• .NET Development "Stored Procedure" or "Query"?

  Hello, me again! I found myself a bit confused about "query"  and "stored procedure" in access. Are they the same thing However, I do suspect this is ture as after some googling I found that varies articals mentioned "stored procedures" are actually created in MS Access for Sql server.

Am I getting this idea right or not     If I do get the point right (which mean ...Show All

• SQL Server SQL Server responding very slow

  Hi, we are trying to build a very large database. After reaching a database size of around 2.8TB the SQL server performance has come down drastically. The response time is so high that its taking 2 mins just to connect to the server. Other database operations are timing out. The machine is a 4 proc, 8GB RAM machine. The disk storage is derived from SAN. How do I determine what resouce is actually causing the bottleneck. I tied running some performance counters. CPU usage is avg at 70-80% with a max of 95% at times. SQL Server is using memory equal to 6-8GB on avg and peaking to 9GB at times. Another thing which is causing confusi ...Show All
