SQL SERVER – Database Mirroring and Fine-Prints – Quiz – Puzzle – 23 of 31

SQL Server Interview Questions and Answers
Print Book Available (207 Pages) | Sample Chapters

Year 2011 was a year of learning and opportunity for me. My recent book, SQL Server Interview Questions and Answers, has received such overwhelming love and support from all of you. While writing the book, I had two simple goals: (1) Master the Basics and (2) Ignite Learning. There was a constant request from the Community to take the learning of these books to the next level. Here is an article which discusses the Author’s Perspective.

Beyond Relational has come up with a very interesting concept – they have converted a few of the questions from my book into the SQL Quiz. The quiz is indeed focused on my two goals. In addition, it’s going to put the learning of the book to a higher stage. Looking at this novel concept, Vinod Kumar (Co-author) and I have decided to help every participant and reader by giving a few hints and suggestions to solve the quiz.

Notes of Vinod Kumar

DBM is a very famous method of HA options that I have seen enterprises use in their environments. The concepts are simple and well-explained. There are also fine-prints when implementing DBM, which need special attention.

Notes of Pinal Dave

“Is database mirroring a high-availability solution, or a disaster recovery solution?” When I ask this question, I keep on getting a different answer every single time. Database mirroring maintains two copies of a single database that must reside on different server instances of SQL Server Database Engine. Now, mirroring requires that the database has to be in full recovery mode and the database resides on different instances. A lesser known fact is that mirroring is also related to the Page Restore concept. Why not spend time to know what the main interesting factors related to database mirroring are? I’m sure it would be a worthwhile learning experience for you.
