RAC维护基本命令

[grid@juliaz2 ~]$ olsnodes -i  /*显示每个节点的vip
juliaz2    juliaz2-vip
juliaz3    juliaz3-vip
[grid@juliaz2 ~]$ olsnodes -n /*显示每个节点在rac中的编号
juliaz2    1
juliaz3    2
[grid@juliaz2 ~]$ olsnodes -s /*显示每个节点状态
juliaz2    Active
juliaz3    Active
[grid@juliaz2 ~]$ olsnodes -l -p /*显示local节点的私有ip地址
juliaz2    192.168.1.22
[grid@juliaz2 ~]$ olsnodes -c   /*rac cluster的名字
juliaz-cluster

查看ORC集群中的节点及状态，这个命令位于grid infrastrcture 软件安装目录下的bin子目录，root帐号或者软件安装者都可以执行这个命令。

clusterware中的相关服务启动起来之后，vip 和scan将自动产生，并且绑定在每个公共网卡上。

clusterware中的服务的进程

crs  /crsd   /*基于OCR对集群中的资源进行管理。

css /ocssd / cssdagent  /*控制集群中每个节点的成员资格 ，ocssdagent启动和关闭ocssd进程，并监视这个进程的状态，当ocssd进程停止运行时，csssdagent负责关闭整个节点

ctss/ctssd   /*负责不同节点之间的时间同步

evm/evmd  /*当crs服务服务产生事件时，负责对事件进行处理

ohas /ohasd /*负责启动clusterware中的进程，这个进程以root用户，随系统启动而启动的。

clusterware 提供了一系列命令，这些命令都位于grid infrastrucure软件安装目录bin子目录中，用root或软件安装者都可以执行。

crs_stat一个即将被淘汰的命令：
