DGA, Direct GCOS Access, is a network interface available for G&R Glink that allows it to connect directly from the user workstation to the Bull mainframe without passing through a gateway or a front-end.
DGA is only available for the G&R Glink terminal emulations and APIs:
DGA connections from Glink to the Bull hosts use native Bull DSA protocol, and bring the full power of the native protocol down to the workstation. In effect the workstation is transformed into a fully functional Bull network node having peer-to-peer communication with GCOS that is as powerful and efficient as peer-to-peer communication between two GCOS systems.
In addition to providing full DSA configurability so that Glink can connect to any GCOS7 (IOF, TDS) or GCOS8 (TSS, TP8) application, DGA utilizes its DSA network node functionality in order to:
Considerations such as network monitoring, load balancing, and fail-safe configuration might make a Ggate/Gproxy solution preferable to DGA, but for the absolutely most efficient direct connection from a workstation to a GCOS system then DGA cannot be beaten.
