Oracle FLEX ASM: The number of ASM instances which will be running in the cluster based on cardinality defined during the cluster configuration.
Flex Cluster need to be enabled for flex ASM.
The default cardinality is 3, can be changed with srvctl modify asm commands
Clients can connect to remote ASM instance either shared network or separate dedicated asm network.
Useful commands:
srvctl status asm -detail
run at asmcmd command prompt:
showclsutermode
showclusterstate
Oracle Flex Cluster:
Oracle Flex Cluster is a type of cluster with Hub and leaf nodes. Hub nodes do have direct access to storage and its files (OCR, Voting disks, disk group files etc.)
.leaf nodes do not have direct access to shared storages. all leaf nodes communicatoin go via hub nodes. Flex Cluster need Flex ASM configured prior.
Useful Commands:
crsctl get node role config
crsctl get node role config -all
olsnodes -n -s -a
crsctl get cluster mode status
