12c 如何将Standard ASM转化为Flex ASM

什么是Flex ASM?

我们知道在12c之前的版本里，ASM实例需要在每一个节点运行，而ASM 的客户端(Database，ACFS，ADVM)只可以访问本地的ASM 实例。如果使用了Oracle Flex ASM，情况就不一样了，ASM的客户端就可以通过ASM网络访问远程的ASM实例。如果一个运行ASM实例的节点宕掉，Oracle集群会在另外一个节点上启动一个新的ASM实例以此维持它的节点基数(Cardinality)。 同样，如果一个12c数据库实例连接了某一个ASM 实例，而这个ASM 实例crash掉或者实例运行出错，这个数据库的实例会尝试重新连接在另一个节点的一个已经存在的ASM实例，这就是 Oracle Flex ASM。


Flex Cluster和Flex ASM的区别

Flex Cluster需要Flex ASM的支持

Flex ASM可以在StandardCluster和Flex Cluster运行


如何控制ASM实例的个数
 

[orgrid@ohs1 ~]$ srvctl modify asm -count 2
[orgrid@ohs1 ~]$ srvctl config asm
ASM home: <CRS home>
Password file: +SYSTEMDG/orapwASM
ASM listener: LISTENER
ASM instance count: 2
Cluster ASM listener: ASMNET1LSNR_ASM
[orgrid@ohs1 ~]$
[orgrid@ohs1 ~]$ srvctl modify asm -count 1
PRCA-1123 : The specified ASM cardinality 1 is less than the minimum cardinality of 2.
注意：ASM实例至少的有2个实例，这样不至于单点故障


Flex ASM和Standard ASM的转化

我们可以把Standard ASM转化为Flex ASM，但这个转化是不可逆的。这样做的目的可能是为了推广这个特性，这个特性确实不错


如果没有使用Flex ASM，不设置SID会出现连接到空实例，但在Flex ASM情况下，会随机选择一个

[orgrid@ohs1 ~]$ asmca -silent -convertToFlexASM -asmNetworks eth1/172.16.0.0 -asmListenerPort 10010
 

To complete ASM conversion, run the following script as privileged user in local node.
