    Unanswered: Transparent gateway to DB2 OS/390

    Is DDF required for Oracle to access DB2 data on the Mainframe?
    If not, how is Oracel-OS/390 configured for this access? TIA

    Hello db2cics,

    We use the transparent gateway to access DB2 on our 3090 mainframe. I don't the ins and outs of how it was configured, but if you list specific questions, I can find out tomorrow. You can start by telling me what DDF stands for.

    Paul, thanks for your reply.
    DDF - Distributed Data Facility
    It's a DB2 feature that allows applications running in a remote application requester (Client) to access DB2 data on the mainframe(Server).

    One way for a Client requester (running say on Windows) to access DB2 on the mainframe is via DB2 Connect. DB2 Connect provides the link between the remote requester (Client) and Server(DB2).

    Another way to access DB2 data on the mainframe is via Transparent Gateway to DB2. Does this setup require DDF as well to access DB2 data on the mainframe? If not, how does Transparent Gateway to DB2 'talk' to the mainframe to access DB2 data?

    According to the DB2 people here, DDF always has to be there. On top of that you can then use the Oracle gateway, ODBC, or any other compatible interface.

    So yes, DDF is required for the Oracle Transparent Gateway.
