我们平常在敲入crs_stat -t命令后,对输出结果如何理解呢?这些资源的名字的后缀代表数据库的哪个组件呢?大部分可以“顾名思义”出来,下面总结一下:
[@more@]
.gsd,指的是GSD(The Global Services Daemon),Oracle的官方解释如下,The Global Services Daemon (GSD) runs on each node with one GSD process per node. The GSD coordinates with the cluster manager to receive requests from clients such as the DBCA,EM,and the SRVCTL utility to execute administrative job tasks such as instance startup or shutdown. The GSD is not an Oracle instance background process and is therefore not started with the Oracle instance.
.ons,指的是ONS(Oracle Notification Service),通信的快速应用通知(FAN:Fast Application Notification)事件的发布及订阅服务。
.vip,指的是RAC的虚拟IP地址,用于进行地址漂移的。
.db,指的是在RAC环境中建立的数据库。
.inst,指的是数据库实例。
.lsnr,指的是监听。
.srv,指的是在数据库上建立的“service”。
.asm,指的是ASM。
