I installed V8.2 64bit under Solaris alongside V8.2 32bit in order to
overcome a 3Gb memory limit for proc mddb. The elapsed time was reduced
considerably but memory utilisation shot up to the point where we ran out of
swap space on one occasion. The problem appeared to be that memory
utilisation was increased across the board compared with V8.2 32bit with no
significant savings in CPU. We have 6x750MHz with 12 Gb RAM and SI
recommended increasing to 16 Gb. Unfortunately we could not reach concensus
between my clients, SAS, Sun and my Sys Admins so we put everything on hold.
My concern is that Rel 9 is based on the same 64bit structure. Once we get a
delivery date for Rel 9 here in Canada, I will revisit the processes and
make another assessment.

Hello big file crunchers,
We currently run SAS 8.2, 32 bit on our AIX box. We are thinking about
switching to 64 bit with hopes of increasing performance. Does anyone have
experience with making this switch? What have you noticed as advantages and
As always thanks to the real experts.
