ASM instance has no data dictionary. Disks can be dynamically added to any diskgroup. When combined with OMF increases manageability.
Use of ASM diskgroup is very simple create tablespace. Enterprise Manager can also be used for administering diskgroups. Wait until the disks appear on the Create Asm oracle 10g Group page.
If you are working with newly stamped disks, they look like the following screenshot: If they have been previously used for ASM, they look like this: Therefore, it does make asm oracle 10g for them to have their own distribution. As of this asm oracle 10g, Oracle is still contemplating whether to make its own Linux distribution OR to buy it.

Configuration of ASM high redundancy provides a greater degree of protection.
Automatic Storage Management
With external redundancy, ASM does not provide any redundancy for the disk group. In external redundancy, the underlying disks in the disk group must provide redundancy for asm oracle 10g, using a RAID storage array.
The redundancy level or type is specified at the time of creating the disk groups. What is Automated Storage Management?

OSMB opens and creates disks in a diskgroup. RBAL provides the functionality of moving data between disks in a diskgroup.
Implementation and usage[ edit ] Automatic Storage Management ASM simplifies administration of Oracle-related files by allowing the administrator to reference disk groups rather than asm oracle 10g disks and files which ASM manages.
