PHP doesn't run in RSE or PDM, so how do you set up scripts (not programs) or do your testing? Do you need a PC? Or can you do it from the i?

david shireyWritten by David Shirey

RPG runs natively on the i. You create your program in a source file using PDM or RSE and then compile. Everything that RPG needs to do its thing is already built into the IBM i. PHP isn't like that. You need to do a little bit of work to get it to function.

 

I know you'd prefer to just dive into things. But you can't do that with PHP on the i because some effort is required to get it to work. So pay attention: this is important stuff.

In the fall of 2014, IBM introduced the Node.js platform to IBM i. Learn what it is and what you can do with it.

aaron bartellWritten by Aaron Bartell

Right now is a very exciting time for open source on IBM i. Not only have a number of new technologies like Ruby and Node.js garnered formal ports to the machine, there are also hints of what's coming next from IBM on their developerWorks sitein particular, Python, gcc, and Git. Each of these has already been made to work on IBM i by way of perzl.org, but now IBM is making them additions to the new 5733OPS licensed program, which means they are fully supported. That's a big deal because it conveys intent and direction!

TechTip: The Many Dimensions of SQL DEFAULT Values PDF Print E-mail

Learn how using DEFAULTs in DB2 for i SQL can improve code management.

Written by Michael Sansoterra

With respect to computer systems, Dictionary.reference.com defines a "default" as:

value that a program or operating system assumes, or a course of action that a program or operating system will take, when the user or programmer specifies no overriding value or action.

 

Defaults are useful because they represent a common, standard value or processing action to take unless an alternative value or action is needed. Using defaults in DB2 for i can simplify development because developers can insert common, valid data, into table columns without necessarily having to concern themselves with "what value" is required.

Using the ibm_db gem, we can easily communicate with DB2 for i directory from Ruby.

aaron bartellWritten by Aaron Bartell

In the article "Sinatra Sings, Ruby Plays," I introduced the Sinatra web framework , and we went through initial installation and a simple Hello World application. In this article, we will take that app further by introducing database access. Specifically, we will use the ibm_db gem to query a DB2 table named USERS and display the contents back to the web page.

Partner TechTip: Coming to Grips with QZDASOINIT Jobs PDF Print E-mail

What is the true nature of database server jobs, and how can we keep them from running wild in the system?

kurt thomas.Written by Kurt Thomas

When an IBM i environment experiences rapid CPU consumption or other conditions that impact memory, there are some jobs that will make the list of usual suspects more often than not. While QZDASOINIT jobs almost always make the lineup, they're rarely solely to blame. More often, they're only guilty by association.

TechTip: Getting off the Ground with PHP PDF Print E-mail

PHP is a serious contender for "best bet" for developing robust web applications on the IBM i, but how much do we know about it? Or, more appropriately, how much do you know about it?

david shireyWritten by David Shirey

This is going to be the start of a series, a series on PHP. And that certainly seems appropriate as PHP is one of a number of ways to do web applications from the i. And from my point of view, it's one of the best ways. But unfortunately, it still remains pretty much one of the best-kept secrets in the i world for many of us.

The current breach epidemic could impact IBM i, but it doesn't have to.

robin tatamWritten by Robin Tatam

Unless you're filing your taxes with an address listed as "under a rock," you're probably painfully aware of a few high-profile data breaches that have occurred in recent years. While Target, Home Depot, and Anthem might not openly share whether any of their compromised systems included IBM Power Servers, we all need to learn numerous lessons, regardless of the technology platform our critical data resides upon.
