In this blog, I am going to demonstrate how we can use the wait event category sqlos.wait_info* to track the wait resources the queries running in a particular session undergo.
My colleages and I want to set up a LAN radio station, so that we can all groove to the same soundtrack. To make things interesting, we want to be able to dynamically add songs to the playlist. From any machine. And since I don’t really have time to do something like that, I’m setting myself a deadline of one evening to get it running. Got it? Good. For it’s time to rip our shirts.

While Oracle does supply a list of RPMs that must be installed on a Linux system, that information does not help you in determining which Oracle files are dependent on the RPMs in question. If the list of RPMs to be updated is small, it may even be that that few, if any of the Oracle files on a server may be affected. Here’s how that can be determined.
If you do any performance tuning , and everyone does, then you’ll come to a point where you want to know if your tables have sufficient indexes to serve the queries fast, here’s how.
