rac修改instance_name

oracle版本:11.2.0.4

需求:
RAC两个节点RAC1和RAC2，分别对应实例为racdb1和racdb2，将实例名
修改为racdb_1,racdb_2




--1.停止实例名


[oracle@rac2 ~]$ srvctl status database -d racdb
Instance racdb1 is  not running on node rac1
Instance racdb2 is  not  running on node rac2


[oracle@rac1~]$ srvctl stop instance -d racdb -i  racdb1
[oracle@rac1 ~]$ srvctl stop instance -d racdb -i  racdb2


--2.杀死oracle进程


在两个节点的系统检查oracle进程是否被正常枪毙 ps aux | grep ora




--3.删除再添加


[oracle@rac1 ~]$ srvctl status database -d racdb
Instance racdb1 is  not running on node rac1
Instance racdb2 is  not  running on node rac2


--删除
srvctl remove instance -d racdb   -i racdb1
srvctl remove instance -d racdb   -i racdb2


--添加
srvctl add instance -d racdb   -i racdb_1  -n rac1
srvctl add instance -d racdb   -i racdb_2  -n rac2






--4.启动2个实例


srvctl start instance -d racdb -i  racdb_1
srvctl start instance -d racdb -i  racdb_2


[oracle@rac2 ~]$ srvctl status database -d racdb
Instance racdb_1 is running on node rac1
Instance racdb_2 is running on node rac2








SQL> select instance_number,instance_name from gv$instance;


INSTANCE_NUMBER INSTANCE_NAME
--------------- ----------------
          2 racdb_2
          1 racdb_1


SQL> show parameter instance_name;


NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
instance_name                 string     racdb_1






SQL> show parameter instance_name;


NAME                     TYPE     VALUE
------------------------------------ ----------- ------------------------------
instance_name                 string     racdb_2






--5.修改pfile(两个节点)
