    Unanswered: Multiple Oracle installations on same Solaris machine

    Hi

    I have Oracle 8.1.6 installied at the moment under Solaris 2.8. I now should install Oracle 9.2, but not destroy Oracle 8.1.6. (so I don't want to upgrade 8.1.6 but have 9.2 running in parallel)

    The Oracle documentation is a bit vague in this respect, when it says:
    If you have an existing Oracle installation, Oracle
    Corporation recommends that you install Oracle9i
    9.2.0.1.0 into a new Oracle home directory.

    It is not possible to have more than one Oracle
    release in the same Oracle home.
    What do they mean with "Oracle home"? I assume it's not the directory pointed to by ORACLE_HOME, but the Unix home directory. (would also be ORA_BASE_DIR)

    So is the idea to change the home-directory of 'oracle' in /etc/passwd?

    Many thanks for your advice here.

    Assuming you are following OFA
    /u01/app/oracle/product/8.1.7
    /u01/app/oracle/product/9.2.0
    what is typically have are environmental files for each version installed.
    oracle.817.env
    oracle.920.env
    where
    ORACLE_HOME=/u01/app/oracle/product/8.1.7 or
    ORACLE_HOME=/u01/app/oracle/product/9.2.0

    We have something similar. *giggles*

    Home directory of oracle: /u00/app/oracle
    ORACLE_HOME=/u00/app/oracle/product/8.1.6

    What I'm worried about is all the stuff outside .../product/8.1.6. (like admin, etc, net under /u00/app/oracle)

    Will they stay untouched? Or at least "modified accordingly" instead of simply being overwritten?

    ORACLE_HOME=/u01/app/oracle/product/9.2.0
    That definitely sounds like a good idea. Unfortunately I wasn't the one who installed 8.1.6 and it all seems a bit messy to me... The 8.1.6 installer doesn't even find what products are intalled...


    So maybe I should do the following:
    -don't change anything in /u00/app/oracle
    -create a new directory /u01/app/oracle
    -change the home-directory of the user 'oracle' to /u01/app/oracle
    -install Oracle9 normally as if it was the only DB

    Does that sound like a plan that could work? Of course I still would have problems with setting up listeners right and stuff, but...
