A volume is a logical group of physical memory units (disks). A volume can be a part of a physical disk, a complete physical disk, or a completely structured storage system consisting of several storage units.

The database system differentiates between data volumes and log volumes. The number of data volumes and log volumes that you can define for a database instance depends on the general database parameters MAXDATAVOLUMES and MAXLOGVOLUMES. When you create a new database instance, you need to configure at least one data volume and one log volume. If required, you can add further volumes during database operation, until you reach the values specified in the database parameters MAXDATAVOLUMES or MAXLOGVOLUMES.
