    many, many posts with this error code
    Code:
    12154, 00000, "TNS:could not resolve the connect identifier specified"
    // *Cause:  A connection to a database or other service was requested using
    // a connect identifier, and the connect identifier specified could not
    // be resolved into a connect descriptor using one of the naming methods
    // configured. For example, if the type of connect identifier used was a
    // net service name then the net service name could not be found in a 
    // naming method repository, or the repository could not be
    // located or reached.
    // *Action:
    //   - If you are using local naming (TNSNAMES.ORA file):
    //      - Make sure that "TNSNAMES" is listed as one of the values of the
    //        NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
    //        (SQLNET.ORA)
    //      - Verify that a TNSNAMES.ORA file exists and is in the proper
    //        directory and is accessible.
    //      - Check that the net service name used as the connect identifier
    //        exists in the TNSNAMES.ORA file.
    //      - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
    //        file.  Look for unmatched parentheses or stray characters. Errors
    //        in a TNSNAMES.ORA file may make it unusable.
    //   - If you are using directory naming:
    //      - Verify that "LDAP" is listed as one of the values of the
    //        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
    //        (SQLNET.ORA).
    //      - Verify that the LDAP directory server is up and that it is
    //        accessible.
    //      - Verify that the net service name or database name used as the
    //        connect identifier is configured in the directory.
    //      - Verify that the default context being used is correct by
    //        specifying a fully qualified net service name or a full LDAP DN
    //        as the connect identifier
    //   - If you are using easy connect naming:
    //      - Verify that "EZCONNECT" is listed as one of the values of the
    //        NAMES.DIRETORY_PATH parameter in the Oracle Net profile
    //        (SQLNET.ORA).
    //      - Make sure the host, port and service name specified
    //        are correct.
    //      - Try enclosing the connect identifier in quote marks.
    // 
    //   See the Oracle Net Services Administrators Guide or the Oracle
    //   operating system specific guide for more information on naming.

    You can lead some folks to knowledge, but you can not make them think.
    The average person thinks he's above average!
    For most folks, they don't know, what they don't know.
    Good judgement comes from experience. Experience comes from bad judgement.
