Answer» ASM and database instances share access to disks in a disk GROUP. There can be one ASM INSTANCE and one database instance serving single database in a node. There can be one ASM instance,MULTIPLE database instances serving many database in a node. If the ASM instance fails,all the databases fails.The advantage is that this doesn't demand a Server reboot(Operating system restart). There can be clustered ASM instances that are clustered using ORACLE Clusterware.(i.e)One ASM instance on each node that are INTEGRATED using Oracle clusterware. ASM and database instances share access to disks in a disk group.
