We have a growing population of Access users. My question is whether there is a way of lowering these user’s priorities on our SQL Server?
QuestionWe have a growing population of Access users, much to my chagrin! My question is whether there is a way of lowering these user’s priorities on the server/database. We are hoping that if the performance using Access is bad, that this will dissuade users from using Access. AnswerAt our company, we forbid users from accessing […]

To find out how your SQL Server is currently configured, right-click on the server in Enterprise Manger or Management Studio, and select “Properties”. Next, select […]
QuestionI am the DBA of a SQL Server that has the memory setting configured to “Dynamically configure SQL Server memory, and the “Maximum Memory” set to 905MB out of a possible 1151MB. When I look at the Cache Size (pages) counter, it runs about 115MB. In addition, the Buffer Cache Hit Ratio counter is fine. Why […]
Question I have read about pinning frequently accessed tables into memory rather than let them being accessed from the disk all the time. But what I wish to know is if there is any cutoff limit for the size of a table that could make it a bad candidate for pinning? Answer By default, SQL […]
