Storing multiple index fragments in a single dbspace

You can store multiple fragments of the same index in a single dbspace, reducing the total number of dbspaces needed for a fragmented table. You must specify a name for each fragment that you want to store in the same dbspace. Storing multiple index fragments in a single dbspace simplifies the management of dbspaces.

You can also use this feature to improve query performance over storing each fragment in a different dbspace when a dbspace is located on a faster device.
