Successfully launched a test JVM with the memory setting of '768'. Note that this does not guarantee that IBM Cognos 8 will start and run successfully.
To see which JVM options are based on this setting, view c8_location/bin/bootstrap_<OS>.xml and see your JVM documentation for an explanation of those options.
Since the value is empty, the feature is disabled. There is nothing to test.
