RE: ''''Access is denied''''

At a guess, SQL Server doesn't have access to read the registry. What account are the services running under? Are the any policy settings explicitly restricting access to the registry? Have you used Spotlight before?

SQL Server Database Index Performance

  • Article

When it comes to auditing index use in SQL Server databases, I sometimes get overwhelmed. For example, how to do you go about auditing indexes in a database with over 1,500 tables? While auditing a single index is relatively straight-forward, auditing thousands of them in multiple databases is not an easy task. Whether the task is easy or not, it is an important task if you want to optimize the performance of your SQL Server databases.

Clustering for Indexes

  • Article

There is nothing spectacular about using indexes per say. However, on many occasions I have come across a variety of SQL coders that never consider validating that the index they think they are using is efficient or even being used at all. We can all put indexes on the columns that we think will be required to satisfy individual queries, but how do we know if they will ever be used. You see, if the underlying table data is constructed, contains, or is ordered in a particular way, our indexes may never be used. One of the factors around the use of an index is its clustering factor and this is what this article is about.
