Oracle 11g two nodes RAC build a single instance DG Process Problems and Solutions I used to build a single-instance database of DG, and it was quite simple. Later I came to the company's first project to build a DG for RAC. I was confident that I was so confident that I had to go through all kinds of questions, baidu

another way to do this by directly operating the power switch. When a node fails, the other node, if detected, will be issued through the serial port command, control the power switch of the fault node, through a temporary power outage, and then fooled by the way the fault node is restarted. This approach requires hardware support.Oracle RAC uses a software approach that directly restarts the failed node. Either way, theIO fencing purpose is the same

connectivity for the clusterOne, the private networkEach cluster node is connected to all other nodes through a dedicated high-speed network, which is also known as cluster interconnect or high-speed interconnect (HSI). Oracle's cache Fusion technology uses this network to efficiently combine the physical memory (RAM) of each host into a single cache. Oraclecache Fusion allows any other instance to access this data by transmitting data stored in an Oracle

Management) mechanism. In Oracle RAC, the data is shared globally, which means that each process sees the same block of data, and the data blocks can be passed between different machines. The GRD directory structure is given.You can see that Mode, Role, and N form the basic structure of RAC lock. Mode has N, S, X3 ways Role has Local and Global two

, and each instance can receive an equal number of client requests, thus increasing the throughput as the server increases. Among the features discussed above, high availability is the largest feature of RAC. The problem with RAC is that while RAC has a number of advantages, the deployment of a RAC will involve a wid
the server procurement. More and more enterprises are willing to apply clustering solutions to their systems to reduce costs and improve system availability. Five, high throughput RAC is a logical body consisting of multiple servers that can receive more client requests than a single database server. This can be very evident in systems that require high throughput. In a

After installing grid infrastructure, RAC will focus on installing the Oracle software on the cluster. Grid infrasctructure provides a framework for running RAC, including cluster communication links, node separation, and node member relationships. ASM is the first choice for Oracle database storage.
