| Hi Norbert,
I am so glad to find your note in the Rdb_60 conference. I am
about to do exactly the same thing to a telecom customer in Hong Kong.
They are currently running on two VAX-7000. A new Alpha 8400 is going
to be added as the DB server. The current VAX will access the DB
through Rdb Remote Access.
I would be very grateful if you could share your experience in such
an exercise. Any particular watch-outs ?
I assume that the Rdb Buffers are on the Alpha side therefore, if
an application on Machine A read a record into buffer, that will make
it available to a remote access from Machine B as well. Is this true ?
Do you see significant increase in network traffice afterwards ?
Thanks very much for your help,
Eddie

Tuning Alphas can be fairly different than tuning VAX systems. SYSGEN
parameters and AUTHORIZE quotas are rarely directly transportable between
the two architectures. Don't forget to tune your Alpha for its environment
and not tune it just like the VAX.

The database buffers are on the server. If you have one Alpha as the
database server *and* you're using global buffers or record caching, then
data would be share-able between all users on that server node. If your
database is using only local buffers, then there will be no sharing of data
in memory.
