Cache invalidation is a process in a computer system whereby entries in a cache are replaced or removed.

Fetches requested content from the application, even if cached content is available.

Simple query is not smart enough to give me the data I need. SQL Server 2005 and SQL Server 2008 have unpleasant bug that [almost] silently kills Queue Notifications:"You cannot run a statement or a module that includes the EXECUTE AS clause after you restore a database in SQL Server 2005" fixed it by running this command: explains how to use SQL Profiler to see what's going on with query notifications.2) Using Profiler helped me to find the following errors in SQL Profiler:- An exception occurred while enqueueing a message in the target queue. The database owner SID recorded in the master database differs from the database owner SID recorded in database 'Post Job Free'.

When you debug your own code -- dump more complex query and use only simple one. You should correct this situation by resetting the owner of database 'Post Job Free' using the ALTER AUTHORIZATION statement.- Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated, or you do not have permission.

In such a case, a processor changes a memory location and then invalidates the cached values of that memory location across the rest of the computer system.

Cache invalidation can be used to push new content to a client.

This is an annoyingly inefficient use of resources and developers and architects have been stuck playing cat-and-mouse trying to reduce the waste.
