【关闭集群顺序】

1.使用crs_stat 命令查询RAC节点的服务状态是否正常[grid@ora01sh ~]$ crs_stat -t -v2.使用srvctl (service control)命令依次关闭集群服务关闭顺序：关闭数据库(实例)-->关闭ASM实例-->关闭节点服务1)关闭数据库[grid@ora01sh ~]$ srvctl status database -d rac--关闭数据库srvctl stop database -d rac1srvctl stop database -d rac2--关闭各节点ASM实例[grid@ora01sh ~]$ srvctl status asm -n ora01shASM is running on ora01sh[grid@ora01sh ~]$ srvctl status asm -n ora02shASM is running on ora02sh

srvctl stop asm -n ora01sh

srvctl stop asm -n ora02sh

[grid@ora01sh ~]$ crs_stat -t -v

关闭各节点服务：listener、gsd、ons、vip

[grid@ora01sh ~]$ srvctl status nodeapps -n ora01shVIP ora01sh-vip is enabledVIP ora01sh-vip is running on node: ora01shNetwork is enabledNetwork is running on node: ora01shGSD is disabledGSD is not running on node: ora01shONS is enabledONS daemon is running on node: ora01sh

[grid@ora01sh ~]$ srvctl status nodeapps -n ora02sh

VIP ora02sh-vip is enabledVIP ora02sh-vip is running on node: ora02shNetwork is enabledNetwork is running on node: ora02shGSD is disabledGSD is not running on node: ora02shONS is enabledONS daemon is running on node: ora02sh

srvctl stop nodeapps -n ora01sh

srvctl stop nodeapps -n ora02sh

【启动集群顺序】

启动顺序：启动节点服务-->启动ASM实例-->启动数据库实例1)启动各节点的服务srvctl start nodeapps -n ora01shsrvctl start nodeapps -n ora02sh2)启动ASM实例srvctl start asm -n ora01shsrvctl start asm -n ora02sh3)启动数据库及实例[grid@ora01sh ~]$ srvctl status instance -d rac -i rac1,rac2Instance rac1 is running on node ora01shInstance rac2 is running on node ora02sh

[grid@ora01sh ~]$ srvctl status database -d rac

Instance rac1 is running on node ora01shInstance rac2 is running on node ora02sh

[grid@ora01sh ~]$ crs_stat -t -v
