Syspolicy Phantom Health Records

SQL Server comes with a default SQL agent job installed (for most installations) to help manage the collection of system health data. I would dare say this job is ignored by most people and few probably even know it exists. This job is the syspolicy_purge_history job.

SQL Server Extended Availability Groups

It may come as no surprise to many that Microsoft has hastened the SQL Server development cycle. Furthermore, it may be no surprise to many that Microsoft has also hastened the patch cycle for SQL Server.

Extended Events File Initialization Failure

One of the recommended methods to trap payload data in an XE session is via the use of the event_file target. Sending data to a file has numerous benefits such as being able to take the trace and evaluate the trace file from a different machine (locally to that machine).

Profiler for Extended Events: Quick Settings

As of SSMS 17.4 we have been given the ability to control XEvents Profiler just a tiny bit more. For what it is worth, we as Database Professionals love to be able to control our database environment. So this teeny tiny bit of new control ability is potentially a huge win, right?

SQL Server User Already Exists – Back to Basics

One of my all-time favorite things in SQL Server is security. No matter what, it always seems that there is a new way to abuse permissions. When people abuse their access level or abuse the way permissions should be set in a SQL Server environment, we get the pleasure of both fixing it and then trying to educate them on why what they did was wrong and how to do it the right way.

Database Corruption and IO Errors

A quick way to have your day turned upside down and rip your gut out with nerves and anxiety is to come in one day to find that users are panicked, applications are not working and the HelpDesk team is curled up in the fetal position in the corner. Why? The sky is falling and everybody thinks the database has blown up. You appear to have a corrupt database and nasty IO errors.

Checking the Health of your CLR

Having a tool to be able to monitor CLR health will be essential as you deploy more and more managed code within SQL Server. Extended Events offers a great lightweight means to do just that. This article shows how to deploy a session that will capture the various changes with CLR objects within our database environment. In addition, you will be able to capture various conditions related to performance or problems with the managed code. You may even recognize some of the CLR events from the system_health session.

SQL Server Configurations – Back to Basics

One thing that SQL Server does very well is come pre-configured in a lot of ways. These pre-configured settings would be called defaults. Having default settings is not a bad thing nor is it necessarily a good thing.

Common Tempdb Trace Flags – Back to Basics

In this article I introduce you to some basics in regards to default behaviors and settings in tempdb along with some best practices. It is advisable to investigate from time to time some of these recommendations and confirm what we are really being told so we can avoid confusion and mis-interpretation.

Changing Default Logs Directory – Back to Basics

In this article I will explore altering the default logs directory location. Some may say this is no big deal and you can just use the default location used during install. Fair enough, there may not be massive need to change that location
