In my previous post here, I’ve discussed how we can detect fragmentation in SQL Server databases indexes using dynamic management view function sys.dm_db_index_physical_stats. In this post, I’m sharing my stored procedure which I’ve created a while ago to rebuild fragmented indexes based on the fragmentation level. This stored procedure… Read more

SQL Server 2012 allows you to store file/directories in a special table called FileTable that builds on top of SQL Server FILESTREAM technology. As per Microsoft BOL, “FileTable lets an application integrate its storage and data management components, and provides integrated SQL Server services – including full-text search and semantic… Read more

The installation process is simple, straight forward and is very similar to SQL Server 2008 / 2008 R2 setup. The procedure described is for a non-clustered… Read more

Index fragmentation can adversely affect query response time. When accessing data through an index, SQL Server must read each page in the specified range to retrieve the indexed values. If the index is highly fragmented, SQL Server may have to search many more pages, and possibly levels, to get this… Read more

There are several options available for configuring your storage media in Windows Server 2003 and Windows Server 2008. By understanding your storage options will help you to make informed decisions about SQL Server system configuration and data storage.

The SQL Server maintains all indexes defined against a table regardless of their usage. Index maintenance can cause significant amounts of CPU and I/O usage, which can be detrimental to performance in a write-intensive system. With this in mind, it makes sense to identify and remove any indexes that are… Read more

Following error dialog pops up today, when I tried connecting to SQL Server Configuration Manager on my SQL Server 2008 production server:

Cannot connect to WMI provider. You do not have permission or the server is unreachable. Note that you can only manage SQL Server 2005 and later servers with… Read more

Today the maintenance job that recycles the SQL Agent error log failed on one of our production SQL Server with the following error message:

Message: Executed as user: MyDomain\_svcSQLServer. SQLServerAgent Error: 32. [SQLSTATE 42000] (Error 22022). The step failed.

This job uses [dbo].[sp_cycle_agent_errorlog] procedure that resides inside msdb, which enables… Read more

A database server should be able to service requests from a large number of concurrent users. When a database server is servicing requests from many clients, there is a strong possibility that conflicts will occur because different processes request access to the same resources at the same time. A conflict… Read more
