Disk Groups
Go Up to Supported Objects
When connected to an Oracle datasource with an ASM instance, the Navigator’s Instance node shows ASM and ASM > Disk Groups subnodes. DBArtisan lets you connect to the ASM instance and provides basic object management for disk groups.
DBArtisan lets you use the default datasource connection or a dedicated connection to the ASM instance. When using the default datasource connection, you can open a Disk Group Editor but you can only view limited properties of the disk group. With a dedicated connection to the ASM instance, you can create and edit disk groups and make use of the disk group-specific object actions: Check Disk Group, Mount Disk Group, Rebalance Disk Group, and Undrop Disk. After connecting to the datasource, you are prompted to choose between the default datasource connection and a dedicated ASM instance connection on the first object action against a disk group. The connection type persists and you can also explicitly change the connection type using the Manage ASM Connection and Disconnect ASM Connection actions.
- Note: The ASM and Disk Groups nodes are only visible if the datasource instance has an ASM instance.

Connection details
When registering an Oracle datasource:
- As of Oracle 11gR1, you can specify the SYSASM privilege for the datasource connection. This provides full ASM administrative privilege for this connection.
- Using the SYSDBA privilege, you can register the ASM instance directly using the Datasource Registration Wizard.
