Opaque Data Normalization Methodology

      Operations involving data transfers with machines of different
data architectures, require the translation of the data structure to
local data structure representation.

      Machine-independent data structure representations are
manipulated as follows:,  In a UNIX* based ESMS environment, during
storage group or file backup or recovery operations initiated in a
distributed, hose based archive server environment, data is
transferred between MVS and UNIX systems.  The data structure
representation is different in the two environments and must be
translated before it is used by the local system.

      A machine-independent data structure has been developed to
compensate for the difference of the two environments.  The data will
be put into a structure with six parts.  The six parts that make up
the machine-independent data structure are UNIX translate program
length, UNIX translate program MVS translate program length, MVS
translate program, data length and data to be translated.

      The sender will provide a two programs one that maps the data
to UNIX data structures and one that maps the data to MVS Data
Structure.  The system operating on the data will call the
appropriate program prior to using the data.

      In this way are defined machine independent data structures for
MVS and UNIX systems.
