OBIEE Performance - Why Metrics Matter (and…Announcing obi-metrics-agent v2!)

OBIEE Performance - Why Metrics Matter (and…Announcing obi-metrics-agent v2!)

One of the first steps to improve OBIEE performance is to determine why it is slow. That may sound obvious—can’t fix it if you don’t know what you’re fixing, right? Unfortunately, the “Drunk Man anti-method”, in which we merrily stumble from one change to another, maybe

Using Linux Control Groups to Constrain Process Memory

Using Linux Control Groups to Constrain Process Memory

Linux Control Groups (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 wrote a great blog demonstrating how to use it to constrain the I/O a particular process could

The State of the OBIEE11g World as of May 2014

I’m conscious I’ve posted a lot on this blog over the past few months about hot new topics like big data, Hadoop and Oracle Advanced Analytics, and not so much about OBIEE, which traditionally has been the core of Rittman Mead’s business and what we’ve written

Optimizing TimesTen for Exalytics Queries using TimesTen's Index Advisor

Late last week I posted an article on our blog on loading detail-level data into Exalytics; whilst the article was intended really as an introduction to Essbase Aggregate Storage Option, and how it could offer an alternative to TimesTen when storing large amounts of detail-level data, to make the case

TimesTen and OBIEE port conflicts on Exalytics

Introduction Whilst helping a customer set up their Exalytics server the other day I hit an interesting problem. Not interesting as in hey-this-will-cure-cancer, or oooh-big-data-buzzword interesting, or even interesting as in someone-has-had-a-baby, but nonetheless, interesting if you like learning about the internals of the Exalytics stack. The installation we were

Incremental refresh of Exalytics aggregates using native BI Server capabilities

One of the key design features of the Exalytics In-Memory Machine is the use of aggregates (pre-calculated summary data), held in the TimesTen In-Memory database. Out of the box (“OotB”) these aggregates are built through the OBIEE tool, and when the underlying data changes they must be rebuilt from scratch.

Incremental refresh of Exalytics Aggregates using TimesTen

Introduction One of the key reasons that Exalytics can deliver sub-second response times is the use of TimesTen in-memory database to hold data pre-calculated to various levels of aggregation as required by the reports.
