RAC is an implementation of real application cluster to improve high availability through cluster. RAC can provide high-performance and low-cost solutions. RAC is based on a shared storage mechanism. Unlike Oracle database instances of a single instance, RAC provides multiple instances, each node on the cluster has its

Today, I helped my friend get a computer from a wholesaler. the built-in system is Linux, so I helped myself to build the first system, but it was always a blue screen during decompression, so I thought there was a problem with the machine. I used the employee to say that this function was restricted and only Windows 7 could be installed. Only Windows 7 systems could use the independent video card,Curiosity is stirred up, and then the human flesh begins to break the casserole and find the founda
