A volume is a logical grouping of physical storage 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 disks used should have identical performance parameters (specifically access speeds) to ensure an even filling of the volumes.

If database management tools are used, a volume is addressed via a directory path.

The database system differentiates between data volumes and log volumes.

Every database instance has one or more log volumes and data volumes. You configure the maximum numbers of data and log volumes that are possible when installing the database instance.

If necessary, you can add data or log volumes to a database instance while the database is running. Directory paths for data and log volumes can be changed.
