KBMMW provides a good mechanism for balancing load and disaster recovery, supports multiple implementations, and now looks at the simplest, client-controlled disaster recovery and simple load balancing.Now, we deploy Kbmmwserver to different servers, or deploy multiple instances on the same server, so we have a service

restoration process of the Oracle database is divided into two steps. First, all the retries stored in the redo log file are applied to the data file, and then all uncommitted transactions in the Redo are rolled back, in this way, all the data will be restored to the time of the disaster. Database recovery can only be used to redo data files before a fault occurs, restoring them to the time of failure, rat

minimum switching time is about 15 seconds, or even shorter. Introduction of the disaster-tolerant solution in the same city The DS8000 Metro Mirror (MM) technology is a storage-level disaster-tolerant solution that meets the Recovery point Object (RPO) of 0. In this scheme, the data is replicated to the disaster-to

mechanism, the client may read the old data in the standby node, if the business requires strong data consistency, you can set the read-only main option in the read request, so that the read request will be forwarded by the interface layer to the master node, in this case, the standby node is only used for disaster recovery, not provide services.In order to ensure the data consistency of the primary and st
