Although there are basically three types of DMSII database reorganizations (record format conversion, file format conversions, and garbage collection reorganizations), the types of reorganizations are not as important as whether the reorganization changes record layouts or record locations, as follows:

  • DMSII record format conversions change record layouts. When a data set is affected by a record format conversion, parallel changes must be applied to the Client database. See DMSII Changes to Record Layouts.
  • DMSII file format conversions and garbage collection reorganizations change record locations. Only certain data sets require recloning in this case. See DMSII Changes to Record Locations.

    Note: Filler substitutions are handled the same as a record format reorganization. In a filler substitution, there is a change to the item count.
