devices will no longer be supported in Oracle12. Oracle strongly recommends using at least 3 voting disks in a different location. When using ASM to manage voting disks, you need to be aware of the redundancy levels of disk groups and failure groups. Note that all copies of voting disk are in one disk group, and you cannot distribute voting disks across multiple disk groups. When using an externally redundant disk group, you can only have 1 voting di

undertakes read operations. This architecture is suitable for read-intensive types of applications, and read performance can grow linearly by increasing the number of Slave DB. To avoid a single point of failure in Master DB, the cluster typically uses two Master db for dual-machine hot standby, so the entire cluster has very high levels of read and write availability. In addition to providing Active Standby functionality from 11g, mysql,
