We care, we listen, and we want to serve you better! It's been too long since I asked readers for comprehensive feedback about how you think we're doing here at SQL Server Magazine UPDATE. This week, I'd like to gather some basic technical information about you, your SQL Server deployments, and what you like or don't like about SQL Server Magazine UPDATE.
I know you're busy, but we'd appreciate you taking a few minutes to help us better serve your needs. Feel free to answer as few or as many questions as you like or to send me information that I didn't think to ask about. Email your answers directly to me at firstname.lastname@example.org.
- Tell me about you and your environment. What is your role? How long have you been working with SQL Server or another relational database management system (RDBMS)? Which versions of SQL Server are you running, and what databases do you work with in addition to SQL Server? If you're running SQL Server 7.0 or earlier, do you plan to upgrade to SQL Server 2000? Are you running SQL Server on Windows Server 2003, Windows 2000, or Windows NT? What level of experience do you have with SQL Server—do you consider yourself a novice, a knowledgeable veteran, or an expert? Do you regularly use Analysis Services, full-text indexing in SQL Server, or SQL Server 2000's integrated support for XML? What are your favorite SQL Server-related third-party products and why do you like them? What technical conferences do you attend regularly? Do you belong to a local SQL Server users group?
- Tell me about SQL Server. What are your five favorite SQL Server features? What are five new features that you'd like to see in the next version? What are your five least favorite SQL Server 2000 behaviors? How big is your largest database (in number of rows or total disk space)? What is the peak number of transactions per second that your database handles?
- Tell me about SQL Server Magazine UPDATE. What do you like best about SQL Server Magazine UPDATE? What do you like least about SQL Server Magazine UPDATE? What type of content do you prefer in SQL Server Magazine UPDATE: how-to, tutorial, opinion, or another kind of information? Can you remember a particular SQL Server Magazine UPDATE commentary that you enjoyed—or one that wasn't quite up to par? Do you prefer that complete articles appear in the text of the newsletter, or would you rather have hyperlinks to online articles?
Let us know if we've forgotten to ask anything that you feel is important so that we can include those questions in our next reader poll. And thank you for your feedback. We'll listen and we'll use your comments. We want to make SQL Server Magazine UPDATE the best newsletter it can be.
P.S. Last week SQL Server Magazine UPDATE included a news item about a free Yukon seminar that Microsoft is offering during the Microsoft Professional Developers Conference in Los Angeles on October 28. Microsoft will provide free pizza and other refreshments. Attendees will get to meet SQL Server Product Unit Manager Euan Garden and other members of the SQL Server Development team and learn about the next SQL Server release, Yukon. The presenters need to estimate how many people will attend this event. Please register for the event online at http://www.sswug.org/eventinterest.asp.

2. SQL SERVER NEWS AND VIEWS
(contributed by Paul Thurrott, email@example.com)
In July, Microsoft released a critical security fix, warning users that attackers could use the specified vulnerability to take over users' systems and wreak havoc on the Internet. A month later the infamous MSBlaster worm exploited that vulnerability. Yesterday, Microsoft released another critical security fix that fixes a vulnerability that's painfully similar to the one that led to MSBlaster. If you didn't feel sufficiently warned the first time around, take this warning to heart: You need to install this fix immediately.
The fix, one of three detailed in Microsoft Security Bulletin MS03-039 (Buffer Overrun In RPCSS Service Could Allow Code Execution), supersedes and includes the fix for the earlier vulnerability, detailed in Microsoft Security Bulletin MS03-026 (Buffer Overrun In RPC Interface Could Allow Code Execution). As with the original vulnerability, the new vulnerability that MS03-039 fixes involves the remote procedure call (RPC) technology in various Windows NT-based Windows versions, including Windows Server 2003, Windows XP, Windows 2000, NT Workstation 4.0, NT Server 4.0, and NT Server 4.0, Terminal Server Edition (WTS).
If you have a recent Windows version, you can simply download the patch from Windows Update or Auto Update, features that are included with your OS. For more information about the security patch or the other tools Microsoft offers to protect your system, visit the Microsoft Web site.
The New York Times reported last week that Oracle's revenue from licenses for new software fell 6.7 percent in first quarter 2003 from the same period a year ago. The decline appeared to be greatest in Oracle's database business, where it competes with Microsoft and IBM. License revenue for the database unit was down 7 percent from a year ago, to $408 million. Oracle's other software products had new license revenue of $102 million, down 4 percent from the same quarter in 2002.
Oracle attributed the drop to unexpectedly slow sales in August and the disruptions from reorganizing its North American sales force. Oracle had projected growth in revenue from licenses for new software of 2 percent to 12 percent, after reversing a long trend of declines with a gain in the previous quarter. Wall Street traders reacted to the news by selling other technology stocks last week.
The voting has closed in SQL Server Magazine's Instant Poll for the question, "Do you use SQL Server 2000 Developer Edition?" Here are the results (+/- 1 percent) from the 273 votes (deviations from 100 percent are due to a rounding error):
- 51% Yes, we've used it for some time
- 6% Yes, we got it when Microsoft reduced the price
- 11% No, but we plan to now that the price has dropped
- 32% No, and we don't plan to

The next Instant Poll question is "Has your organization patched its systems against the most recent Windows bug—a vulnerability in the RPCSS service?" Go to the SQL Server Magazine Web site and vote for 1) Yes, our IT group applied the patch immediately, 2) No, IT hasn't patched our systems yet but plans to, 3) No, IT probably won't patch our systems, or 4) I haven't heard about the latest vulnerability.

The connection string is essential for connecting your ADO database applications to SQL Server. In his SQL Seven column "ADO Connection Strings," Michael Otey illustrates the seven most common connection scenarios. Read this September SQL Server Magazine article at
Timc has SQL Server 2000 running on a new quad-processor server that has 8GB of RAM and uses Address Windowing Extensions (AWE). The system queue is always less than .2 and the buffer cache is always at 99 percent. However, Timc's cache hit ratio is consistently about 64 percent. Timc wants to improve the cache hit ratio, and his research suggests that he needs to add more memory. However, he's not convinced that more memory is the answer. How can Timc improve his system's cache hit ratio? See what other DBAs have said, and offer your opinion, on SQL Server Magazine's Performance forum.

Q. I have a Visual Basic (VB) application that connects to a SQL Server 2000 database. How can I verify that the client machine has a TCP/IP sockets Net-Library connection to the database?
A. You can easily determine the Net-Library that a particular connection is using by looking at the sysprocesses table's net_library column in the master database. The master..sysprocesses table contains one row for each connection to the server; a server process ID (SPID) identifies each connection. The following query returns the Net-Library that the connection is using:
sysprocesses WHERE spid = @@spid
Running this T-SQL query from your application lets you determine which Net-Library a connection from your application is using. Of course, you can also manually inspect the sysprocesses table from Query Analyzer to get the information you're looking for. TCP/IP will be the value for the net_library column if you're connected through a TCP/IP sockets connection.
