When trying to start the agent, it exits with "System.exit(99) has been invoked" in runner_os_component.log. No other log file is created.
The "System.exit(99) has been invoked'" is most probably because of the unrecognized parameters in the agentparm.txt.
Under 'Additional Jars' in the agentparm.txt, the following parameter may wrap at the end of the line to a new line:
It's possible that some editors may save the lines with a carriage return and result in breaking the classpath and introduce unknown parameters.
To fix this, open the agentparm.txt in vi (UNIX/Linux) or Notepad (Windows). Join the lines; make sure that the classpath includes all the jars.
Save the agentparm.txt and start the agent.
Note: Make sure Word Wrap under Format is not turned in Notepad.
