Running More Than 1000 Virtual Testers

Appendix A - Configuring Local and Agent Computers

For example, if using the test machine as an agent, set up the SharedSection value
for 2,000 virtual testers as follows:

SharedSection=1024,10000,512

Reboot the system for changes to take effect.

Increasing desktop heap can allow an ill-behaving application to consume more
resources than desired. While increasing heap will allow more virtual testers to run, it
also decreases the number of desktops that can be created. These values should only
be increased by an amount sufficient to run the number of virtual testers desired.

Running More Than 24 Virtual Testers on a UNIX Agent

If your suite runs more than 24 virtual testers on a UNIX Agent computer, you must
set the following system environment variables:

zzzz

The third value applies to non-interactive desktop heap. If this parameter is
missing from your registry, the default value will be 512K.

If you are running Rational Test Agent as a service, do not modify
system-wide desktop heap. Instead modify this non-interactive desktop heap
value, setting it to an amount appropriate for the number of virtual testers you
are running. Allow for approximately 5K per virtual tester for Windows NT
and Windows 2000, and 10K per virtual tester for Windows XP.
