In “Part 1: How To Load Test OAM11g using Apache JMeter” I talked about an example plan that could be used to load test OAM11g, which included some common configuration elements, some samplers for login, authorization, logout, and some listeners that provided result analysis. In Part 2, I wanted to expand on an option to make JMeter send random logins and I will explain why, and then cover how to leverage JMeter to load test an LDAP server like OUD, OID, ODSE, or OVD.
The Maven Release plugin can be used to release a project using Maven. Normally, a release can be made in two simple steps: prepare en perform. When the Mercurial SCM (Source Code Management) is used, this process requires a little more configuration. I performed the described steps using Hg (Mercurial) version 2.0.2 and maven-release-plugin version 2.4.2 on a Ubuntu 12.04 VM. The used distribution servers are Nexus 2.2-01 instances.
It’s almost two years now I joined the Rittman Mead team and never wrote on this blog before, time to start. For this first post nothing long, I wanted to share something I had to setup few weeks ago on a project and it can be interesting for others as well.
If you read the Oracle Documentation for Oracle BIA (126.96.36.199), you could find the following; “Currency conversions are required because your business might have transactions involving multiple currencies. To create a meaningful report, you have to use a common currency.” Oracle BIA stores amounts in the following currencies; - Document Currency –> Currency of the […]
At my current assignment, I’ve gone to great lengths to improve the Oracle SOA Enterprise Manager Console performance. One of the actions I took, was purging about 700 gigabytes of data from the dehydration store. Although that solved lots of other problems, the EM still wasn’t very responsive. Loading composite details could take op to 20 minutes, it they ever loaded at all. Apparently, the database was ok, because there was no load at all there. The java processes used a lot of CPU and memory though.
A little while ago, Antoine Girbal wrote a great blog entry describing how to speed up a MonogDB MapReduce job by 20x. Now that MongoDB version 2.6 is nearly upon us, and prompted by an idea from one of my very smart colleagues, John Page, I thought I'd investigate whether MongoDB Aggregation jobs can be sped up using a similar approach. Here, I will summarise the findings from my investigation.
While working with a client this week, I came across an interesting issue, and ultimately a workaround, when patching Oracle Data Integrator 12c. But first, a little background…

In the second part of the series we cover:
More discussion on ODI vs Informatica
More on migrating from OWB to ODI
Using ODI outside the data warehouse (BI Apps)
ODI in the cloud
ODI and Big Data
The Big Data presentation I gave yesterday is now available for download. In this presentation I define some common features of Big Data use cases, explain what the big deal about Big Data is all about and explore the impact of Big Data on the traditional data warehouse framework.
