    fatal two-task communication protocol error

    Hello,

    I am encountering a problem when connecting to oracle 10g server from a third party tool(Rogue Wave DBTools++).

    ORA-03106: fatal two-task communication protocol error

    I have a Oracle 10g Server running on Solaris 9 box.
    I tried to connect to the server using a Rogue wave API which provides diffrent methods to connect to database using c++.

    Program failed to connect to the database which uses unicode character sets like UTF8 and AL32UTF8
    Program succeded when character set was changed to US7ASCCI.

    Could anyone point out what could be the problem.
    Any help appriciated in this regard.

    Thanks
    Satya

    Hi,
    This could have happened due to Character set incompatibilities between your third party software and database.

    Can u please post the character set of you third party software and the database

    Basically your client's character set should be sub set of the database character set.

    For exp, if you client character set is UTF8 but your database character set is US7ASCII, then connection will not happen.

    Because UTF8 is a super set of US7ASCII.
