Installing Zend Server on the i: How and Why PDF Print E-mail

Want to get started with PHP on the i? Well, the first step is to download the products that are available on the i from Zend. And the first part of that is to download the Zend Server. But how? And why?

david shireyWritten by David Shirey

PHP on the i. Why am I bothering to write about this? Mostly because I think we have reached a point where every RPGer and every IBM i should have some capability to do web-oriented languages. You might use Ruby or CGIDEV or even Java, but I'm a PHP fan. You might decide to learn PHP yourself and build your own scripts, or you might find real PHP programmers and have them do the work for you. What's important is that unlike a web PHP app, which can be done on your PC, PHP apps that run on the i and interface with the DB2 database on the i, are going to need a development and run environment that runs on the i itself. And the best option for that is Zend Server. But many people have an ancestral fear of words that begin with "Z," so a little encouragement may help.

Technology Focus: Finding What Shouldn't Be Broken with Software Testing Tools PDF Print E-mail
Programming - General

Bugs in software can be due as much to organizational problems as bad coding. Finding errors reliably often requires some help.

john gristWritten by John Ghrist

When you stop and consider how complex some of today's software applications can be, it can seem like a minor miracle that they work as advertised. As we all know though, applications often don't do what they're supposed to do or don't do it the right way. When that happens, software testing tools and methodologies can be an important remedy.

Here's an alternative to data queues that works especially well when your primary input is a database file.

joe plutaWritten by Joe Pluta

I've written two articles on how to use data queues. Data queues are especially practical when you're sending many messages with different layouts between multiple clients and servers. They're easy to create and don't require much in the way of initial design. Simply create the data queue and away you go!

The Transfer Ownership (XFRO) MI Instruction PDF Print E-mail

Wednesday, 03 September 2014 00:00

Investigate the XFRO MI instruction by experimentation.

junlei liWritten by Junlei Li

According to the MI documentation in the IBM Knowledge Center, one of the reasons that may cause the Object Not Eligible for Operation (hex 2204) exception is a temporary object was referenced on a Transfer Ownership instruction. The Transfer Ownership (XFRO) MI instruction, which has been available since System/38, transfers the ownership of a permanent MI object from its original owning user profile to another user profile. This article discusses the functionality of the XFRO MI instruction and the use of this MI instruction by the operating system.
