Question

oracle rac中的'ora.node1.gsd' 是什么服务

Answer 1

oracle官方文档的描述

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.

GSD与rac的管理工具dbca srvctl oem进行交互，用来完成实例的启动关闭等管理任务。
为了保证这些管理工具运行正常必须在所有的节点上先start gsd,并且一个GSD进程支持在
一个节点的多个rac.gsd进程位于$ORACLE_HOME/bin目录下，其log文件为$oracle_home
/srvm/log/gsdaemon.log

追问

也就是说gsd是oracle用来图形化界面管理的一个接口的后台服务?这个进程不是很重要的?
