Parameter: disableXrs

Startup parameters change the behavior of the Service Manager server. You can always set a startup parameter from the server's operating system command prompt.




The Service Manager process creates a JVM and provides default option of -Xrs on startup to reduce the signals to be handled by the JVM. However, you may want to generate thread dumps for debugging purposes, and then you would want the JVM to receive these signals. Use the -disableXrs parameter in sm.ini, so that the Service Manager process will not provide this option to JVM.


  • This parameter is honored only in Windows environment for debugging purposes.
  • If you use Remote Desktop and start a Service Manager process using disableXrs:1, and then close the session or log off, the Service Manager process will be shutdown.
