Before starting the Grid infrastructure installation, we should check the private, publi,VIP, SCAN name(and SCAN IPs) are correctly configured or not. this is the best test i ever seen.

https://dbagenesis.com/p/oracle-11gr2-rac-for-beginners A computer cluster consists of a set of loosely or tightly connected computers that work together so that, in many respects, they can be viewed as a single system. Unlike grid computers, computer clusters have each node set to perform the same task, controlled and scheduled by software. The components of a cluster are usually connected to each other through fast local area networks, with each node (computer used as a server) running its own instance of an operating system. In most circumstances, all of the nodes use the same hardware and the same operating system, although in some setups (i.e. using Open Source Cluster Application Resources (OSCAR)), different operating systems can be used on each computer, and/or different hardware.

RAC environments are very complex ones and include many different components. One of the goals of RAC database is to balance the load between the different instances and listeners. In this session we will dive into the load balancing mechanism. We will talk about the client configuration, SCAN listeners, services and more, and see some guidelines and best practices to better utilize the balance between the nodes.

Oracle Database administrators have to cope with numerous challenges when migrating an existing non-cluster environment to a cluster environment. One of the most significant challenges a DBA faces is to migrate/convert an existing single instance to RAC. Oracle provides several easy methods to carry out the procedure, so it is important to know which method best fits your needs and requirements. The core objective of this presentation is to give you an overview about different methods for migrating an existing single instance to RAC, and help you find the most suitable one for your situation. The session will also explain how to perform the migration in order to minimize the downtime and to improve (speed up) the migration duration whilst dealing with VLDB.
