Margie s Travel operates a Web-based storefront that customers can use to pur chase airline tickets, make hotel reservations, book rental cars, schedule cruises, and purchase full vacation packages. It has just implemented a new addition to its Web site that enables customers to purchase items related to travel such as luggage, baggage tags, sunglasses, and swimsuits. However, customers are very upset with the new Web site because it is extremely slow and cumbersome. Anal ysis has traced the cause of the problem to the new product functionality. Because there is a large number of requests being processed, and not enough memory exists to cache all the necessary data, disk contention is occurring for the product catalog (which is stored on a RAID 5 array). Management wants this problem fixed immediately without adding new hardware, and performance is the top priority. Choose the best option to meet the business needs. A. Add additional files to the database. B. Add additional filegroups to segregate the data. C. Change the RAID 5 configuration to a RAID 0 configuration. D. Change the RAID 5 configuration to a RAID 1 configuration.

When index keys are updated, the row in the index must be moved to the appropriate position in the index (which is not applicable for included columns). The result is that the update is split into a delete followed by an insert. Depending on the internal fragmentation of the index pages, this might also cause page splits. Consider the following simple performance test on the Test.IndexInsertTest table containing 1,000,000 rows. 10,000 rows will be inserted in each test, and the table will be re-created between tests. First, the insert is performed against the table without any non-clustered indexes, then it is performed with one non-clustered index, and finally, with five non-clustered indexes.

Migrating to a highly available architecture does not happen overnight. In fact, the migration process to high availability is a process that never ends and is a continuous spectrum of changes to be implemented. This lesson provides a general outline for making continuous improvements in availability.

CREATE TABLE Test.IndexInsertTest ( PKCol UNIQUEIDENTIFIER NOT NULL DEFAULT NEWSEQUENTIALID() PRIMARY KEY CLUSTERED ,Col1 INT NOT NULL ); INSERT Test.IndexInsertTest (Col1) SELECT TOP(1000000) ROW_NUMBER() OVER (ORDER BY message_id) AS Col1 FROM sys.messages AS sm CROSS JOIN ( SELECT TOP(15) 1 AS Col FROM sys.messages ) AS x; -- Rebuild the table s clustered index.

You should add more RAM as a long-term solution 3 The graphical execution plan in SSMS enables you to analyze a query plan and receive assistance to improve the query performance You can use SQL Server Profiler to capture a trace when a script containing the queries you want to analyze is running, or when you execute the queries directly by typing them into the Query Editor You can use the DTA to tune databases and create an optimized query environment 4 The SQL Server: SQL Statistics object provides counters to monitor compilation If these counters indicate a high number of recompiles, you then need to look at the SP:Recompile and SQL: StmtRecompile event classes in the Profiler trace to determine which stored procedures are recompiled 5 You can use the Deadlock graph event group in SQL Server Profiler.

After this lesson, you will be able to:

Following is the first test, without any non-clustered indexes defined on the table. The execution plan for this insert statement is shown in Figure 7-6.

Develop a strategy for migration to a highly available environment. Analyze the current environment. Ascertain migration options. Choose a migration option.

You can have three different categories of standby technology: hot, warm, and cold. These terms are very often misused within this industry. The standby category that a particular technology fits into does not have to do with the following:

INSERT Test.IndexInsertTest (Col1) SELECT PKCol FROM Test.OtherTable;

This presents a graphical description of the tasks and resources involved in a deadlock 6 You can use the SQLServer:Databases:PercentLogUsed counter to trigger a SQL Server performance condition alert You could, for example, use this alert to start a transaction log backup..

A technology is categorized based on the detection mechanism provided and the way it is configured.

A cold standby is not relevant for high-availability architectures. This is a spare server that you can employ if the primary server fails. It does not necessarily have any software installed or hardware configured and is not receiv ing any updates or data.

The estimated query cost for the insert statement in this test was 0.74, and SQL Server touched 32,190 pages in the Test.IndexInsertTest table while performing the inserts. Following is the second test with one non-clustered index defined on the table. The execution plan for this insert statement is shown in Figure 7-7.
