No matter what Windows operating system you re using, you can access Event Viewer and view basic operating system logs These include the System, Security, and Application logs All three have information that can help you troubleshoot problems with your SQL server The System log holds system-level events such as when services start and stop, and can often give you insight into why your system may not be working The Application log holds information logged specifically by applications such as SQL Server SQL Server logs events such as when SQL options are changed and when SQL services start and stop The Security log holds auditing information Sometimes the reason SQL doesn t start is related to the authentication of the account starting the service If the service can no longer authenticate (for example, because the domain account s password has expired), then the service using that account will fail

FIGURE 10-12

The StoredProcedureMultipleResult return type contains the GetResults(Of T) method to differentiate the two result sets by simply providing the class type we want to retrieve. Listing 2-22 shows the method s usage.

Advanced Tab If you click the Advanced tab, you can also manage a few additional memory and processor settings, shown in Figure 10-13 First, Windows Vista is set to provide more processor cycles to applications than to Windows Vista background processes As a general rule, you should keep this setting to ensure that performance

In this exercise, we ll launch Event Viewer and take a look at the available logs Exercise 19: View Event Viewer Logs 1 Choose Start | Administrative Tools | Event Viewer Alternatively, you could launch Computer Management by clicking Start, right-clicking My Computer, selecting Manage, and then clicking Event Viewer Select the Application log You should see a display similar to Figure 1-22

If I use a Custom configuration on the Visual Effects tab, which settings have the most system performance impact What does Windows Vista do when the Adjust for performance option is used Any settings that have animated features, such as shading, tend to have an impact on performance You can also clear the Use visual styles on windows and buttons option to help reduce some of the visual hits When this option is used, the system will look more like Windows XP You ll lose the basic Vista interface appearance

2 Scroll through the logs until you find an event with a source of MSSQLSERVER Double-click the event to open it and read it 3 Notice that some events are information (indicated by an icon of an i within a bubble), some are warning (an exclamation mark in a yellow triangle), and some are errors (an X in a red circle) 4 Select the System log and browse through it Note that since SQL Server is not an Operating System service, you won t find MSSQL Server source errors in the System log 5 Select the Security log and browse through it If auditing is not enabled on your system, you will not have any entries in the Security log TIP Some Event Viewer log entries are hard to interpret If you come across one that looks a little cryptic, check out wwweventidnet This has proven to be a great resource to a lot of techs
