• SQL Server Use of Priority Boost in Cluster

  Hi, I am running SQL Server 2000 (SP3A) Enterprise on Windows 2000 Cluster, and am currently experiencing performance slowness. Among the many things to be looked at, I want to know particularly whether I can sp_configure the SQL Server priority boost to 1 I read an article from Microsof ( http://support.microsoft.com/kb/319942/ ) that this is not to be done in clusters. I also have read discussions from other DBAs that it may be OK. The cluster is a 2-node cluster, each owns one named instance of SQL Server. And the cluster is dedicated to running SQL Server. Any help will be greatly appreciated. I have personally went "round and round" regarding the priority boost setting and I al ...Show All

• .NET Development Odbc SCHEMA Issue

  Hello everyone, This is my issue. For the longest while i've been reasearching and trying to figure out how, when using and ODBC connection, do I get the database schema, withouth having to execute an sql statement first.
