摘要:
A database is identified, wherein the database has two or more tablespaces. A local partition and a global partition for each tablespace of the two or more tablespaces is created, wherein the created two or more global partitions are included in a global storage pool. A request to move an object to a first local partition of a first tablespace of the two or more tablespaces is received. That an amount of used space of the first local partition is above a first threshold is determined. Responsive to determining that the amount of used space of the first local partition is above the first threshold, at least a portion of the object is stored in the global storage pool.
