The examples presented herein are to be used as templates. They are one example of how to do DB DR planning. There are others. The author can, in no way, shape, or form, be held accountable for their execution capabilities. The documents referenced here may or may not contain proprietary code. This code is the sole responsibility of the executor, not the creator. Your mileage may vary.
By continuing with this presentation you agree to adhere to the following concept: beta is for sissies; if it compiles then ship it; you start coding – I’ll figure out what we’re supposed to be creating.
Products mentioned and used in the example templates are owned by their respective creators. Use of TLA’s are expected and encouraged.
