KB10887: How to turn on the Verbose Garbage collection logging for the Java Virtual Machine

Follow these steps to enable verbose garbace collect (GC) logging:

• Add -verbose:gc to the OtherOptions value in the following location in the registry:
  

  
  HKEY_LOCAL_MACHINE\SOFTWARE\Strategy\JNI Bridge\Configuration\JVM Options

  
  OtherOptions is designed to be a semicolon-separated list of JVM start-up options. Therefore, if there is more than one option, the value would appear like "

  -Xrs;-verbose:gc

  ".
  
• Restart IIS.
• Open a debug monitor application, such as DebugView. DebugView is an application that allows users to monitor debug output on the local system, or any computer on the network that can be reached via TCP/IP. It is capable of displaying both kernel-mode and Win32 debug output, so a debugger isn't necessary to catch the debug output the applications or device drivers generate, nor do the applications or drivers require modification to use non-standard debug output APIs. The Strategy components have configured the JVM to send -verbose output to the debug monitor.
• Connect to Strategy Web and begin using the web application. -verbose:gc output should appear in the debug monitor when garbage collections occur. If it does not, ensure that the user context under which the virtual directory is running has permissions to output to the debug monitor.
