In our 13th show, special guest Paul Zikopoulos, Program Director - DB2 Evangelism, IBM Software Group, provided us with fantastic information on "DB2 LUW Compression Updates". He covered compression in DB2 9.1, 9.5, and 9.7, index compression, temp compression, and even shared competitive information that compares DB2 LUW compression to Oracle and SQL Server. This Episode is a MUST SEE...

Our Shameless Marketing Moment

During this episode, DBI's short two minute sponsorship commercial included a brief live demonstration of DBI's performance analysis, tuning, and trending tools for DB2 LUW. Here's what we did:

  • Click 1: Database Triage - identify the database having the worst performance problems
  • Click 2: We performed a Table Performance analysis and discovered over 98% of database read I/O was occurring against one table
  • Click 3: We performed a Statement Workload Analysis to find ALL of the SQL driving I/O to the table
  • Click 3: We Explained the SQL statement and determined than an index was needed
  • Click 4: We passed the high CPU cost statement to the IBM Design Advisor and received validation - a second opinion if you will - that the index we thought was needed was indeed needed, and that the proposed index would provide a tremendous CPU cost reduction.
  • Bonus! We showed how we can graph the performance of a statement over time, how performance improvements can be graphically verified, and how DBI can show you the details of changes (physical design, memory, and configuration) and how the changes influenced performance!
THAT'S IT - JUST FOUR MOUSE CLICKS IN under 120 SECONDS to identify, isolate, and resolve a performance problem! We could have done it in just three clicks but didn't want to show off! icon_biggrin
