DB2Connect EE to connect to DB2 for z/OS

[Jerry Orr]

We are trying to determine the easiest (and cheapest) way to get
connections for about 50 Win2K workstations on our LAN to DB2 on a
z/OS server.

We could install DB2 Connect Personal Edition on every workstation,
but that would require purchasing a license for each workstation (or,
more likely, a site license). We would like to avoid that option.

I've heard mixed accounts of what DB2 Connect ENTERPRISE Edition can
do. One source says that we can just install EE on a server on our
LAN, and then everyone has access to its connections. This would be
ideal, as it would require only 1 license. However, I've also seen
sources that imply that you still need some sort of client installed
on every workstation. Is that client free? Or does it require licenses
as well? Or is it just referring to the Personal Edition?

If you still need the Personal Edition installed on every workstation,
then I'm not entirely sure what the benefit of the Enterprise Edition
is.

Any insight into this situation would be greatly appreciated!

No sure for DB2 Connect, but I know that similar drivers such as StarSQL are
priced by concurrent connections (you might want to ask StarQuest or other
ODBC vendors what they would charge and then compare with IBM) . I believe
that DB2 Connect still has to be installed on each workstation where the
application resides.

With enterprise, you can install the DB2 run time client on every
workstation (smaller than personal edition). Or, you can use a Type 4
JCC driver. Either way, you have to license client connections to z/OS
with a license as described in the announce letter:

DB2 Connect Application Server Edition: DB2 Connect Application Server
Edition product is identical to the DB2 Connect Enterprise Server in its
technology. Just like the DB2 Connect Enterprise Edition it is designed
for large scale demanding environments. However, its licensing terms and
conditions are meant to address specific needs of multitier
client-server applications as well as applications that utilize Web
technologies. DB2 Connect Application Server Edition license charges are
based on the size of the number of processors available to the
application servers where the application is running. License charges
are not affected by the number of users of the application, size of the
DB2 Connect server itself, or the size of the mainframe database server.

DB2 Connect Unlimited Edition: DB2 Connect Unlimited Edition product is
ideal for organizations with extensive usage of DB2 Connect, especially
where multiple applications are involved. This product provides program
code of the DB2 Connect Personal Edition as well as program code
identical to the DB2 Connect Application Server Edition for unlimited
deployment throughout an organization. DB2 Connect Unlimited Edition
license fees are based on the size of the mainframe database server
(measured in MSUs) and are not affected by either the number of users
nor the number of processors available to the application servers. This
makes DB2 Connect Unlimited Edition an ideal choice for organizations
where multiple applications are utilizing DB2 Connect or organizations
with a mix of two-tier, multitier client-server, Web-based applications.

We found the easiest solution to be a DB2 Connect EE on a server, with a DB2
runtime on each client. It's a lot easier to maintain when the W2K - z/OS
connectivity is well controlled, although, of course, it does add a single
point of failure.

Blair has addressed the license costs.
