Record the Script: Usually, this is the first step of scripting where every user action is recorded into a script. Replay and Verify: Once the script is recorded, reply the script to ensure its working right. Verify any impact through application frontend or database. Enhance the Script: Once recording has been verified, enhance script by adding checkpoints, validating data, adding transactions and rendezvous points. Replay and Verify: As earlier, re-play your script and verify that everything is working as intended. Configure Runtime Settings: Configure and control pacing duration, think time variation, proxy settings and whether you wish to ignore any external resources.

VuGen can also run scripts for debugging. LoadRunner can record scripts in both single and multi-protocol modes. For some protocols, various recording modes are available to further refine the resulting script. This is called parameterization. Dynamic content refers to page components that are dynamically created during the execution of a business process, and the value may differ from the value generated in a previous run. Examples of dynamic content include the ticket number in an on-line reservation system, a transaction ID in an on-line banking application and most importantly the unique session ID that is created each time a user logs in.

Such dynamic values must be correlated in order to run the recorded script. The script while running will return an error if such a dynamic value has not been correlated, since the value changes each time the user logs in. If the dynamic content is a part of a previous server response, LoadRunner can correlate that value with future instances in which it must be sent back to the server.

HP LoadRunner saves the changing values into parameters, which are used during simulation. During a scenario run, the Controller allows monitoring of network and server resources.

The Controller assigns virtual users and load generators to specific scenarios. To run a test of users, three or more machines can be set up with an HP LoadRunner agent installed on them. These machines are known as load generators because the actual load is generated from them. Each run is configured with a scenario that describes which scripts will run, when they will run, how many virtual users will run, and which load generators will be used for each script. The tester connects each script in the scenario to the name of a machine that is going to act as a load generator and sets the number of virtual users to be run from that load generator.

This is called the working in HP load runner. The software is intended for performance testing for businesses of any size. This runs GACSetup. However, the folder created after an English language install is MB. Version 8. It adds "Additional Attributes" to Runtime Settings. It separates SQL time in execute, parse, and fetch times. Version 7. Version 6. Every VUser utilised a single operating system thread, while 50 VUsers ran in a single process by default.
