Just like with the old JRockit Runtime Analyzer, it is possible to start up recordings using command line parameters to JRockit. The parameter is called -XX:StartFlightRecording in R28.
Below is an example that starts a flight recording half a minute after the JVM has been started. The recording will last for a minute. The name when viewing the ongoing recordings will be MyRecording, and the resulting file will be written to C:\tmp\myrecording.jfr. The recording will use the settings in jre\lib\jfr\profile.jfs.
-XX:StartFlightRecording=delay=30s,duration=60s,name=MyRecording,filename=C:\tmp\myrecording.jfr,settings=profile
For more information, see the JRockit R28 command line parameter documentation.
