Use DBC.DiskSpaceErrorV to determine if any database has exceeded its maximum perm space or permissible skew limits. If so, you must manually adjust the maxperm space for those databases to prevent future database updates from exceeding the maximum and experiencing out of space errors.
Some applications (such as FastLoad, MultiLoad, and restore operations) may require more temporary space during processing.
Fields in DBS Control can be set to allow applications to exceed the maxperm space as long as there is physically enough disk space available. After the operation completes, reset the fields.
