During each reorganization, SAPDBA checks whether all reorganized objects can be recovered with their data in the appropriate tablespaces. Besides the size of initial and next, the number of extents expected is also taken into account (according to minextents and the amount of data to be imported). This corresponds to the default of the option Check space: for all extents.

In certain exceptional cases (particularly when the option Compress Extents: no and/or Reduce object size: no is set), the memory space check may be too restrictive. SAPDBA states that there is not enough freespace, even though there is.

In such cases, you can set the option Check space: only first minextents. This means that only the initial extent or the extents according to minextents are included in the storage space check. Other nextextents are not taken into consideration in the space check.
