Unlike troubleshooting and problem solving, where you have a specific problem that needs to be uncovered and solved, tuning and optimization involves more gradual changes to the system. In some cases, the performance of the system can be optimized by making changes in the application or in the way SQL Server has been configured. In other cases, there is not much that you can do besides adding more hardware. In order to create the most optimal system possible, you must complete many of the steps that you do when troubleshooting a problem. However, before you proceed, you must determine if there is an actual problem. This is not always easy. When tuning a SQL Server system, it is usually recommended that you take the approach to tune the application first and then tune the SQL Server instance.

It is recommended that the application and SQL statements be tuned first and then the database system. This is to allow the possibility of reducing system resources by using more efficient indexes, partitioning, and hints. By reducing resources such as CPU utilization, memory, and I/Os, you can improve performance while at the same avoiding the need to increase hardware resources.

Tuning the SQL Server instance typically involves adding more hardware to allocate more memory to SQL Server or adding more disk drives to reduce I/O latencies. As you know, there aren t a lot of SQL Server parameters that can be modified. SQL Server instance tuning typically is done by adding more hardware, which can be costly. If the application is not optimal, you can easily add more and more hardware and still end up with a poorly performing system.

It s also possible to create custom authentication adapters that verify credentials against other data sources, simply by extending the base Zend_Auth_Adapter_Interface class The child class must expose, at minimum, a constructor that accepts user credentials and an authenticate() method that verifies these credentials against an authentication provider The return value of the authenticate() method must be an instance of the Zend_Auth_Result class, with a constant indicating whether or not authentication was successful You ll see an example of one such custom authentication adapter in the next section

In order to properly troubleshoot or tune a system, you must follow a structured methodology. This methodology allows you to be scientific in your approach and to continually move forward in your tasks.

Now that you have some idea of the attitude and skills that are required for troubleshooting and performance tuning, it is time to look at some of the processes and methodologies for these tasks. Both troubleshooting and tuning benefit from using a standard methodology. So, what is a methodology A methodology is a set of rules, processes, and steps that you follow in order to perform a task in a scientific and repeatable manner.

In this section, you are introduced to performance tuning, optimization, and troubleshooting methodologies. This is the methodology that I have used for several years. You can take this methodology as a guideline and adapt it to your own needs. This methodology has several steps: 1. Make an initial assessment and establish a baseline. 2. Monitor the system. 3. Analyze the results. 4. Create a hypothesis. 5. Propose a solution. 6. Implement changes. 7. Test the solution. 8. If other problems still exist, return to Step 2; if not, exit. These steps are covered in detail in the following sections.

The first step in tuning and troubleshooting is to understand the environment. It is important to begin by gathering information in order to learn about the application and begin to understand what problems, if any, exist in the system. Some things that should be done and completely documented in this step are as follows:

Determine what the reported problem is Document database size, tuning parameters, and so on Look at the system as a whole Validate parameters
