Oracle 11gR2 RAC 集群服务启动与关闭总结
引言：这篇文章主要是介绍了 Oracle RAC 集群服务的启动与关闭顺序，很多初学者不太理解 RAC，对 RAC 知识了解甚少，对其启动与关闭的顺序和原理不是特别清晰。因此分享了这篇文章，感谢原作者辛苦的付出，更加地感谢大家对此篇文章的浏览。
用oracl用户执行srvctl命令
语法：srvctl stop database -d dbname ［-o immediate］作用：可以一次性关闭dbname的所有实例[oracle@rac1 ~]$ srvctl stop database -d racdb -停止所有节点上的实例然后查看状态：
[oracle@rac1 ~]$ srvctl status database -d racdb Instance rac1 is not running on node rac1Instance rac2 is not running on node rac22.停止HAS(High Availability Services)，必须以root用户操作
[root@rac1 oracle]# cd /u01/grid/11.2.0/grid/bin[root@rac1 bin]# ./crsctl stop has -f[root@rac1 bin]# ./crsctl stop crs -f本命令只能关闭当前节点的CRS服务，因此需要在RAC的所有节点上执行，启动也一样。has与crs等同3.停止节点集群服务，必须以root用户：
[root@rac1 oracle]# cd /u01/grid/11.2.0/grid/bin[root@rac1 bin]# ./crsctl stop cluster ----停止本节点集群服务 [root@rac1 bin]# ./crsctl stop cluster -all ---停止所有节点服务也可以如下控制所停节点：
[root@rac1 bin]# crsctl stop cluster -n rac1 rac2CRS-2677: Stop of 'ora.cssd' on 'rac1' succeededCRS-2677: Stop of 'ora.cssd' on 'rac2' succeeded。。。。。。。。。。。省略日志输出。。。。。。。。。。。。。。你如果想一条命令把所有的进程全部停止可以使用上述命令。如果不指定参数的话对当前节点有效，如果指定参数的话对相关参数节点有效。
4.检查集群进程状态
[root@rac1 bin]# crsctl check cluster详细输出[root@rac1 bin]# crs_stat -t -v只检查本节点的集群状态[root@rac1 bin]# crsctl check crs单一节点启动
[root@rac2 ~]# crsctl start has [root@rac2 ~]# crsctl start crs[root@rac2 ~]# crsctl check crsCRS-4638: Oracle High Availability Services is onlineCRS-4537: Cluster Ready Services is onlineCRS-4529: Cluster Synchronization Services is onlineCRS-4533: Event Manager is online所有节点启动[root@rac1 bin]# crsctl start cluster -n rac1 rac2CRS-4123: Oracle High Availability Services has been started.[root@rac1 bin]# crsctl start cluster -all[root@rac2 ~]# crsctl check clusterCRS-4537: Cluster Ready Services is onlineCRS-4529: Cluster Synchronization Services is onlineCRS-4533: Event Manager is online此命令会在后台启动所有 RAC CRS 相关进程[root@rac2 ~]# crs_stat -t -vCRS-0184: Cannot communicate with the CRS daemon.因为 start has 启动的 crs 进程比较多因此会启动的比较慢，我的机器等待了 5 分钟，在没有完全启动成功之前会报上述错误，需要耐心等待一段时间后执行下面命令即可查看到所有 CRS 相关进程服务已经启动。Name Type R/RA F/FT Target State Host

英文解释
ora.gsd is OFFLINE by default ifthere is no 9i database in the cluster.ora.oc4j is OFFLINE in 11.2.0.1 as DatabaseWorkload Management(DBWLM) is unavailable. these can be ignored in11gR2 RAC.中文解释ora.gsd 是集群服务中用于与 9i 数据库进行通信的一个进程，在当前版本中为了向后兼容才保存下来，状态为 OFFLINE 不影响 CRS 的正常运行与性能，我们忽略即可
ora.oc4j 是在11.2.0.2 以上版本中有效的服务进程，用于 DBWLM 的资源管理，因此在11.2.0.1 以下版本并没有使用
oracle 用户执行 srvctl 命令：
语法：srvctl start|stop|status database -d dbname ［-o immediate］作用：可以一次性启动 dbname 的所有实例[oracle@rac1 ~]$ srvctl start database -d racdb -启动所有节点上的实例然后查看状态：[oracle@rac1 ~]$ srvctl status database -d racdb3.详细输出资源全名称并检查状态
crsctl status resource -tcrsctl status resource4.常用 srvctl 命令指定 dbname 上某个实例
srvctl start|stop|status instance -d -i5.显示 RAC 下所有实例配置与状态srvctl status|config database -d6.显示所有节点的应用服务（VIP，GSD，listener，ONS）srvctl start|stop|status nodeapps -n7.ASM 进程服务管理srvctl start|stop|status|config asm -n [-i ] [-o]srvctl config asm -asrvctl status asm -a8.可以获取所有的环境信息：srvctl getenv database -d [-i]9.设置全局环境和变量：srvctl setenv database -d -t10.在 OCR 中删除已有的数据库信息srvctl remove database -d11.向 OCR 中添加一个数据库的实例：srvctl add instance -d -i -n srvctl add instance -d -i -n12.检查监听的状态srvctl status listener srvctl config listener -aSCAN 配置信息srvctl config scanSCAN listener 状态信息srvctl status scansrvctl 命令是一个服务级别命令，可以对单一服务资源进行统一启动、停止等管理操作
