How do I clear my proc cache?
Use DBCC FREEPROCCACHE to clear the plan cache carefully. Clearing the procedure (plan) cache causes all plans to be evicted, and incoming query executions will compile a new plan, instead of reusing any previously cached plan.
What is SQL buffer cache?
In SQL Server, the buffer cache is the memory that allows you to query frequently accessed data quickly. When data is written to or read from a SQL Server database, the buffer manager copies it into the buffer cache (aka the buffer pool).
What is a file server application maintains a buffer cache of data?
Whenever data is written to or read from a SQL Server database, it will be copied into memory by the buffer manager. The buffer cache (also known as the buffer pool) will use as much memory as is allocated to it in order to hold as many pages of data as possible.
Can a buffer and plan cache be reused?
Yes. The buffer and plan cache associated with the database before restore are not related to the database post-restore, so they will be cleared. To all intents and purposes the restored database is a completely separate, unrelated entity. There is nothing in cache that can be reused.
Is there a way to clear cache in SQL Server?
Flushing all the cache is not an option. I’m using SQL Server 2008 and SQL Server 2008 R2. There is no way of doing this. DBCC DROPCLEANBUFFERS doesn’t accept any parameters for a specific database or object.
Is the cache associated with the database after restore?
The buffer and plan cache associated with the database before restore are not related to the database post-restore, so they will be cleared. To all intents and purposes the restored database is a completely separate, unrelated entity. There is nothing in cache that can be reused.
Is there anything in cache that can be reused?
To all intents and purposes the restored database is a completely separate, unrelated entity. There is nothing in cache that can be reused. Interesting question and (now I see that @MarkStorey-Smith has answered I hesitate to answer – so accept his since he answered first) I decided to do some checking.
