    Multiple DB2 versions on AIX

    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.

              ..
