Following our previous post on planning a load test, we are throwing in more points that you should consider when planning for a load test. Read the rest of this entry »
Before we are able to analyze and determine tuning areas, we need to understand Oracle Server Architecture and it’s underlying mechanism. Oracle Server Architecture consist of two main categories: logical (memory) structures and physical (or file) structures. The Oracle memory structure is collectively known as Oracle Instance. While the physical file structures are collectively known as Oracle database. Together, they are call an Oracle Server. Read the rest of this entry »
Let’s touch on the monitoring implementation model for now. A new topic that was not covered in the predecessor site. You will benefit in understanding how to implement the the monitors in the testing environment as well as provide the requirements to the network and server teams to set the monitoring. In this article, we will be omitting the details of SiteScope and Diagnostics integration and the implementation for the moment and they will be discussed in future post! So stay tuned for that!

Hit on the spot! An interview question for newbies! Yes, we can load test a 3-tier architecture using LoadRunner. This is the purpose of the product. Usually in a 3-tier architecture, there will be one point of contact by the real user, the URL address of the web application. This is where LoadRunner access the web application too.

Points to note prior or during the scenario execution. This will save you unnecessary trouble looking at logs and reconfiguring the environment
1. First, ensure the environment for load testing is consistent for all participating machines (ie. Controller and Load Generators). As the scripts are sent to the Load Generator to be executed, it must have the same environmental settings of the recorded scripts (in VuGen). For example, if the script was recorded in RMI-Java, JDK 1.4 exists on the machine that performed the recording. In the same context, the Load Generator will also require the JDK 1.4 to be installed on it for the script to execute properly. Therefore, ensure JDK versions are installed and similar to the recording machine. Read the rest of this entry »
