Part 2: Advanced Apache JMeter Stress Testing OAM and LDAP

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.

Using the Maven Release plugin with Mercurial SCM

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.

Tweaking the entropy pool for a better SOA performance

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.

How to speed up MongoDB Aggregation using Parallelisation

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.
