| Since there hasn't been any response to this request I'd like to
re-open the question. Does anyone have any comments, good or bad, about
the combination of Natural & Rdb? Also, are there any links, or
export/import capabilities, between the PREDICT dictionary environment
and CDD/Plus?

| More importantly...
NATURAL with ADABAS on IBM and on VAX uses a single process to control
ALL database operations. This is fine when you're running 12 partitions
on a 3081, one of which can be dedicated to database serving.
This is a right pain with SMP and Clusters because the database server
can only run on on CPU board and only on one node in a cluster.
Combine this with NATURAL's tendency to use packed decimal and all of
a sudden that two or three node 6x20 cluster you proposed is looking
very dogy indeed. (9000 here we come).
The big question is: How does NATURAL use VAX Rdb/VMS? Does it still
implement this single server approach? If so, how the heck are you
going to cope with 500+ concurrent users on a VAX based NATURAL system
REGARDLESS of which database it's using?

| -> ADABAS single process:
ADABAS uses one process per Database, so you can use multiple databases
-> NATURAL V2, which is able to work with RDB, has at least 50% bader
Performance than NATURAL V1.
-> 500+ users
NATURAL uses RDB via DSRI-calls. Each User has his own NATURAL-Process.
So NATURAl with RDB has no single server architecture.
NATURAL cannot use ACMS. NATURAL will use approximatly 1 MB Memory for
each user.
I was a SoftwareAG employee for 3 years, so feel free to ask me.
