The Agent is launched via the agent.bat/.sh file within the installation/extracted directory. This can be accessed directly through your file explorer or via a command prompt/terminal.
An example of a terminal command would be:
java Xmx512m jar "C:\Program Files\T-Plan\RAP\robot-rap-agent.jar" %1 %2 %3 %4 %5 %6 %7 %8 %9
Once the Agent has been launched, and the appropriate configuration values entered (See: Setting up the RAP Agent) you can then start it by selecting the "Start" button.
Once the Agent is running, it will report its current status and version:
In addition, the Agent Name field becomes available to edit:
This will default to "RAP Agent - <pcName>" however it can be edited at any time to a name of your choice. Selecting the Save icon will apply the change which will also be reflected within the RAP UI upon the next Agent poll interval.
