20 Mar 2014 04:00:00 +0000This tutorial creates a Rails version of old green screen Start SQL Interactive Session (STRSQL) utility. Most IBM i professionals use STRSQL on IBM i, but if you have not, simply sign on to your IBM i 5250 and enter STRSQL on the command line. Other products duplicate the STRSQL support as a client/server application, but this Rails version stays completely on the IBM i server and use any device with a browser as the interface.

26 Mar 2013 04:00:00 +0000IBM® Power Systems™ firmware update, which is often referred to as Change Licensed Internal Code (LIC) procedure, is usually performed on the managed systems from the Hardware Management Console (HMC). Firmware update includes the latest fixes and new features. We can use the Change Licensed Internal Code wizard from the HMC graphical user interface (GUI) to apply updates to the Licensed Internal Code (LIC) on the selected managed system. We can select multiple managed systems to be updated simultaneously. The wizard also allows us to view the current system information or perform advanced operations. This tutorial provides the step-by-step procedure for the IBM Power Systems firmware update from the HMC command line, and the HMC GUI and is targeted for system administrators. This step-by-step instructions can prepare the newbie for what needs to be done and how it could be done to stay on to the latest firmware level all the time. When you purchase a new hardware, the best practise is to upgrade all the firmware to the latest level.

07 Oct 2008 04:00:00 +0000To leverage round-the-clock computing, tasks must run at all hours of the day. You could punctuate your sleep with waking interludes to log in and run this command or that command on dozens of machines, or you can enjoy your forty winks and turn the work over to the ubiquitous cron, a daemon, or perennial process, to execute commands on a schedule. From very often to every so often, cron happily minds the clock and runs jobs day or night. Learn how to configure and maintain cron, and discover just some of its many uses.

20 Feb 2007 05:00:00 +0000When writing a shell program, you often come across some special situation that you'd like to handle automatically. This tutorial includes examples of such situations from small Bourne shell scripts. These situations include base conversion from one string to another (decimal to hex, hex to decimal, decimal to octal, and so on), reading the keyboard while in a piped loop, subshell execution, inline input, executing a command once for each file in a directory, and multiple ways to construct a continuous loop. Part 4 of this series wraps up with a collection of shell one-liners that perform useful functions.
07 Nov 2006 05:00:00 +0000The vi text editor might seem counterintuitive to new users but, make no mistake, there is a good reason this 30-year old tool is still widely used by many of the best developers in the world. The vi text editor separates operations into insert mode and command mode, which gives you ultrafast access to key commands that can edit, insert, and move text in on-the-fly, user-defined segments.
26 Sep 2006 04:00:00 +0000Systems administrators can use a number of programs to maintain files in a UNIX(R) system from the command line. In this tutorial, you'll experiment with commands, such as cd, cp, and tar, to navigate a UNIX file system from the command line and work with files and directories. The cd command changes directories, cp duplicates files or directories, and tar quickly groups files into an archive. You'll also learn how to deal with file permissions and perform simple input/output.
31 May 2006 04:00:00 +0000Examine the processes behind building a parser using the lex/flex and yacc/bison tools, first to build a simple calculator and then delve into how you can adopt the same principles for text parsing. Parsing text -- that is, understanding and extracting the key parts of the text -- is an important part of many applications. Within UNIX(R), many elements of the operating system rely on parsing text, from the shell you use to interact with the system, through to common tools and commands like awk or Perl, right through to the C compiler you use to build software and applications.
