With the 12C version oracle come with many amazing feature, one of them is the integration of ORACLE database with the awesome dynamic tracing framework DTRACE on SOLARIS system.In fact we can see this in action using V$KERNEL_IO_OUTLIER view.Like explained by Andrey Nikolaev in https://andreynikolaev.wordpress.com/2013/09/20/vkernel_io_outlier/ this view is based on a DTrace script running in the background.He also managed to rewrite the script so it can be used also on pre-12c Oracle databases.(That’s cool !!)
But what About Linux system ?
