IBM Ready to Announce Power6-Based System i Box

July 26, 2007 Timothy Prickett Morgan

During IBM‘s conference call with Wall Street analysts last week, the company’s chief financial officer, Mark Loughridge, confirmed the rumors that have been going around that IBM would be soon announcing a Power6-based server with the System i moniker on it.

Specifically, Loughridge said it would be announced later in the third quarter, but he might just as well have said sooner in the third quarter because the announcement is, in fact, tomorrow.

IBM has only announced one Power6-based server so far, a System p 570 server that has been tweaked to support the Power6 chip instead of the

Avoid Large Local Variables in Modules

July 25, 2007 Ted Holt

In two previous articles, I dealt with some program design practices that can cause performance problems. Today, I deal with another area where large variables can have a derogatory impact on performance, and I show you a couple of ways to get around the problem. I use RPG for my examples, but the principle applies to any language.

Let’s say we need three string-handling subprocedures–I’ll call them DoThis, DoThat, and DoTheOther–that will be used in many programs. Since they’re used so widely, let’s put them into a service program. Let’s say further that each of these subprocedures accepts two 64K

Memory Management: It’s Your Fault, Now Fix It

July 25, 2007 Doug Mewmaw

This year, I will be on the AS/400 platform for 19 years. Wow–where did that time go? All those years working with peers, customers and the like, I’m convinced that the performance component that is the most misunderstood, is memory. In a previous article, I explained about the importance of the machine pool and we looked at the Performance Adjuster feature of i5/OS as well. The feedback I received from that article proved to me that we need more articles on managing memory.

I would like to share some neat tricks of the trade and best practice techniques that

Admin Alert: Getting Around System i Default Passwords, Part 1

July 25, 2007 Joe Hertvik

Since processing time immemorial, i5/OS and OS/400 computers have had problems with default passwords. Default passwords occur when a user password is equal to its corresponding user profile name. They are mostly created by the system’s user creation commands, and i5/OS administrators can spend a lot of time finding and changing these hacker magnets. This week, I’ll examine the dynamics of System i default passwords and how they are created.

Today’s article is part one of a two-part series exploring default passwords and their creation, detection, and prevention. This week, I’ll explore the mechanics of how default passwords are created

IBM Upgrades High-End System i Server with Power6

July 24, 2007 Timothy Prickett Morgan

Mirroring what IBM‘s formerly independent System p division did back in May, the Power Systems division–the amalgam of the System p division and the high-end of the now broken up System i division, which was created last week–has announced its first product. It is the first server with the System i brand that makes use of the dual-core Power6 processor. The machine bears a strong resemblance to the rejiggered System p 570 that Big Blue announced back in May.

While IBM may have split the System i division into two pieces, one that merged with its AIX and Linux

IBM Previews i5/OS V6R1, Due in 2008

July 24, 2007 Timothy Prickett Morgan

Well, the mystery about the naming and timing of the next release of the i5/OS operating system is over as of today. Last year, IBM hinted that it might come out some time this year, and there were even rumors in late 2006 that indicated IBM might ship what was tentatively called V5R5 in March 2007–perhaps on existing Power5+ machines, perhaps on a new line of Power6 servers.

As it turns out, the forthcoming System i operating system will be called i5/OS V6R1, in keeping with the naming convention used for IBM’s AIX Unix variant and the Power6 platform. And

EMC Offers Hardware-Based HA Alternative

July 24, 2007 Alex Woodie

While EMC is best known in the System i world as the platform’s only other provider of external disk besides IBM, a surprising number of EMC’s System i customers also utilize the company’s high availability offerings. What’s more, customers can use EMC’s HA and DR offerings, called TimeFinder and SRDF, not only to augment their System i servers, but to protect their Unix, Linux, NetWare, and Windows servers, thereby reducing complexity while boosting resiliency.

There was a time when only the biggest shops in the land could afford to even think about investing in a storage area network (SAN),

SugarCRM Now Available for i5/OS

July 24, 2007 Alex Woodie

The transformation of System i into a platform for running cutting-edge, open source applications continued today when SugarCRM announced the availability of its customer relationship management (CRM) application for i5/OS. Sugar Enterprise, as the software is called, was written in PHP and uses Zend‘s PHP runtime environment and MySQL‘s open source database.

SugarCRM is a SourceForge success story. The story starts in April 2004, when John Roberts, Clint Oram, and Jacob Taylor began an open source application development project on the Sourceforge Web site, which was set up to foster communication among programmers and other advocates of the
