Oracle9i RAC 中quorum.dbf 及 srvm.dbf 文件了解

了解到 quorum.dbf 用于CM的检查文件, srvm.dbf 用于存放共享的数据库包括控制文件,数据文件,日志文件,归档文件,服务器配置文件(srvm configuration file) . 但是一直不太清楚里面具体存放的一些内容及如何变更,什么后台进程来这两个文件等,准备一一搞清楚,先纪录一下。


The Quorum Disk

RAC uses a quorum disk to improve cluster availability. Oracle stores cluster status

information on the partition that is reserved for the quorum disk. The node monitor uses the quorum disk configuration information to manage the cluster configuration.

The Oracle configuration and administrative tools also require access to cluster

configuration data that is stored on shared disks. You must configure a shared disk

resource to use the Database Configuration Assistant, Oracle Enterprise Manager, and the Server Control command-line administrative utility.

Note: On some platforms such as Windows NT, the quorum disk is sometimes called the voting disk.
