Using Linux Control Groups to Constrain Process Memory

Linux Control Groups [http://docs.oracle.com/cd/E37670_01/E37355/html/ol_about_cgroups.html] (cgroups) are a nifty way to limit the amount of resource, such as CPU, memory, or IO throughput, that a process or group of processes may use. Frits Hoogland [https://fritshoogland.wordpress.com/2012/

BI Forum 2015 Preview -- OBIEE Regression Testing, and Data Discovery with the ELK stack

I’m pleased to be presenting at both of the Rittman Mead BI Forums [https://www.rittmanmead.com/blog/biforum2015/] this year; in Brighton it’ll be my fourth time, whilst Atlanta will be my first, and my first trip to the city too. I’ve heard great things about

Visual Regression Testing of OBIEE with PhantomCSS

Earlier this year I wrote a couple of blogs posts (here [https://www.rittmanmead.com/blog/2014/01/obiee-regression-testing-an-introduction/] and here [https://www.rittmanmead.com/blog/2014/01/automated-regression-testing-for-obiee/]) discussing the topic of automated Regression Testing and OBIEE. One of the points that I was keen make was that OBIEE

Built-In OBIEE Load Testing with nqcmd

nqcmd ships with all installations of OBIEE and includes some very useful hidden functionality - the ability to generate load tests against OBIEE. There are lots of ways of generating load against OBIEE [https://www.rittmanmead.com/blog/2013/03/performance-and-obiee-test-build/], but most require third party tools of varying degrees

Introducing obi-metrics-agent - an Open-Source OBIEE Metrics Collector

Understanding what is going on inside OBIEE is important for being able to diagnose issues that arise, monitor its health, and dig deep into its behaviour under stress in a load test. OBIEE exposes a set of metrics through the Dynamic Monitoring Service (DMS) and viewable through Enterprise Manager (EM)

Automated Regression Testing for OBIEE

In the first article of this series [https://www.rittmanmead.com/blog/2014/01/obiee-regression-testing-an-introduction] I explored what regression testing is, why it matters, and by breaking down the OBIEE stack into its constituent parts where it is possible to do it for OBIEE. In this posting, I explore some

OBIEE Regression Testing - An Introduction

In this article I’m going to look at ways to test changes that you make to OBIEE to ensure that they don’t break existing functionality. In all but the simplest IT systems it’s common for one (planned) action to inadvertently cause another (unplanned). What IS Regression Testing?

Testing aggregate navigation on OBIEE and Exalytics

One of OBIEE’s many great strengths is aggregate navigation; the ability to choose from a list of possible tables the one which will probably give the optimal performance for a given user query. Users are blissfully unaware of which particular table their query is being satisfied from, since aggregate

Advanced Presentation Services settings for OBIEE testing & development

As John Minkjan pointed out [http://obiee101.blogspot.co.uk/2011/10/obiee-obipsconfigbasexsd.html] a while ago, the XSD (XML Schema) for the OBIEE configuration files can yield some interesting things. I've been looking at obips_config_base.xsd and found the following bits of information which I
