In recent years, Db2 for i Business Architect Scott Forstie and his team have rapidly strengthened the IBM i database, improving the sophistication of its SQL query engine, and adding to its galaxy of IBM i services. What’s more, they have several years’ worth of new enhancements in the pipeline.

CIOs and IT Directors can meet Scott at the CIO Summit on March 25, 2019, Charlotte, North Carolina, for an IBM i strategy briefing.

Collaboration at COMMON

The 2015 COMMON annual meeting and expo, now in its first day, is helping speakers and attendees create innovation through IBM i integration: open source, closed source, IBM and vendor solutions. For example, of my six presentations during this conference, two are collaborations:

The Art of Performance Diagnostics, with IBM’s Dawn May, allows us to show, among other topics, how IBM i’s integrated performance tools complement green-screen tools and third-party tools (in this case, Zend Server) to pinpoint and solve performance issues (here, PHP-and DB2-based applications).

PHP Tricks for RPG Developers, a talk jointly created by RPG and SQL expert Birgitta Hauser and me, combines RPG, PHP, and DB2, allowing RPG to achieve graphical (charts and graphs, PDF and Excel files) and internet (json-based web services, flexible email) functionality using native functions.

Conferences such as COMMON serve a need that’s difficult to replicate back at the office—brainstorming and sharing possibilities among interdisciplinary peers, or sitting side-by-side with like-minded colleagues who work for different employers, to try something new. This week, for example, some of us plan to share knowledge on compiling binaries in PASE and to further the potential of open source on IBM i. I’m looking forward to presenting my talks (both joint and solo) and helping to realize new ideas with forward-looking colleagues during the conference.

Free PHP still exists on IBM i (Zend Server Basic Edition)

I’ve been hearing from people confused about Zend Server editions on IBM i. Yes,  Community Edition was removed with Zend Server 7/8, but Zend replaced that with the no-charge “Basic” edition. The Basic edition exists only on IBM i. It requires registration but at no cost. Zend Server for IBM i can be downloaded here.

While I often recommend the Professional or Enterprise editions of Zend Server for the value-added tools and for Zend’s professional support, rest assured that free PHP still exists, with the Basic edition.

For more information, here is the current list of Zend Server editions for IBM i.

[Update: See PHP 7 and Free Basic Zend Server Edition for IBM i ]

Zend Framework 2 performance optimization: it works

Zend Framework 2 (ZF2) provides optimization techniques that are often overlooked by published performance tests. One excellent source for such techniques is a presentation by Gary Hockin. I was thrilled when my client and friend King Harrison IV of K3S began testing the effect of these techniques on his ZF2 application running on IBM i.

King’s initial tests produced a 600ms reduction in load time, obtaining respectable performance for his database-heavy application. He plans to update his blog post with further speed improvements as he implements them.

Read King Harrison IV’s blog post about ZF2 performance improvements.

Save your fingers when using PHP-CLI

In Batch PHP I showed how to call PHP from a command line. For example, with Zend Server 6 or 7 on IBM i, one would launch a PASE command line using the command CALL QP2TERM, or launch QShell using QSH, then type a command such as this:

/usr/local/zendsvr6/bin/php-cli myscript.php

For those of us who use PHP-CLI often, the above command can be a finger-buster. Let’s shorten the path by creating a symbolic link:

cd /usr/bin
ln -s /usr/local/zendsvr6/bin/php-cli phpc

I created the symbolic link in /usr/bin, a directory that is likely to be in any user’s path.

Now try the shortened command:

phpc myscript.php

To test the shortcut without a PHP script, use the -v switch, which requests version information (‘v’ for version) about your PHP installation.

phpc -v

The above command will return version information that starts out something like this:

By creating a symbolic link to the PHP-CLI binary, practitioners of PHP can speed their work while saving their fingers.
