Re: ADRDSSU protection [was:RE: Using FTP to send loadlib]

As a sysprog, I agree.

For the applprog, verify what happens when a data set is on ML1 or ML2
and a masked include is used. DSS used to skip these and still have a
zero return code. This caused the application source to be left off of
their DR tapes.

Thank you from this applications programmer for the most sensible and
reasonable answer and attitude I have yet seen.

It would be terrific if every systems programmer and storage
administrator and auditor and management were so enlightened.

Obviously some shops must be radically different. In a full SMS
shop,
applications programmers of course have no business doing volume-
level
or volume-specific operations, and to prevent override of RACF
access
restrictions ADRDSSU ADMIN authority must be tightly restricted to
those
authorized to perform DASDAdmin functions; but for us to deny
applications access to DFDSS for dataset level backup/restore
functions
on their own application datasets would be counterproductive.

We find that SMS configuration and conventions can reasonably be
used
to
handle a few backups, but are completely inadequate for many others
where the only kinds of backups that make sense are driven by
application-level events, with sets of related datasets that must be
handled as a consistent group, and/or with archival retention
requirements that don't fit within the rather simplistic SMS
management
capabilities.

As a SysProg it is part of my responsibility to see that we can
recover
the data center as a whole to a point-in-time in the event of a data
center failure. But, I do not have the time, the inclination, or
the
responsibility to determine what additional backups many different
individual application areas may need in order to recover from
mini-disasters caused by application program failures, to reprocess
old
data because of changed end-user requirements, or to meet data
archival
requirements imposed by management or law specific to that
application
area.

Given that there are of necessity backups that must be designed by
and
maintained by non-SysProg, applications people who are the ones in
the
best position to understand their archival requirements, to deny
them
ADRDSSU, effectively limiting them to sequential file backups and
awkward and inefficient file stacking on tape backups, makes little
sense.
