Thanks Michael.  I will address the subject about the weekly reorgs with our 
gurus (hard headed).  Hopefully they will come around.

multi-system sysplex.

You should re-consider your policy to reorganize your HSM CDS's weekly.
The article at http://www.mainstar.com/pdf/000-0112_HSM-CDS-Tng.PDF does
a good job of describing the problem you are creating by reorganizing
once a week.

You also have the option to split the MCDS into 2, 3, or 4 MCDS data
sets. Check

Subject: Re: HSM : CHANGING TO VSAM EXTENDED

It used to be a requirement that to go EA with the CDS' required that
you 
go RLS first. We followed that route and actually found some
significant 
improvement in HSM processing times due to the RLS conversion, however,
I 
believe that now you can go EA without having to first convert to RLS 
processing.
