The percentage of free space to remain on a cylinder after a loading operation completes. This specification does not immediately affect existing cylinders, but the new attribute value controls any new allocation of data blocks using this revised free space percentage.


For Object File System tables, FREESPACE has a default setting that you cannot change.

For additional information, see FREESPACE PERCENT with CREATE TABLE (Table Options Clause).

The FREESPACE setting you specify affects the following operations:
  • FastLoad data loads
  • MultiLoad data loads into unpopulated tables
  • System reconfiguration
  • MiniCylPack

    If not enough cylinders are available and storage space is limited, MiniCylPack may not be able to honor the specified FREESPACE value.

  • ALTER TABLE request that adds fallback protection to a table
  • CREATE INDEX request that defines or redefines a secondary index on a populated table
  • Creation of a fallback table during an INSERT ... SELECT operation into an empty table that is defined with fallback.
  • Creation of a secondary index during an INSERT ... SELECT operation into an empty table that is defined with a secondary index.
