PM04687: PROVIDE NEW FUNCTION COPY FEATURE AND COMPRESS FEATURE

APAR status

• Closed as new function.

Error description

• - Provide a COPY function
  The COPY function creates a copy of the database
    while it is being updated. It uses the shadow datasets to copy
    the database to. The shadow datasets are kept. The database on
    the shadow dataset is consistent. There is no need to use a
    fuzzy read (GON/GOT PSB) to process the database.
    HALDB Toolkit can be used to process HALDB's without having
    them registered.
  - Compress the unload file when using HPLOAD for reload.
    In response to FITS # MR1130092925.
    The unload file contains un-compressed segments when
    secondary indexes must be created.  This increases the size
    of the unload file. The process has been changed to expand
    the segment at the reload process when the segment is an
    index source segment.
