Hello:

Perhaps a very simple question regarding how to access the DB files in a multiprocessor machine.  

Is it possible one file to be open/accessed by more than one processor at a time?

Even modified?

Some link to documentation will be welcome.

Thanks,

Juarrero

Hi Juarrero,

So a sql server database file can only be accessed by a single sql server service at a time, however sql server is multi core aware and where appropriate will use parallel processing which splits the load of a requested query across multiple cores

Thanks
