The single most important piece of information processed by top is the measure of a process's percentage cpu utilization, known as percent cpu. Although top is perfectly capable of display and sorting on a variety of information, by default it sorts by percent cpu. The reason for this is that most people use top to find out what the cpu is doing, or more specifically which process is hogging the cpu. Percent cpu readily reveals this information.

When someone at a conference discovered that I was the original author for the utility "top" the reaction is always the same: "hey that's a really cool program", "thanks for writing it", or "top really saved the day". I am glad that in my own little way I was able to contribute to the system administrator's toolbox. But for years I have been unable to do much additional work with top, and it has become rather out of date. I was able to keep up with some of the operating system changes, but I have not really been able to add useful features to it or to track the seemingly endless variations that others have implemented.

Solved -- The box didn't retain my permissiable SELinux environment after a yum update. With a 'sudo setsebool -P samba_enable_home_dirs=1' there was a mighty noise and it started allowing public read-only access to the share.

Someone liked my work (that they help me do) so well, that recently they requested I share the file with everyone on the LAN. I set out to create a publicly readable Samba share for the file. As a user, I issued a 'sudo yum install samba' and soon after started working on the default config file in /etc/samba/smb.conf.

Here's the mix I came up with (which, keep in mind, doesn't work; I could use some help!)

Well, I didn't expect it to take this long to get to the point of making this blog entry. Busy-ness is happy-ness, or something schmarmy like that...

So, I had this Oracle database with 9 independant tablespaces - each one for a different library in this case. The challenge, I am moving them all to a new install on a new server, but not all at once. And, after I migrate one, I 'upgrade' the application running on it. It's been fun. What I've found about tablespace migrations...

I've got two methods of doing it really. The first one is the one I like better at this point, though it's not the one recommended by the vendor. It seems to work just as well though. Basically, their tablespaces are independent enough that they're "Transportable". I.e. I can transport one tablespace, and run the upgrade process which cleans up some Invalid objects, and at the end it's just as good.

Sysadmin's Basic Guide to SSL Certificates and Authorities

Intended audience: system administrators who know roughly what SSL/TLS is and can use SSH and OpenPGP products (such as GnuPG) and who now want to know more and perhaps issue local certificates. You should know what public-key cryptography is, but are not expected to be able to follow any math (no equations herein) -- this is about using the stuff, not understanding the underlaying principles. You understand that "encrypt" is scrambling and "decrypt" is descrambling.
