Hello,

I have an environment that contains V8 (FP 11) and V7 (FP13) Linux
servers.

One of our applications reads data from V8 servers and writes
summarized data into V7 servers that can´t be easily migrated for
several reasons.

Because I have to connect to both V8 and V7, the runtime client
installed on the application server is V7. V8 runtime connecting to a
V7 server has some know limitations.

Question is: Can I install both runtime clients on a single box?
Perhaps create an instance for each client and configure the
application to use this or that version ?

Thanks in advance,

Yes. DB2 for Unix and Linux supports multiple versions coexisting. As you
surmised, each must have its own instance. As far as I'm aware, you can
only use one instance environment at a time for a given process.

"Version" means the first number: v7 and v8 coexist. Two different copies
of v8, being the same version, do not coexist (unless you have the
alternate fixpak - that's not available on all platforms, and only for
ESE).

Viper allows multiple copies of DB2 to coexist on the same box. Each one
still needs its own instance(s) to do anything useful, though.

Thanks Darin,

I will install both and see what happens.
