  • Cloud computing

    Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.
    Cloud computing can be confused with:

    1. grid computing—”a form of distributed computing whereby a ‘super and virtual computer’ is composed of a cluster of networked, loosely coupled computers, acting in concert to perform very large tasks”;
    2. utility computing—the “packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility such as electricity”;
    3. autonomic computing—”computer systems capable of self-management”.
  • MySQL Table Maintenance.

    This morning I was asked by one of the other Engineers in my group about an easy way to analyze all the tables in a database. So I pointed him to mysqlcheck. Which is a great command line client for performing table mainteneance on mysql database tables. It checks, repairs, optimizes, or analyzes tables, all from the command line. Like any other program it has a ton of flags, but here are three general ways to invoke it.

    shell> mysqlcheck [options] db_name [tables]
    shell> mysqlcheck [options] –databases db_name1 [db_name2 db_name3…]
    shell> mysqlcheck [options] –all-databases

  • Unfreezing media in Netbackup on Solaris.

    Here is something you don’t use everyday or at least I don’t. 🙂

    First find the frozen media IDs.

    shell>/usr/openv/netbackup/bin/goodies/available_media | grep FROZEN

    A00060  HCART3   TLD      1       37     –       1     0        FROZEN
    –snip–

    Then unfreeze them with this command xenical otc.

    shell> /usr/openv/netbackup/bin/admincmd/bpmedia -unfreeze -m A00060

  • Configuring YUM to use a Proxy Server.

    There are two basic ways that you can configure YUM to use a proxy server.

    First is by editing the yum.conf file pop over to this web-site. The yum.conf is usually localed in the /etc directory. You will need to add couple of parameters depending on your proxy configuration.

    1.) The first parameter is to add the proxy server to the yum.conf.

    # The proxy server – proxy server:port number
    proxy=http://yum.proxy.server:3128

    2.) Now If a username and password is required to login to the proxy server.

    # The account details for yum connections
    proxy_username=username
    proxy_password=password

    The second way is by configuring the user’s environmental variables.

    1.) The first way is just by adding the proxy server information.

    bash> http_proxy=”http://yum.proxy.server:3128″
    bash> export http_proxy

    2.) The second way is by adding the proxy server with an username and password.

    bash> http_proxy=”http://username:password@yum.proxy.server:3128″
    bash> export http_proxy

     

  • My First Post

    So here’s the story; I’m horrible at grammar, spelling and pretty much anything else to do with the English language, but I decided to start a blog anyway. Foolish human.. 🙂

    This will be a pretty boring blog to most of you since it will be a technical blog, with a few rants from yours truly. So, if you are a geek or a nerd, great, if not, go herehttp://www.life.com, a great site I helped build.
