Test tools

To facilitate the placement and management of simulated loads on an HP SBC server, HP used

Terminal Services Scalability Planning Tools (TSScaling), a suite of tools developed by Microsoft to
help organizations with Microsoft Windows® Server 2003 Terminal Server capacity planning.
Table 1 describes these tools.

. Components of TSScaling

Component Description

Automation tools

Robosrv.exe

Drives the server-side of the load simulation

Robocli.exe

Helps drive the client-side of the load simulation

Test tools

Qidle.exe

Determines if any scripts have failed and require
operator intervention

Tbscript.exe

A script interpreter that helps drive the client-side load
simulation
