Functional Overview

The ADAULD utility unloads an Adabas file. Adabas files are unloaded to:

The sequence in which the records are unloaded may be

physical the order in which they are physically positioned within Data Storage.
logical a sequence controlled by the values of a user-specified descriptor.
ISN ascending ISN sequence.

Selection criteria (SELCRIT/SELVAL) are optionally used to indicate a subset of records to be unloaded:

The unloaded record output is in compressed format. The output records have the same format as the records produced by the ADACMP utility.

When using the MODE=SHORT option, descriptor entries (which are required to create the normal index and upper index for the file) are omitted during the unload process. This reduces the time required for unloading. Note, however, that output created using MODE=SHORT has a different FDT from the same file unloaded without MODE=SHORT, since all descriptor information is removed.

Notes:

  1. An interrupted ADAULD UNLOAD FILE run must be reexecuted from the beginning.
  2. Logically deleted fields will appear in data unloaded by the ADAULD utility.
