Hi Gurus,

Already on OAS 5.9 (FMW is 12.2.1.4) , now trying to do an inplace upgrade to latest OAS which is 6.4.

Started installing OAS 5.9 (as FMW is already 12.2.1.4 no need to install it AGAIN which was mentioned in Oracle documentation).

https://docs.oracle.com/en/middleware/bi/analytics-server/migrate-upgrade-oas/upgrading-latest-release-oracle-analytics-server.html#GUID-93B3A0DC-7546-4ABB-946E-593B3AAE444D

But at step 3 of install process after providing the "Oracle_Home" location (the same Oracle_Home in which FMW and OAS 5.9 were installed before), i get the below error.

INST-07545: Unexpected Error. The distribution oa_platform 6.4.0.0.0 contains incompatible features with the following:



Please advice how to fix this..

Thanks.

    Hi..

    Came across similar errors in online search and suggestions like "specify an empty new Oracle Home" appeared. But here as the very purpose is to "Upgrade" existing version of OAS to 6.4, obviously i MUST specify the SAME oracle home.

    Please share any inputs ..

    Thank you.

    Update: Found Doc 2764086.1 on my oracle support knowledge portal, which states that a separate FMW need to be installed (which creates a new Oracle_Home) and in this new Oracle_Home we need to install OAS 6.4.

    Note: Even though the existing FMW is the same version (12.2.1.4), a new FMW need to be installed.

    I'm coming across this same issue for OAS 7 (2023). Did creating a new Oracle_Home work for you? I'm hoping that I can rename the current Oracle_Home to something else, install FMW to create a new Oracle_Home folder, then move the domain folders from the old Oracle_Home into the new one.

    Note: Even though the existing FMW is the same version (12.2.1.4), a new FMW need to be installed.

    This is because FMW is only one piece of the equation: the OAS binaries are injected right into that FMW ORACLE_HOME, therefore you don't really have a clean FMW 12.2.1.4 anymore when you are about to install the OAS 6.4 (or 7.0 now) binaries.

    The in-place upgrade will require a new ORACLE_HOME with the new binaries, to upgrade the domain and then you can delete the old ORACLE_HOME once done. Of course this works well if you did install a clean environment with the domain being outside of the ORACLE_HOME (as the documentation always said to do).

    Don't start with renaming things, you will just kill your environment. If that's your need it will be faster to drop everything and do a clean install and restore your content than start going into renaming things.

    Hello,

    When we do the in-place upgrade and install the new home, do we use the same linux user that we used to install the former fmw home or do we need to create a new linux user for the installation of the new oracle home?

    Thanks

    I would use the same user, because it is in-place, existing folders/files will be reused. By using the same user you avoid any permission issue that you will probably have with a different OS account.

    It's anyway meant to be a technical account used for OAS, it does make sense to use it for all your OAS products (which also cover the in-place upgrades etc.).

    I concur with @Gianni Ceresa

    But if its mandatory, you can take a backup of the existing DOMAIN_HOME and use

    chown -R newuser:newgroup $DOMAIN_HOME

    then perform the in place upgrade with the new user using the documentation.

    But a caution, this may need careful evaluation to avoid any complication with the scaled out approaches and high availability approaches

    Thanks,
