启停RAC

–asm 自动挂载
alter system asm_diskgroups=‘ORADATA,ORAFLASH,ORAIMAGE1,ORAIMAGE2,ORAIMAGE,VOT01’ scope=spfile;
alter system set asm_diskstring=’/dev/oracleasm/disks/*’ scope=spfile;

1. 检查节点集群资源状态（grid用户）：crs_stat -t

或者crsctl stat res -t
停止顺序：数据库–》ASM–》节点服务–》集群软件==================
1.停止监听（oracle执行）：
srvctl stop listener -n node1
srvctl stop listener -n node2

srvctl status listener -n node1

srvctl start listener -n node1
srvctl start listener -n node2

-------不执行
srvctl stop vip -n node1
srvctl stop vip -n node2
-------不执行
srvctl stop scan_listener -n node1
srvctl stop scan_listener -n node2

grid 用户
srvctl stop listener

2. 停止em(oracle执行):
   emctl stop dbconsole

3.停止实例（oracle执行）：
srvctl stop instance -d orcl -i orcl1
srvctl stop instance -d orcl -i orcl2
or
srvctl stop instance -d orcl -n node1
srvctl stop instance -d orcl -n node2
or
srvctl stop database -d orcl

4. 停止asm(grid执行):
   srvctl stop asm -n node1
   srvctl stop asm -n node2

5. 停止nodeapp(oracle执行)：
   srvctl stop nodeapps -n node1
   srvctl stop nodeapps -n node2

6.root用户停止集群软件
/etc/init.d/init.crs stop
OR
[root@node1 ~]# cd /home/g01/app/11.2.0.4/grid/bin/
[root@node1 bin]# ./crsctl stop crs
(crsctl stop has -f )
==========================启动顺序：节点服务–》ASM–> 数据库实例—》集群软件--------------------------------------------------
1.
启动nodeapps:
srvctl start nodeapps -n node1
srvctl start nodeapps -n node2

启动asm:
srvctl start asm -n node1
srvctl start asm -n node2

3. 启动数据库实例
   srvctl start database -d orcl
   or
   srvctl start instance -d orcl -i orcl1
   srvctl start instance -d orcl -i orcl2
   or
   srvctl start instance -d orcl -n node1
   srvctl start instance -d orcl -n node2

6.root用户启动集群软件
/etc/init.d/init.crs start
or
cd /home/g01/app/11.2.0.4/grid/bin/
crsctl start crs
(crsctl start has )
4.
启动监听：
srvctl start listener -n node1
srvctl start listener -n node2

启动vip
srvctl start vip -n node1
srvctl start vip -n node2

启动scan_listener:
srvctl start scan_listener -n node1
srvctl start scan_listener -n node2

----监听intermediate状态，处理
srvctl stop listener -n node2
srvctl stop scan_listene
ps -eaf|grep tns ##kill -9 掉进程
然后
srvctl start listener -n node2
srvctl start scan_listener -n node2

–检查
a) 检查crs资源状态：crsctl check crs
b) 检查集群资源情况：crsctl stat res -t

------单实例

lsnrctl stop ;
alter system switch logfile;
alter system switch logfile;
alter system checkpoint;
1.1
SQL> shutdown immediate

startup mount
create pfile=’/home/oracle/initorcl0326.ora’ from spfile;
alter database open;
