Disk, memory, and process management
Manage disk spaceYou can use several utilities and tools to manage disk spaces and the data that the database server controls.
Drop a storage spaceUse onspaces or ON-Monitor to drop a dbspace, temporary dbspace, blobspace, sbspace, temporary sbspace, or extspace.
Back up after dropping a storage space

Back up after dropping a storage space

If you create a storage space with the same name as the deleted storage space, perform another level-0 backup to ensure that future restores do not confuse the new storage space with the old one. For more information, see the HCL OneDB™ Backup and Restore Guide.

Important: After you drop a dbspace, blobspace, or sbspace, the newly freed chunks are available for reassignment to other dbspaces, blobspaces, or sbspaces. However, before you reassign the newly freed chunks, you must perform a level-0 backup of the root dbspace and the modified storage space. If you do not perform this backup, and you subsequently must perform a restore, the restore might fail because the backup reserved pages are not up-to-date.
