Appendix A - Configuring Local and Agent Computers

After IP Aliasing is set up, open a suite, click

Suite > Edit

Runtime

, and then select the

Enable IP Aliasing

check box.

If IP Aliasing is selected in the suite, at the beginning of a run, the TestManager
software on each computer (Local or Agent) queries the system for all available IP
addresses. Each suite scheduled to run on that computer is assigned an IP address
from that list, in round-robin fashion. If a computer has more virtual testers than IP
addresses, an IP address is assigned to multiple virtual testers. If a computer has
fewer virtual testers than IP addresses, some IP addresses are not used. This approach
optimizes the distribution of IP addresses regardless of the number of virtual testers
scheduled on a computer and frees you from having to match IP addresses to specific
virtual testers.

Assigning Values to System Environment Variables

TestManager passes the system environment variables set on an Agent computer to
each virtual tester. If you are using virtual testers to test a database server or
application, you can override these system environment variables.

To override the value of a system environment variable:

Click

Suite > Edit Settings

, and then click in the

Sys Environment Variables

column

of the User Settings dialog box.

You can change the value or a previously set system environment variable in the
System Environment Variables dialog box. For more information, see the TestManager
Help.
