Effect of configuration on I/O activityThe configuration of your database server affects I/O activity.
Chunk and dbspace configurationThe number of disks that you use and the configuration of your chunks, dbspaces, and blobspaces affect the performance of your database server. You can improve performance by planning disk use and the configuration of chunks, dbspaces, and blobspaces.
Placing system catalog tables with database tablesWhen a disk that contains the system catalog for a particular database fails, the entire database remains inaccessible until the system catalog is restored. Because of this potential inaccessibility, do not cluster the system catalog tables for all databases in a single dbspace. Instead place the system catalog tables with the database tables that they describe.

Placing system catalog tables with database tables

When a disk that contains the system catalog for a particular database fails, the entire database remains inaccessible until the system catalog is restored. Because of this potential inaccessibility, do not cluster the system catalog tables for all databases in a single dbspace. Instead place the system catalog tables with the database tables that they describe.
