I have a requirement to setup DB2 on a 4 node cluster using Veritas
(with the DB2 failover agent).

I may have a requirement to have more than one database running on the
cluster at a different DB2 version (8.1, 8.2) or Fixpak release (8.1
FP5 and 8.1 FP6 and 8.1 FP7 - for example).

Is this possible? I can't see a way to change the default installation
directory for DB2.

Any help much appreciated.

Regards,
Nic

This is no problem. Use the alternate fixpaks. The original code (or latest
code) stays were it is, but the new alternate fixpak code will be installed
on its own directory. Then you create or upgrade the instance for whatever
version you want by running the instance command from the correct directory.

Thanks. How many alternate FixPak installations can you have per node?
I may have to try to accomodate 2-3 - is this possible?

If 8.1 binaries get installed into default location (db2_08_01), can I
have a FP5, FP6 and FP7 directory structure for example pointing to the
8.1 code?

Thanks.

I don't know if there is a limit. I have seen at least 5 different versions
on the same node.

When you install the alternate fixpak, it will automatically install in the
correct (different) directory name. You don't need to do anything to name
the directory path. For example, if you install Alternate FP7, it will
installed at /opt/IBM/db2/V8.FP7

These directories are for Linux. I think AIX installs DB2 in a different
directory than /opt IIRC.

When you update the instance (or create a new instance) with the new fixpak
level, just go to the correct directory level to run db2iupdt
(/opt/IBM/db2/V8.FP7/instance). That will point the instance to the correct
fixpak.

..

Many thanks for the reply - very useful!
