One of the things that amazes me about Oracle is how active its staff and product groups are in their blogs. In addition to all the traditional technical resources available through the product marketing and support channels, engineers and product managers maintain some amazingly active blogs where they post regularly about:

  • how to address issues that they see customers face,
  • how to do things with Oracle systems that only the super experts would know how to do,
  • and, otherwise provide amazing free educational material for system administrators and developers everywhere.

A notable blog I want to highlight today is "Fore! - Stray shots from Dave Miner." Dave Miner is the architect for Oracle Solaris deployment and system management, has a lot of background in networking on the side. He spends a lot of time operating Oracle Solaris Engineering's OpenStack cloud and is coauthor of the OpenSolaris Bible (Wiley, 2009).

 

Needless to say, he knows his stuff.

 

Earlier this month, he posted about troubleshooting I/O loads in an Oracle Solaris OpenStack Cloud environment that I wanted to highlight by turning it into an official OTN community article here on community.oracle.com.

 

Enjoy!

"The other day we noticed that a number of guests running on our Oracle Solaris OpenStack cloud were very lethargic, with even simple operations like listing boot environments with beadm taking a long time, let alone more complex things like installing packages.  It was easy to rule out CPU load on the compute nodes, as prstat quickly showed me that load averages were not at all high on the compute nodes hosting my guests....[Click Here to Read More]"
