Subject:      Update on the problem of NOMAD2 running in CMS Release 6

Previously, I distributed mail describing a problem with file
corruption when running NOMAD2 on CMS Release 6.  Briefly, the problem
occurred during update activity and was traced to a weakness in NOMAD2
prior to version 5.0.  We installed Version 5.0 of NOMAD2 and saw no
further file corruptions during insert activity.

Since sending the mail we have experienced several more file corruptions
while running NOMAD2 V5.0 in CMS Release 6.  Evidence thus far points
to periodic corruption when NOMAD2 ABENDS or the VM Session terminates
after updating (adds, deletes or changes) has occurred and before NOMAD2
performs a database save.  MUST is currently (and vigorously ) pursuing
the problem.  We are recommending that our NOMAD2 users not migrate to
CMS Release 6 (they are currently IPLing Release 3).

The intent of this posting is to alert other VM sites to possible
problems running NOMAD2 on CMS R6.  The cause of the corruptions as
speculated in paragraph 2 is just that - speculation.  When I have more
info I will post again.
