Welcome to the 22nd edition of Log Buffer, a weekly compendium of postings and news from database-related blogs across the Internet.
Starting things off with a bang is Peter Zaitsev and his MySQL Performance Blog where he records his observations on a recent set of benchmarks for both MySQL and PostgreSQL. He offers some comments on the InnoDB concurrency scaling issue that some might not be aware of (as indicated in the comments). Dropping in for Database Soup, Josh Berkus also takes a look at the same set of benchmarks in Validating PostgreSQL Performance.
Speaking of PostgreSQL, Devrim Gündüz writes in Devrin's PostgreSQL Diary about the public release of PostgreSQL version 8.2. With respect to updates, if your interest is DB2, check out Fred Sobotka's DB2 News & Tips where he provides links to new FixPaks for DB2 versions 8 and 9.
Switching back to performance, Doug Burns pens in Doug's Oracle Blog a Statspack success story and then begins looking at a Statspack example to show its value to the Oracle DBA. He continues looking at the example in Part 2 and Part 3. Doug compares the performance between two environments, his organization's and the vendor's. As many of us DBAs have faced, the vendor claims things perform just fine on its system... but is it an apples to apples comparison? Mr. Burns delves in to find out. Jonathan Lewis also scribbles on Statspack at the Oracle Scratchpad, explaining how to save the statistics while taking new ones by creating a "stats table" for that purpose.
Marco Russo at SQL BI points us to a new paper on Microsoft SQL Server 2005 Analysis Services which covers a case study in hardware tuning for a large data warehouse (based on Barnes and Noble's sales and inventory analysis requirements). If you're responsible for administering SSAS for your organization, you may want to take a look at this document on Project REAL from the folks at Unisys.
Staying on the SQL Server performance track, at the Ji Village News Haidong Ji blogs about rebuilding full text scripts. Haidong worked with some folks from Microsoft at the recent 2006 Professional Association of SQL Server to come up with this script.
Concluding the topic of database performance we travel over to the Eric S. Emrick Blog where he writes about Increasing the Longevity of Your CPU. Proper optimization can sometimes eliminate the need for additional (and costly) hardware purchases. Mr. Emrick proposes the questions to ask to help identify where optimization efforts can make the greatest impact.
Switching over to security, at the Oracle Security Blog Integrigy's CTO, Stephen Kost, writes about "mystery patches" for version 126.96.36.199 from the Oracle October 2006 Critical Patch Update scheduled to finally be available on December 15, 2006.
On the MySQL front, Paddy Sreenivasan writes an entry for the Zmanda Blog about how ZRM for MySQL can be used to detect malicious activity by examining database backups. Examining the logs is a good way to determine what happened after the fact.
Are you carrying a database-related certification and wondering about how your salary stacks up with others carrying the same cert? Check out Craig Mullins' post at his Perspectives on Database Management blog on DBA salary levels. Not surprisingly, certified DB2 and Oracle DBAs make more than their Microsoft certified counterparts. However, the good news for all DBAs is "average salaries are up."
Speaking of certifications, if you are a Microsoft Most Valuable Professional (MVP) or Microsoft Certified Trainer (MCT), Brian Lockwood, the owner of ApexSQL, is offering a free set of tools, the ApexSQL Universal Studio, according to the Apex SQL Tools Blog.
Want to enhance your knowledge by attending the 2007 MySQL Users Conference? Head over to Jay Pipes' Design, Develop, Discover, Define and read a post about a new survey on MySQL features and usage. If you fill it out you have a chance to win a free pass!
One of the neat things about an Open Source product like MySQL is we can track the changes in code. Mike Kruckenberg has done just that in his blog and has made some interesting observations after wading through code commits over the last few weeks.
In the "Tips and Tricks" department, read at OracleBrains.com how to recognize the Oracle release number. Along those same lines, find out how to Get the Domain Name of Your SQL Server Machine at SQL Server Code, Tips and Tricks, Performance Tuning. Looking to install Firebird on your new Vista machine? Look no further than Peter van Ooijen's post at Peter's Gekko on Firebird database, VS 2005 (sp1) and Vista. Finally, Tony Rogerson rambles about how to trace trigger execution using SQL Server Profiler.
Looking for a diversion that involves some SQL coding? Check out Lucas Jellema's Writing a Word Search puzzle solver in SQL at the AMIS Technology Blog. Along the same lines, take a look at Paul Nielsen's blog entry of Short Range Scan Mr. Spock where he begins posts about his efforts to create SQLTrek, a port from DEC-Trek which is a port from SuperTrek. Finally, read on Peter DeBetta's work to get his iPod/iTunes library into SQL Server over at his SQL Programming Blog.
