Re: Library Authority

   Such a response ignores the true potential for stress that might be 
involved.  The noted processing may be unacceptable to businesses for DR 
with large files, since doing so could add several tens of hours for 
access path recovery time.  Without proper planning, applications may be 
unavailable for days while critical activity competes with rebuilds for 
CPU time, or while rebuilds are given dedicated time thus preventing 
activation of other processing that is critical to the business.  While 
it may be workable for your situation, that does not make it generally 
applicable to others.  Many will never even test DR to find out that 
they will be SOL when the time comes for a real DR, so implying it is 
acceptable without emphasizing the potential caveat will leave them 
disgusted with the OS and possibly with the /advice/ they were given.

   The IBM i Operating System 6.1 offers some new techniques which 
enable spanning libraries without access path rebuilds, but only with 
explicit modifications to the DR processing.
