Q:

What is Log Shipping?

Answer

Log shipping is the process of automating the backup of database and transaction log files on a production SQL server, and then restoring them onto a standby server. Enterprise Editions only supports log shipping. In log shipping the transactional log file from one server is automatically updated into the backup database on the other server. If one server fails, the other server will have the same db and can be used this as the Disaster Recovery plan. The key feature of log shipping is that it will automatically backup transaction logs throughout the day and automatically restore them on the standby server at defined interval.

Q:

Explain different ways of creating a thread. Which one would you prefer and why ?

Answer

There are three ways that can be used in order for a Thread to be created:


A class may extend the Thread class.


A class may implement the Runnable interface.


An application can use the Executor framework, in order to create a thread pool.


The Runnable interface is preferred, as it does not require an object to inherit the Thread class. In case your application design requires multiple inheritance, only interfaces can help you. Also, the thread pool is very efficient and can be implemented and used very easily.
