A 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: Response Time analysis showed us that the database was CPU bound
- Click 3: We isolated the SQL statements that were causing the database to be CPU bound
- Click 4: We Explained the SQL statement having the highest aggregate CPU cost and determined that a high quality index was needed
- Click 5: 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.
THAT'S IT - JUST FIVE MOUSE CLICKS 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: While you're here and waiting for your download to complete, why not spend a minute checking out DBI's performance management tools for IBM DB2 LUW?
