摘要：Oracle real application cluster also called Oracle RAC offers and provides very attractive and promising features for today’s challenging market scenario, where safety and availability of database is the basic need and demand of clients who are working on mission critical databases. The two most alluring features which RAC provides are high availability and load balancing. Load balancing is performed by the load balancer which most of the time works as desired; But it is noticed that failure of load balancer could be a single point of failure for the entire RAC system. In the present work our aim is to have comprehensive study of literature available in the field of monitoring the load balance in Oracle RAC in order to keep a close watch on whether switchover between nodes is happening correctly and smoothly or not. Many Researchers and developers working in this field suggested various monitoring systems for load balancing in Oracle RAC, yet there is scope to get most efficient and accurate one. The concept of relative entropy is taken as inspiration from this extensive survey of the literatures available, which will help us in comparing the randomness of the each node and also the entire RAC system. Thus entropy based monitoring system has projected as efficient system in present review work.
