Oracle Product集群因OS需要打patch需要单独关闭节点进行维护，机器为个人测试Oracle 11g R2测试集群

操作步骤

--确认集群的db_unique_name,本初的db_unique_name为orcl

SQL> show parameter name

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

cell_offloadgroup_name               string

db_file_name_convert                 string

db_name                              string      orcl

db_unique_name                       string      orcl

global_names                         boolean     FALSE

instance_name                        string      orcl2

lock_name_space                      string

log_file_name_convert                string

processor_group_name                 string

service_names                        string      orcl

--确认集群的instance_name

SQL> select instance_name,status from gv$instance;

INSTANCE_NAME    STATUS

---------------- ------------

orcl2            OPEN

orcl1            OPEN

#本处的两个实例名为orcl1 和 orcl2

--关闭node1监听，确保应用无法通过监听连接数据库

[grid@oranode1 ~]$ srvctl stop listener -n oranode1

#使用crs_stat -t -v命令或者使用srvctl status listener命令检查监听运行情况

[grid@oranode1 ~]$ srvctl status listener -n oranode1

Listener LISTENER is enabled on node(s): oranode1

Listener LISTENER is not running on node(s): oranode1

[grid@oranode2 ~]$ srvctl status listener -n oranode2

Listener LISTENER is enabled on node(s): oranode2

Listener LISTENER is running on node(s): oranode2

#确保关闭前实例上没有session在执行，如果有停机窗口的话建议杀一次local=no的会话

[oracle@oranode1 ~]$ ps -ef |grep -i local=no |wc -l

1

[oracle@oranode1 ~]$ ps -ef |grep -i local=no |cut -c 10-15|xargs kill -9

kill 7803: No such process

--关闭集群节点一上的数据库实例

[grid@oranode1 ~]$ srvctl stop instance -o immediate -d orcl -i orcl1

[oracle@oranode1 ~]$ sqlplus / as sysdba
