测试 19c  asm flex 的 功能:




在节点1上面执行 srvctl stop asm -node test-rac19c-01 -stopoption abort -force 报错


因为 ora.asm_listener.type 是asm监听的主节点,节点1为主节点,主节点无法关闭

[grid@test-rac19c-01 ~]$ srvctl stop asm -node test-rac19c-01 -stopoption abort -force 
PRCR-1214 : failed to stop resource group ora.asmgroup
PRCR-1214 : failed to stop resource group ora.asmgroup
CRS-2670: Unable to start/relocate 'ora.asm_listener.type' because 'ora.asm' has a stop-time 'hard' dependency on it
CRS-5027: The ASM instance on node "test-rac19c-01" cannot be stopped because it is currently being used by Cluster Ready Services.
CRS-0222: Resource 'RGI: ora.asmgroup 1 1' has dependency error.
[grid@test-rac19c-01 ~]$ 
[grid@test-rac19c-01 ~]$ 


然后在节点2上执行:正常关闭


[grid@test-rac19c-02 ~]$ srvctl stop asm -node test-rac19c-02 -stopoption abort -force 
[grid@test-rac19c-02 ~]$ 



然后 查看看集群的状态:


节点1:

查看节点2的pmon 进程:发现数据库正常服务,但是asm进程没有了,这就是 flex asm 的功能,增加了一定的伸缩性与容错性

[grid@test-rac19c-02 ~]$ 
[grid@test-rac19c-02 ~]$ ps -ef |grep pmon 
oracle    15747      1  0 17:09 ?        00:00:00 ora_pmon_prod19c2
