Library Note Morgan's Library Page Header
Coming to OpenWorld 2018? Be sure to visit the TidalScale booth in Moscone South and learn how to solve performance problems and lower costs with Software Defined Servers. Before you visit the booth, or if you can't make it this year, check out TidalScale at www.tidalscale.com. Be sure to click on the Solutions link and look through the Oracle resources.
Purpose The entries on this page demonstrate ways, from within the Oracle database, to access information about the host hardware and operating system. There are ways to do it in the operating system shell environment but what is important, most often, is to see what the database has access to and what Oracle will be watching for licensing purposes.
