DR -- RDBMS // recommended/adequate DR Configuration Diagram --an overview

Here is a diagram to summarize what kind of configuration is recommended for having a Production Oracle Database environment with an adequate DR configuration.
The DR solution, which is a 2 tiered one (a Local DR and Remote DR) shown in below figure is completely dependent on the use of Oracle Dataguard.
I recommend Maximum Availability mode for Local DR/Standby and Maximum Performance Mode for the Remote DR. (as already shown in the figure below -- in the text box)
The figure is self explanatory but if you have any questions, I can happily answer.

You can find more info about the Oracle DR and Standby configuration in this blog...
