Hello there, first time here :) , im having many issues trying to set up cx_Oracle module on my Ubuntu OS. My question is if the Oracle's Instant Client version it must be the same as my Oracle's Server Version ??

    Seems so.
    I did 5.0.4 it on windows, if OCI not match, Oracle will return error says attribute not supported or something like this.

    There is no Oracle requirement for the client & database libraries to be exact. For example, Instant Client 11g will connect to 10g databases.

    If you have a database on the same machine as Instant Client then you need to be careful about which tools pick up which of the two sets of Oracle libraries. This is a common problem for Windows users.

    Also on Windows you do need to match the Oracle libraries to those that whatever tool (e.g. cx_Oracle) was built with.
