Zendcon 2014 promo video for IBM i users

About Zendcon:

ZendCon+Tutorial discount expires Aug. 31

ZendCon, the premier PHP conference, October 27-30, 2014, in Santa Clara, California, has a discount expiring August 15 31 (extended!). When you register, be sure to include the tutorial day (Oct. 27). If you already registered but forgot to add the tutorial day, you can contact the organizers via a link at the bottom of the registration page. Among other half-day tutorials, I’ll be presenting two focused on IBM i:

  • PHP Performance on IBM i
    • If you’re interested in performance of PHP, or IBM i generally, in order to scale your application up to meet increased user demand, or if you have specific performance needs right now, you’ll want to attend.
    • Additional insight to be provided by IBM’er Tony Cairns (see below)
    • Testimonial from last year: “Our process now runs 30-50% faster, thanks to one tip from Alan’s presentation.”
      —Mike Meszaros, Software Developer, Specialty Pipe & Tube
  • DB2 with PHP in Depth
    • DB2 on IBM i has received major enhancements over the past year, including a dozen new settings in the PHP ibm_db2 middleware. Hear  how they can help improve security, performance, and stability. Other topics will include, but not be limited to:
      • Basic topics (with added commentary to make it interesting for everyone) such as library lists, prepared queries for security, persistent connections
      • DB2 in frameworks
        • Zend Framework 2
          • Including pagination (page-at-a-time logic)
        • Status of PDO and how it can be used in Laravel and other frameworks
      • The real scoop about modernization and the DDS vs. DDL (SQL) debate
      • Connecting to IBM i’s DB2 from Windows and Linux and other IBM i partitions
      • How to link MySQL-based applications (WordPress, etc.) to DB2 with the DB2 Storage Engine, with special tips
      • Using DB2’s HTTP features to make PHP-based web services even more accessible, including to allow RPG to call PHP and get results back
      • How to optimize queries
      • Strategies to safely open your application to the public
      • Topics and questions that YOU request (contact me in advance if you wish)

My co-presenter for tutorials will be IBM’s Tony Cairns, who helped bring PHP to the IBM i in the first place. He also created XMLSERVICE (toolkit back-end) and is a maintainer of ibm_db2 on the IBM i. One reason Tony comes to ZendCon is to hear from attendees such as yourselves. Normally he stays locked up in his lab. Take advantage of this opportunity to meet him. Watch Tony and me argue and debate in front of the class!

I’m also presenting a session during the regular conference about the PHP Toolkit for IBM i. I’ve updated my presentation with new features of the toolkit and best practices for calling RPG and COBOL.

ZendCon‘s topics are generally advanced ones to enable professional, enterprise-ready development practices. There’s also an IBM i track and plenty of networking time so that IBM i users of PHP can learn from speakers and each other, making the conference appropriate for intermediate users of PHP on IBM i as well.

Hope to see you there, October 27-30, 2014! Remember to register for tutorial day when you register for the conference. Get in touch with questions you’d like answered during my presentations.

ZF2 and DB2 for IBM i

I’d like to address questions about DB2 support in Zend Framework 2.x. Because I helped create the IBM i-friendly DB2 adapter for Zend Framework 1.x, I’ve followed the development of a similar adapter for ZF2.

(updated January 30, 2013, upon the release of ZF 2.1)

Q. Does ZF 2 include an adapter for DB2?
A. Yes! Starting with ZF 2.1, which was released today.

Q. Is Alan’s IBM i-friendly DB2 adapter for Zend Framework 1.x needed in 2.x?
A. No. Because ZF’s Zend_Db equivalent in 2.x works differently than in 1.x, my 1.x component is not needed in 2.x.

Q. Does ZF 2.1’s DB2 adapter work with IBM i?
A. Yes! Please try it and provide feedback to the ZF team.

Which version of Zend Server for IBM i do I have?

Here is the easiest way to learn the version of Zend Server installed on an IBM i system.
[Updated December 20, 2017]

From a 5250 command line, follow these four steps:

1. GO LICPGM
2. Take option 10 (Display installed licensed programs)
3. Scroll down to the licensed program 2ZSVRPI, 6ZSVRPI, or 7PHPZND 
     (on my system, it's the last entry)
4. Read the product description,
     containing version numbers for Zend Server and PHP,
     in the form "Zend Server for IBM i [version] ( PHP [version])"

On my IBM i, I see:
7PHPZND   *INSTALLED   Zend Server for IBM i 9.1.2 ( PHP 7.1 )
so Zend Server is at 9.1.2 and PHP is 7.1.

Thanks to Zend’s Sam Pinkhasov for this tip.

Before you remove Zend Core from your IBM i

If you’ve installed Zend Server for IBM i and are planning to remove the older Zend Core for i5/OS, first check that Zend Core’s version is at least 2.6.1.

Zend Core must be at 2.6.1+ because if you uninstall version 2.6.0 or lower,  portions of Zend Server will be uninstalled as well. Therefore, update your old Zend Core to 2.6.1+ before uninstalling.

IBM i had a solid presence at ZendCon, the Zend/PHP conference. IBM itself was a sponsor and staffed a booth (Tim Rowe and Tony Cairns). Here are a few photos from the conference. I’ll post more when I get time.

NEUGC and COMMON are coming right up

Next week I’ll be in Framingham to present at the Northeast System i Users Groups Conference (NEUGC). In early May,  it’s Minneapolis for the COMMON 2011 annual meeting. Here are the dates and places of these great conferences:

NEUGC: April 11-13, 2011, in Framingham, Mass.
COMMON: May 1-4, 2011, in Minneapolis, Minn.

At each conference I’ll be presenting 6 talks:

  • 4 about PHP on IBM i: web services, batch jobs, Zend Framework, and my research into best practices for db2
  • one about making web development easier with free tools that run in a web browser (a fun one)
  • one non-technical talk about how to stay healthy despite years of professional computer use (fun and interactive)

Both conferences have an exciting lineup of speakers and topics. I plan to learn a lot and meet many great people. If you are there, please say hello.

SSH on IBM i

Secure Shell (SSH), a network protocol used every day by software developers, provides a fast, secure means to transfer files and submit commands to remote servers.

Zend Studio 8.0‘s SSH support allows users to save their PHP scripts onto remote servers such as IBM i.

How to set up SSH on IBM i

SSH runs as a server program, the SSH daemon (sshd). Before sshd can run, it requires a set of public/private key pairs.

Instructions for creating the key pairs and starting the server are given below.  There are two versions of instructions, depending on the version of OS.

IBM i v6.1 and higher: one step creates public/private keys (if needed) and starts server

STRTCPSVR *SSHD

V5R3 and V5R4: two steps are required

1. First, create the public/private key pairs (only needs to be done once):

CALL QP2TERM
ssh-keygen -t rsa1 -f /QOpenSys/QIBM/UserData/SC1/OpenSSH/openssh-3.5p1/etc/ssh_host_key -N ""
ssh-keygen -t dsa -f /QOpenSys/QIBM/UserData/SC1/OpenSSH/openssh-3.5p1/etc/ssh_host_dsa_key -N ""
ssh-keygen -t rsa -f /QOpenSys/QIBM/UserData/SC1/OpenSSH/openssh-3.5p1/etc/ssh_host_rsa_key -N ""

2. Then start sshd (“&” means to run in background):

/usr/sbin/sshd &
Either way, the daemon should now be running. To check, type NETSTAT *CNN on an ordinary 5250 command line. Look for a local port called “ssh” or 22.
For more information about setting up SSH, including prerequisites, see this “Young i Professionals” SSH wiki article and this old but still useful SSH article from Zend’s Knowledge Base.

Zend Framework webinar this Wednesday

On March 9, 2011, I’ll present a free webinar about how to create a Zend Framework project on IBM i. The webinar is at 9am PST, 12pm EST. Sign up here: http://www.zend.com/en/company/news/event/790_webinar-your-first-zend-framework-project-on-ibm-i

Here’s the complete list of my upcoming talks.

Zend Framework community is here to help

A list of Zend Framework user groups is now available online: http://framework.zend.com/community/groups. I’m proud to say the list includes my own New York City area Zend Framework Meetup Group, co-founded by Ed Kietlinski and me in 2009, and affiliated with NY-PHP.

I always learn something from in-person user group meetings, even if I’m the one presenting. I go home with a lot to think about and a good feeling about my profession in technology.
