Question

I think there are some steps to enable SQL Cache Depdndency :

Enabling notifications, changes in web.xml and then using Cache Dependency object.

Please help how do I pass through them ?

Answer 1

Have a look at this post. It takes you through using the Aspnet_regsql.exe tool, which sets it up for you.

Here is an excerpt from the above post:

...To enable a cache dependency on a particular database, run this command:
aspnet_regsql.exe -S server -U user -P password -d database -ed

This creates a new table, AspNet_SqlCacheTablesForChangeNotification, 
in the designated database. Next, several AspNet_SqlCacheXxxx stored procs
are created in the same database.

Then look at this post from MSDN for an overview, with lots of How-to links.
