Question on upgrading Oracle 12c client to Oracle 19c Client.

  • 1.  Question on upgrading Oracle 12c client to Oracle 19c Client.

    We have a new Oracle 19c server.   We also have an existing Enforce server that is running 12.2.   We want to point our Enforce server to to the new Oracle 19c server.

    1) Do we need to upgrade our Oracle 12c client to Oracle 19c client to connect Enforce to the the new Oracle Server?
    2) If yes, does anyone have instructions on how to upgrade the Oracle client on Enforce to 19c?   When I try to upgrade it, I get the error "INS-32103] Specified Oracle Home User does not match with existing home user.

    I am trying to install the new Oracle 19c client over the existing 12.2.x oracle folder.

    Should I instead install the new Oracle 19c client on its own oracle D:\oracle\product\19.3.0.0\client_1 folder?   If yes, do I need to do anything else like change the environment variables to to point to the new 19.3.0.0 folder?

    *** If we cannot upgrade the Oracle 19c client on Enforce.   Can we just use the 12c client on enforce to connect to the new Oracle 19c Server?

    Thanks
