A few years ago, one of the companies I worked with created a "Production Application Support Team", or PAST.  These were the sysadmins and programmers intended as the next line of support after the helpdesk, who could triage some problems and perhaps actually fix them. The team had a problem - vague complaints that the website was "slow" for login.  Yet anytime a leader got the phone call, they would give the site a try, and see reasonable response times.  PAST had a motivated programmer on Read more [...]

If you’ve used done any performance testing, or even seen a demo, you are probably familiar with the “big line graph” that is created as the test runs. The typical scenario is simple:  Have the load tool start with one simultaneous user running a script.  Then add a new user, say, every thirty seconds plus a small random pause.  The script consists of a set of pre-defined operations - login, search, click on some item, and logout. As more users are added we expect to see response Read more [...]

Many of our clients have enterprise applications that are accessed 24 hours a day, seven days a week.  Their applications may be accessed remotely from all over the world.  In such cases, total users could number in the thousands. When configuring a test plan for our clients we want to establish a realistic number of concurrent users, in other words, the number of users actually in the system, actively using the application at a given time. Recognizing the difference between total users and Read more [...]

Steve Sutphin, an Oracle expert for over 20 years, had this to say about using AppLoader for regression testing. One of the universal facts with Oracle E-Business Suite or any other large software package is that you eventually will need to apply patches. The Oracle E-Business Suite patches vary in size and scope. From the small one-off patches (also called an Emergency Patch) to a large upgrade patch, you will need to determine two things. First, did the patch fix the problem and second did the Read more [...]

Testing Java application to uncover Java Virtual Memory - JVMs compatibility: Often problems with JVMs are related to incompatible configurations or versions with the application that uses the JVM or the environment for which the JVM is running. You might be facing a problem where you are using a Java Applet application that utilizes a JVM to launch. Remember that whenever you upgrade your application’s backend Java code, in some cases, you need to also upgrade the JVM on the front end or make Read more [...]

1 – Test from the end user’s perspective The first objective of a successful load test is not to lose focus of the most important metric of the test; The End user’s experience with the application. Remember that an application server, a network, database, etc. might perform well under heavy load, but your tests are not conclusive if they don’t replicate real world transactions executed the same way the end users will. 2- Set test objectives Define the test objective for response time and Read more [...]
