways to spread the load: 1. By connection balancing, the user is assigned to a different node according to an algorithm. It can also be considered as a decentralized load of pure technology.

In an application environment, all servers use and manage the same database to distribute the workload of each server. The hardware requires at least two services.

In general, Oracle 11g R2 RAC provides the following features: High Availability: shared-everything mode ensures that services are not stopped when a single node fails, and other nodes in the cluster will take over quickly Scalability: multiple nodes share the load and can provide processing capabilities far beyond that of a single database. Addition and dele

In the Oracl RAC 10.2.0.4 environment where the operating system is Linux, the local hard disk of a node server is suddenly damaged and stops running. The remaining node still works normally and continues to provide external database services. The problem is clear. After the operating system retries, how can I add a server with damaged hard disk to the RAC cluster
