The virtual process size (or address space) for the Dgraph is the total amount of virtual memory allocated by the operating system to the MDEX Engine process at any point in time. This includes the Dgraph code, the MDEX Engine data as represented on disk, the Dgraph cache and any temporary work space.

For more information, see the Oracle Commerce MDEX Engine Performance Tuning Guide.
