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.

Note:  

  • 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.
Protocol Description

An acronym for Asynchronous JavaScript and XML. Ajax (Click & Script) uses asynchronous HTTP requests, allowing Web pages to request small bits of information instead of whole pages.
A generic virtual user which uses the standard C library.
A remote access tool, allowing users to run specific applications on external machines.
Component Object Model (COM) - a technology for developing reusable software components.
(DNS) Domain Name Resolution
The DNS protocol is a low-level protocol that allows you to emulate the actions of a user working against a DNS server.
The DNS protocol emulates a user accessing a Domain Name Server to resolve a host name with its IP address. Only replay is supported for this protocol—you need to manually add the functions to your script.
Flex is an application development solution for creating Rich Internet Applications (RIAs) within the enterprise and across the Web. Action Message Format (AMF), is a Macromedia proprietary protocol that allows Flash Remoting binary data to be exchanged between a Flash application and an application server over HTTP.
FTP
(File Transfer 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)
Internet Message Application - a protocol which enables clients to read email from a mail server.
Designed to record java-based applications and applets. It produces a Java language script using web functions. This protocol is distinguished from other Java protocols in that it can record and replay Java remote calls over HTTP.
Common Java recorder.
Java programming language with protocol level support.
(Listing Directory Service)
An Internet protocol designed to allow email applications to look up contact information from a server.
(Microsoft Exchange)
Messaging Application Programming Interface designed to allow applications to send and receive email messages.
MMS
(Media Player)
Streaming data from a media server using Microsoft's MMS protocol.
Important:
  • In order to replay Media Player functions, you must place a file called wmload.asf on the Windows Media server machine. The VuGen machine must be able to access it using mms://<servername>/wmload.asf. This file can be any media file renamed to wmload.asf.

  • Make sure that Media Player is installed on VuGen and the load generator machines.

(Supported for replay only. Support will be discontinued in future versions.)

MMS (Multimedia Messaging Service)

A messaging service used for sending MMS messages between mobile devices.

(Supported for replay only. Support will be discontinued in future versions.)

Mobile Application - HTTP/HTML Enables the recording of mobile native applications.

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.
RDP
(Remote Desktop Protocol)
A remote access tool using the Microsoft Remote Desktop Connection to run applications on an external machine.
(Remote Terminal Emulator)
Emulation of users who submit input to, and receive output from, character-based applications.

Emulation of communication between a browser and SAP server on a GUI or user-action level.

(Supported for replay only. Support will be discontinued in future versions.)
