RAC_11g重启顺序以及常用管理命令

● 1、关闭数据库
切换至oracle用户，实验发现grid用户也可以
○ 1.1 查看数据库实例状态

[oracle@db1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node db1
Instance orcl2 is running on node db2
○ 1.2 停止所有节点上实例
[oracle@db1 ~]$ srvctl stop database -d orcl
○ 1.3 确认数据库实例状态

[oracle@db1 ~]$ srvctl status database -d orcl
Instance orcl1 is not running on node db1
Instance orcl2 is not running on node db2
[oracle@db2 ~]$ srvctl status database -d orcl
Instance orcl1 is not running on node db1
Instance orcl2 is not running on node db2
● 2、停止HAS(High Availability Services)，必须以root用户操作
○ 2.1 查看节点集群状态
切换至grid用户,查看本节点集群进程状态
crsctl check crs
#1节点
[grid@db1 ~]$ crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online

#2节点
[grid@db2 ~]$ crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4537: Cluster Ready Services is online
CRS-4529: Cluster Synchronization Services is online
CRS-4533: Event Manager is online
查看本节点集群状态

[grid@db1 ~]$ crs_stat -t -v
Name Type R/RA F/FT Target State Host

[grid@db2 ~]$ crs_stat -t -v
Name Type R/RA F/FT Target State Host

○ 2.2 停止has服务
需要在RAC的所有节点上执行，启动也一样。has与crs等同

[root@db1 ~]# find / -name crsctl
/u01/app/grid/11.2.0/bin/crsctl
[root@db1 ~]# cd /u01/app/grid/11.2.0/bin/
[root@db1 bin]# ./crsctl stop has -f

[root@db2 ~]# find / -name crsctl
/u01/app/grid/11.2.0/bin/crsctl
[root@db2 ~]# cd /u01/app/grid/11.2.0/bin/
[root@db2 bin]# ./crsctl stop has -f
其实停止HAS服务以后集群已经关停，可以查看集群状态确认，无需下面3、4步
○ 2.3 停止crs服务
需要在RAC的所有节点上执行，启动也一样。has与crs等同
[root@db1 bin]# ./crsctl stop crs -f
CRS-4544: Unable to connect to OHAS
[root@db2 bin]# ./crsctl stop crs -f
CRS-4544: Unable to connect to OHAS

○ 2.4 停止节点集群服务
停止节点集群服务，必须以root用户

[root@db1 oracle]# cd /u01/grid/11.2.0/grid/bin
[root@db1 bin]# ./crsctl stop cluster ----停止本节点集群服务
[root@db1 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 rac2
CRS-2677: Stop of ‘ora.cssd’ on ‘rac1’ succeeded
CRS-2677: Stop of ‘ora.cssd’ on ‘rac2’ succeeded

● 3 启动集群
可以单节点启动也可以双节点同时启动，下面分别介绍
○ 3.1 单节点启动
两个节点都要执行
节点1

[root@db1 bin]# ./crsctl start has
CRS-4123: Oracle High Availability Services has been started.
[root@db1 bin]# ./crsctl start crs
CRS-4640: Oracle High Availability Services is already active
CRS-4000: Command Start failed, or completed with errors.

[root@db1 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4534: Cannot communicate with Event Manager
节点2

[root@db2 bin]# ./crsctl start has
CRS-4123: Oracle High Availability Services has been started.
[root@db2 bin]# ./crsctl start crs
CRS-4640: Oracle High Availability Services is already active
CRS-4000: Command Start failed, or completed with errors.

[root@db2 bin]# ./crsctl check crs
CRS-4638: Oracle High Availability Services is online
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4529: Cluster Synchronization Services is online
CRS-4534: Cannot communicate with Event Manager

○ 3.2 所有节点启动
单节点执行即可

[root@db2 bin]# ./crsctl start cluster -n db1 db2
CRS-4690: Oracle Clusterware is already running on ‘db1’
CRS-4690: Oracle Clusterware is already running on ‘db2’
CRS-4000: Command Start failed, or completed with errors.
或者

[root@db2 bin]# ./crsctl start cluster -all
CRS-4690: Oracle Clusterware is already running on ‘db1’
CRS-4690: Oracle Clusterware is already running on ‘db2’
CRS-4000: Command Start failed, or completed with errors.
○ 3.3 检查集群状态

[root@db1 bin]# ./crs_stat -t -v
Name Type R/RA F/FT Target State Host

说明：
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

● 4、启动数据库
oracl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
○ 4.1 启动所有节点数据库实例
[oracle@db1 ~]$ srvctl start database -d orcl
○ 4.2 查看多有节点数据库实例状态

[oracle@db1 ~]$ srvctl status database -d orcl
Instance orcl1 is running on node db1
Instance orcl2 is running on node db2

○ 4.3.详细输出资源全名称并检查状态

[grid@db1 ~]$ crsctl status resource -t
