Research on Deployment Technology of Oracle Database 4-Node Rac in Power Consumption Information Acquisition System

With the increasing load of the Power Consumption Information Collection System, the high CPU rate of the two-nodes Oracle RAC system lasts for a long time, and the use of 100% CPU appears often, this appearance seriously infected the stability of our system. Under the condition of the former resources cannot be increased, we consider to add two cluster nodes to share some part of business load, the load will be transferred to the new two nodes, and then the CPU rate of the database servers will be reduced. At last our Power Consumption Information Collection System will be stable to provide services. In this paper, the way of four-nodes Oracle RAC is studied and explored for the Power Consumption Information Collection System.
