1. COMMENTARY
(contributed by Brian Moran, news editor, [email protected])
Faster than a speeding Oracle.
More powerful than a DB2.
Able to outperform MySQL in a single DDL statement.
It's a bird—it's a plane—it's SQL Server on Windows!
Two weeks ago, Microsoft broke through a barrier that many people thought couldn't be broken. The company posted a nonclustered TPC-C benchmark faster than anything that Oracle or DB2 has ever published. Microsoft posted a tpmC score of 433,107 with a price per tpmC of $12.98. Microsoft achieved the score using a 32-CPU database server running the 64-bit versions of Microsoft Windows Server 2003 Datacenter Edition and SQL Server 2000 Enterprise Edition. Oracle's best score is 427,760 tpmC with a price per tpmC of $17.75. The SQL Server score costs about a third less per transaction than the Oracle system and is a little more than 1 percent faster.
You might have noticed that 64-bit Windows Server 2003 and 64-bit SQL Server aren't yet commercially available. The Transaction Processing Performance Council (TPC) site says that this configuration isn't expected to be commercially available until around the end of June. Foul, you say! No fair comparing a future version of SQL Server to shipping versions of Oracle. Calm down. The Oracle configuration mentioned above won't be commercially available until about the end of May, so the comparison is fair.
The new SQL Server score isn't the fastest TPC-C score ever; it's the second-fastest nonclustered TPC-C score ever published. A database called SymfoWARE achieved the top honor with a score of 455,818 tpmC at a price of $28.58 running on a Fujitsu mainframe-class server with 128 processors. That score is 5 percent faster than the new SQL Server score but required four times as many processors at more than double the per-transaction cost. Besides, do you know anyone running SymfoWARE?
IBM hasn't posted a nonclustered TPC-C score for DB2 since March 19, 2001, so I'm going to leave it out of the comparison because it wouldn't be fair to compare new scores to a score that's nearly 2 years old. Presumably, IBM doesn't think DB2 is competitive in this benchmark, or it would have posted a score more recently. By all standards, SQL Server, Oracle, and DB2 are the dominant database platforms. SQL Server has a long history of being more cost-effective than Oracle and DB2, but it's never been less expensive AND faster.
This benchmark should finally put to rest the argument that SQL Server can't scale to the same levels that UNIX platforms can. For years, I've argued that SQL Server is fast enough to meet the needs of almost any business application. However, my argument didn't convince die-hard UNIX database fans who like to speculate about the future load on their database server. The recent Slammer debacle shows that Microsoft still has some challenges ahead in the world of enterprise-class support and service. However, this most recent TPC-C score should give organizations the confidence that SQL Server on Windows can meet their businesses' performance needs as well as or better than anything UNIX offers. Chances are, you'll never need to support 7,200 transactions per second, but it's nice to know you can.
For more information about this and other TPC-C benchmark scores, see the TPC site at http://www.tpc.org .

2. SQL SERVER NEWS AND VIEWS
Microsoft has consolidated three of its security tools—SQL Server 2000 SQL Scan, SQL Check, and SQL Critical Update—into one download, the SQL Critical Update Kit. The kit also includes a Systems Management Server (SMS) deployment tool and the Servpriv.exe utility. The SQL Server 2000 security tools help update editions of SQL Server 2000 and Microsoft SQL Server Desktop Engine 2000 (MSDE 2000) that are vulnerable to the SQL Slammer worm. The tools scan instances of SQL Server 2000 and MSDE 2000 to help detect vulnerabilities to Slammer, then apply updates to the affected files. You can download the SQL Critical Update Kit at http://www.microsoft.com/downloads/details.aspx?FamilyId=9552D43B-04EB-4AF9-9E24-6CDE4D933600&displaylang=en .
Microsoft announced hotfixes for two known bugs. The article "FIX: Cannot Remove Microsoft SQL Server 2000 Desktop Engine After You Upgrade to MSDE 2000 SP2" (available at http://support.microsoft.com/default.aspx?scid=kb;en-us;317619 ) explains that all editions of SQL Server 2000 (Personal, Evaluation, Developer, Standard, and Enterprise) include the 8.00.194.01 build of Microsoft SQL Server Desktop Engine 2000 (MSDE 2000) on the products' CD-ROMs. If you originally used this build of MSDE and you upgrade to MSDE 2000 Service Pack 2 (SP2), you can't remove MSDE 2000 from the computer. This problem occurs only if you upgraded the MSDE release to manufacturing (RTM) build (194.01) directly to SP2. The problem doesn't occur on any other editions of MSDE 2000. The problem also doesn't occur if you first upgrade from the RTM version to MSDE 2000 SP1, then upgrade to MSDE 2000 SP2. You can fix the problem by obtaining SQL Server 2000 SP3, but the article provides a hotfix that was available before the company released the latest SQL Server service pack.
The article "FIX: SQL Server 7.0 Scheduler May Periodically Stop Responding During Large Sort Operation" describes a rare condition in which SQL Server gives you the error message "2003-02-10 17:02:54.39 ods The Scheduler 2 appears to be hung. PSS 0x5F8B3110, EC 0x5F8B32C0, UMS Context 0x050D07D8." When SQL Server processes a query that includes a large, long-running sort operation, this error message can repeat as frequently as once per minute while the query is running. In some cases, SQL Server might also be slow to respond to other requests. The article notes that, although Microsoft does support a fix for this problem, you should apply the fix only to specific machines that are experiencing the scheduler response problem. You can obtain the hotfix and read about the problem at http://support.microsoft.com/default.aspx?scid=kb;en-us;814693 .
The voting has closed in SQL Server Magazine's nonscientific Instant Poll for the question, "How many hours do you work in a typical week?" Here are the results (+/- 1 percent) from the 642 votes:
- 8% Less than 40 hours
- 18% 40 hours
- 48% 41 to 50 hours
- 17% 51 to 60 hours
- 9% More than 60 hours
The next Instant Poll question is "Do you pay attention to TPC benchmark scores?" Go to the SQL Server Magazine Web site and submit your vote for 1) Yes, we use them to optimize our own database's performance, 2) Yes, we use them to plan future database configurations, 3) Yes, we use them to plan/justify database purchases, or 4) No, we don't use TPC information.

4. RESOURCES
Running multiple database platforms is a way of life for most businesses, and many companies are running SQL Server and Oracle at the same time. Typically, the two database platforms are independent. But SQL Server's linked servers feature lets you seamlessly integrate your SQL Server applications with the tables in Oracle databases. To learn how to set up and use a linked-server connection from SQL Server 2000 to an Oracle database, read Michael Otey's March SQL Server Magazine article "The Direct Connection," available online at
http://www.sqlmag.com/articles/index.cfm?articleid=37678
Shiv recently restored a database after a hardware failure. Since the restore, his database's performance has been poor. He used SQL Server Profiler to trace the problem to the SQL statement:
SELECT * FROM Information_Schema.Columns WHERE Table_name='XXX'
This query takes as much as 20 seconds to run. Shiv has approximately 30 applications that call the SQL statement, and two of those call the statement within a tranaction. However he uses read-only locks, so he doesn't think he should be experiencing problems with blocking. Shiv has rebuilt the indexes on the schema view and has accounted for all the system settings he needed to set after the restore.

Q. A local ISP hosts our SQL Server, and I haven't been able to see or connect to named instances running on the machine. I know that SQL Server 2000 named instances don't use TCP/IP port 1433, and I've verified that the TCP/IP ports that the SQL Server instances are using are open. Do you have any suggestions?
A. Many people know how to check which ports SQL Server instances are listening to by using the SQL Server Network Utility or by simply reading the SQL Server error log. But many people seem to forget, or simply don't know, that UDP port 1434 also needs to be open to ensure that you can correctly access and browse named instances. I encourage you to read up on this requirement. Searching SQL Server Books Online (BOL) for "1434" returns three valuable hits. You'll also find information about accessing named instances in my SQL Server Savvy column from July 2001, available at http://www.sqlmag.com/articles/index.cfm?articleid=21127 . For now, here's a simple explanation. SQL Server establishes a listener service on UDP port 1434 that lets a client query the server for a list of named instances and their network configuration information. This listener service always runs on UDP port 1434 and can't be configured to run on another port.
