Is it possible to have v8.2 32-bit instance co-existing with v9.1
installation on UNIX environment. I see that it is not possible in
Windows from the DB2 v9.1 product manuals.

Yes. Just make sure to create separate instance owners.

It is possible on unix (and always has been). It is *now* possible on
Windows as of v9 (but only back as far as v8 - v9 cannot coexist with v7).

Yes, it is possible to have V8.2 32-bit instance with V9.1 64-bit
instances on Linux and UNIX except on Linux on IPF... now on windows
you can have V8.2 and V9.1 32-bit instances coexisting but you cannot
install DB2 64-bit product on windows if you have V8.2 32-bit
installed.

Hope this clarifies,

Amyris.

It's possible to have v7 & v8 or v8 & v9 intances on the same box (maybe
even v7, v8 & v9? Haven't tested). Just remember to do db2rmln after
installing (and after installing fixpaks). /etc/inittab should also have
only one db2fmcd entry. If you're running clients on the same box,
LIBPATHs etc will have to be adjusted.

Supported? Don't think so.

Supported? Definitely. Well documented, too.

You still need to have an instance for each, and, of course, they can't be
the same name. That helps keep the LIBPATHs, etc., separate.
