1. The answer to your question is: it depends! If you use the VALIDATE
keyword on the DUMP (it's the default), indexed VSAM files are reorganized
during RESTORE processing. The manual is "very clear" <g> : "3. When a data
set is restored, the free space in the control areas and control intervals
are reset to the values in the catalog entry." (Stg Admin Ref: "VALIDATE"
Note 3).
2. DSS COPY does NOT reorganize the files in most cases (IMHO). This is
especially true when "fast replication methods" (FastCopy/Snapshot) are
used. IDCAMS is only used if some target attributes are different from the
source.
