41.	What are the performance views in an Oracle RAC environment?
	Oracle offers dynamic performance views which are called v$ views. These views are available in a single instance as well as RAC databases. However, these views contain information about current instance only. The global version of these views is called gv$ views. These views collate information from the v$ view on each node in RAC and provide comprehensive information for all the nodes from a single node.
