Rittman Mead - Delivered Intelligence

I feel like I’m introducing the Beatles… though I think Kellyn Pot’Vin calls them the “DBA Gods”.  Today I’ll be talking about Cary Millsap, and tomorrow I’ll introduce our other special guest: Alex Gorbachev. As many of you know, I grew up as a DBA (albeit, focusing on data warehouse environments) before transitioning to development… [...]

This article is the final one in a series about OBIEE and performance. You can find the previous posts here: Introduction Test – Define Test – Design Test – Build Execute Analyse Optimise Summary The key to long term, repeatable, successful performance optimisation of a system is KNOWING where problems lie and then resolving them [...]

Potato potato? When I first drafted this blog post, I gave it the title “Tuning”, rather than “Optimising”. Tuning is the word used so often in the context of performance, but it can actually be a bit misleading. A system that has fundamental design flaws doesn’t need “tuning” – it needs redesigning. Tuning can end [...]

This part of the OBIEE performance cycle is the one which arguably matters most. Having defined what we’re going to test, built a means by which to test it, and executed that test, we now need to sift through the tealeaves and work out what the data we collected is telling us. Except we’re not [...]

Having designed and built our tests, we now move on to looking at the real nitty-gritty – how we run them and collect data. The data that we collect is absolutely crucial in getting comprehensible test results and as a consequence ensuring valid test conclusions. There are several broad elements to the data collected for [...]
