VuGen Protocols

VuGen enables you to record a variety of protocols, each suited to a particular load testing environment or topology and resulting in a specific type of Vuser script. For example, you can use a Web - HTTP/HTML Vuser Script to emulate users operating Web browsers. You can use FTP Vusers to emulate an FTP session. The various Vuser technologies can be used alone or together to create effective load tests.

The following table lists the available Vuser protocols, and a brief description of each protocol.


  • Protocols with links have expanded information.
  • When running tests using protocol-specific Vuser scripts, make sure you have a global license or the required license for your protocol.

The FTP protocol is a low-level protocol that allows you to emulate the actions of a user working against an FTP server.
(Internet Messaging)

Web - HTTP/HTML (for mobile applications) Enables the recording of mobile native applications.
MQTT Enables lightweight, publish/subscribe messaging that is ideal for Internet of Things (IoT) and machine-to-machine (M2M) communications, as well as mobile applications where bandwidth and battery power are at a premium.
Open Database Connectivity - a protocol providing a common interface for accessing databases.
Oracle database using a standard 2-tier client/server architecture.
Oracle - Web
The Oracle Applications interface that performs actions over the Web. This Vuser type detects actions on both the API and Javascript levels.
Oracle 3-tier architecture database consisting of Java client, Web server and database.
(Post Office Protocol)
A protocol designed to allow single computers to retrieve email from a mail server.
(Remote Desktop Protocol)
A remote access tool using the Microsoft Remote Desktop Connection to run applications on an external machine.
