某些时候我们需要到客户现场去做保障，偶尔会需要停下数据库集群，然后停机。通常我们会采取比较稳妥的方式，而不是野蛮暴力的方式。
野蛮的方式
# /u01/app/oracle/product/10.2.0/db_1/bin/crsctl stop crs
日志
Shutting down instance (abort)
License high water mark = 5
Instance terminated by USER,pid = 9068
2.温柔的方式
[root@node1 root]# su - oracle
[oracle@node1 ~]$ crs_stat -t -v
[oracle@node1 ~]$ srvctl config database
racdb
[oracle@node1 ~]$ srvctl stop database -d racdb
[oracle@node1 ~]$ srvctl stop asm -n node1
[oracle@node1 ~]$ srvctl stop asm -n node2
[oracle@node1 ~]$ srvctl stop nodeapps -n node1
[oracle@node1 ~]$ srvctl stop nodeapps -n node2
[root@node1 root]# /u01/app/oracle/product/10.2.0/db_1/bin/crsctl stop crs

3.启动方法
[root@node1 ~]# su - oracle

/u01/app/oracle/product/10.2.0/db_1/bin/crsctl
[oracle@node1 ~]$ exit
logout

最近有点忙，有些懈怠了，博客更新的也不及时了。还是要继续坚持才可以，少找借口，自我批评一下。
