    Mismatched Oracle drivers - need upgrade (10.2.0.1 to 10.2.0.5)


    Hi,

    We are running Oracle Enterprise software on various client and DB servers and we are experiencing a problem (outlined here ) where the apparent mismatch between the oracle drivers are causing the errors.

    Our db servers are using 10.2.0.4 and 10.2.0.5 drivers and the clients are using 10.2.0.1.

    Firstly, are the drivers the same on the Express and Enterprise editions so that if I update a development server using Express version (I dont have the authority to upgrade the Enterprise version nor the time to commission that) and it is successful, can I reasonably expect an upgrade to the Enterprise client versions on other servers to be safe/error free, baring environmental factors of course ?

    Secondly, can I upgrade to version 10.2.0.5 now or do I have to go to the 11g version only ?

    I hope I have explained this correctly and that it is understandable as I cannot find this sort of info elsewhere.

    Regards, George.

    How do you know it's the drivers (clients)? Oracle clients are backward-compatible and should make no difference, specially within the same version (10g).

    You can download the latest Oracle software from the Oracle Technology Network.
    If you do not have the time, then why are you wasting it on Oracle Express Edition?

    You can install version 11g anytime.
    Beside, unless there is a specific patch for an Oracle client, there are no intermediate versions (like 10.2.0.5), only one main client version for each release (10g, 11g).
