We have several machines currently running the DB2 V7 Run-time Client
that we would like to actually be running the App Dev Client. To
'upgrade' (within the same version) this client software can we simply
install the App Dev Client on 'top of' the Run-time Client? Will the
install routine uninstall the Run-time Client under the covers during
the install of the App Dev Client?

Also, is this type of 'upgrade' possible/supported during a
Version-to-Version upgrade, such as when migrating from V7 to V8?

Thanks.

You can install the Appl Dev Client with the Run-time Client, insure
they are at the same release and fixpack level... Also if you plan on
connecting a v7 client to a v8 server, then the clients must be at
minimun v7 fixpack 8. You can't connect a v8 client to a v7 server (If
you happen to expect major problems).

It is not a good thing to connect with a v7 client to v8 server. I
crashed the server via ODBC and V7 twice, and once through the CLP.

To do it in the CLP just type in "SET SCHEMA CURRENT USER" and the
server itself crashes.

You can't connect a v8 client to a v7 server (If
you happen to expect major problems).

Can you be more specific with this statement doug?

We have been testing the DB2 v8.2 windows Admin Client with various 3rd
party reporting tools and with native sql queries against a few
different DB2 v7.2 aix servers. We are preparing to roll this out to
our user machines. We have had absolutely no issues so far, but you're
comments make me nervous.

Pleease elaborate if possible.

Thank you,

We have db2 8.2 clients connecting to 7.2 databases all the time
without any problems.

I am not sure where those errors are coming from, but I don't think
they are related to the client version, but to something wrong on the
server itself.

The only annoyance of the 8.2 admin client is the health center status
beacon, which writes worthless messages to the db2diag.log

To disable it (tools -> tools settings -> health center status beacon
-> uncheck everything).

It may work for your limited range of SQL statements, but it does not work
for everything. IBM does not support clients connecting to back-level
servers, even when 7.2 supported.

This is from v8's Infocenter at ibm.com. So looks like IBM supports it
at least

To access a DB2 Universal Database Version 7 server on a Linux, UNIX,
or Windows operating system from a DB2 Version 8 client, you must

* Have DB2 Version 7 FixPak 8 or later installed on your server;
and
* Have run the db2updv7 command.

I'd always tought that support was:
1 level up, 2 levels down.
A V8.2 client should be able to connect up to V??? and down to V7.1.0 or
V7.2 server.
A V7.2 + client should be able to connect to A V8.1. server (I don't think
a V8.2+).

If one has a V8.2 server, I'd think that you'd need a V8.1 or V8.2 client.
But then you'd be ready for V?? coming out sometime in this near future.

Thank you for all of the replies on this thread. But I am still
looking for the answer to my original question (which is repeated
below).
Can anyone help me on this please?
================================================== ==================

We have several machines currently running the DB2 V7 Run-time Client
that we would like to actually be running the App Dev Client. To
'upgrade' (within the same version) this client software can we simply
install the App Dev Client on 'top of' the Run-time Client? Will the

Also, is this type of 'upgrade' possible/supported during a

Thanks.

Which version of the app dev client? If it's the same or higher level, you
can just install app dev client over top of the runtime client, and you'll
end up with both. The disadvantage is that, if you're on Windows, you'll
need both fixpacks in order to apply a new level of the code. (Unix/Linux
has one fixpack for all products, so you'll continue using the same fixpack
to upgrade both at the same time.)

However, since I think you're on Windows, you should also be able to go into
the add-remove programs to uninstall the runtime client after having
installed the application development client. Your instance(s) should
remain intact.

No, it won't uninstall the runtime client under the covers.

Sure. That should work just fine.
