Because Database Vusers are not reliant on client software, you can use Database
Vusers to test server performance even before the client software has been
developed. Further, because Database Vusers do not have a user interface,
system resources are not used, and you can therefore run large numbers of
Database Vusers on a single workstation.
The following example illustrates the use of Database Vusers: Suppose that you
have a database server that maintains your customer information. The information
is accessed by numerous customer service personnel who are located throughout
the country. The database server receives the queries, processes the requests,
and returns responses to field personnel.
You want to test the response times of the server when numerous service
personnel simultaneously access the server. Using LoadRunner, you could create
several hundred Database Vusers, each Vuser accessing the server database. The
Database Vusers enable you to emulate and measure the performance of your
server under the load of many users.
You develop a Database Vuser script to define the actions of a Database Vuser. A
Database Vuser script includes functions that control the script execution, specify
the input that the Vuser submits to the server, and measure the server
performance.
You develop Database Vuser scripts either by recording with LoadRunner's Vuser
Script Generator (VuGen) or by using LoadRunner's Vuser script templates.
