Hi Sybase Gurus,

I need to install EAStudio & EAServer for my customer in a 3-tier
configuration. Could you verify that these are the proper components
for the 3 machines? I have read over the documentation but I did not
see how to do the setup in a 3-tier environment. We will be building
a web-application that will use Jaguar for the DB access. There will
be no DataWindow, PowerBuilder, or CICS access. Java will be used
for data access.
Note also that we want to use Adaptive Server Enterprise running on
Solaris as the database instead of ASAnywhere. Problem?

WEB-SERVER :
NT with IIS
PowerDynamo
Sybase Central
Jaguar Client
Jaguar Manager
Sun JDK

TRANSACTION-SERVER:
NT
Jaguar Server
PowerJ
JConnect
SurfSide Demo
Sun JDK

DB-SERVER:
Sun Solaris OS
Adaptive Server Enterprise
Sybase Central
SQL Modeller
JConnect

As usual, thanks for your expert opinion and continued support!
Roland Cuellar

Roland -

You might want to mention what kinds of boxes you are running on. This
will help in placement of the different tools/servers. Also do you plan
to do development on the servers or from client machines? You list seems
to have some client software on the servers.

Mark,

Thanks for responding. The web-server and transaction server are
Compaq 1850R's dual 550's 256 meg ram and 2 9.1GB running
NT.
The back-end database server is a big Solaris machine ... I'm not
sure of the exact model but also a very capable machine.

We will probably want to do website/dynamo coding on the web-server.
We will probably want to do Jaguar coding on the transaction server.
Database builds, admin, etc on the backend Solaris machine.

So we will probably work directly on the servers themselves most of
the time. What would that configuration need to look like?

And since you mentioned it, what would a configuration look like
if we wanted to develop from client machines? Would we need
any additional software?

In your opinion, what is the best solution? I anticipate 3 or 4
developers total. Some working on web pages and dynamo.
Others working at the Jaguar level. And someone doing
DB admin etc.

Once again, thanks for your help.

Roland Cuellar

Roland -

I would probably have developers working on their own machines and use
the servers as servers. This will take some load off them and not affect
the servers if a client app GPFs or takes up more memory then it should.
With that said - ideally developers might want to work on their own
machines - client and server - and publish to the servers. But this takes
a bigger client machine and may not be worth the effort.

I am not sure I know what to recommend. If you have PD doing a lot of
calls to Jaguar then you might want them on the same machine. But you
really need to understand the load and use of the servers. There are a
lot of factors that go into these decisions. Load, do you need fail-over,
is the web site only PD/Jag pages/servlets or will there be an IIS site?
Etc...

I think it would be heard for someone to detail a configuration w/o
knowing all the factors. Maybe why people did not respond <g> What I
would suggest is trying out the configuration you had and see what kind
of performance you get with the load you expect. Not the answer you
wanted to hear, but...

Just my 2 cents,
Mark
