For this lab, you should bring with you copies of SYSIBMADM Snapshot Catalog Views (detailed instructions and scripts will be provided separately). In this lab, you will receive dozens and dozens and dozens of SQL Snapshot commands (on CDROM) to analyze your database's performance data, you will learn what the numbers and metrics mean, and you will graduate fully equipped to conquer amazing performance tuning miracles for your organization...]]> http://www.dbisoftware.com/blog/db2_performance.php?id=187 Wed, 10 Mar 2010 02:22:49 +0000 DB2 Performance How-To http://www.dbisoftware.com/blog/db2_performance.php?id=187#cmt <![CDATA[DB2 LUW Performance: Scalability, Availability, and Disaster Recovery]]> Database and Hardware wars. The DB2Night Show™ Episode #4 featured special guests from the IBM Toronto Lab who gave us an outstanding introduction to DB2 pureScale - catch the WMV replay if you missed it. On the heels of DB2 9.7 Oracle enablement, DB2 pureScale is an exciting response to Oracle RAC. But is pureScale right for your organization, or should you be considering Xkoto GRIDSCALE instead? First and foremost, IBM DB2 PureScale is NOT a Disaster Recovery solution, but Xkoto GRIDSCALE is. How else are these technologies different?]]> http://www.dbisoftware.com/blog/db2_performance.php?id=183 Tue, 09 Feb 2010 07:03:45 +0000 DB2 Performance Best Practices http://www.dbisoftware.com/blog/db2_performance.php?id=183#cmt <![CDATA[DB2 LUW Performance: I/O Optimization and Solid State Disk (SSD)]]> Unleashing the value of Solid State Drives. Of course, I was thrilled to see DBI's new ad as well (grin). The article puts forth several good ideas about I/O tuning and begs for greater details. Whether you have SSD or not, the principle ideas of the article still apply to "faster storage" versus "slower storage".

In late breaking news today, Orickle announced preliminary plans for the next version of its world dominating database 13G. Version 13G will include new features such as DB3 LUW Enablement and nano compression. A senior Orickle executive who requested anonymity said "We skipped 12 because 13 is a lucky number, and 'G' now stands for Global domination. We lost some serious market share to DB3 9.7 but we believe we can win global database dominance back with our superior marketing, sales, and negotiation tactics."
