Rational Developer for System z (RDz), IBM’s z/OS Eclipse-based Integrated Development Environment (IDE), has been in widespread use for seven years. In that time, it’s simplified and improved the professional lives of z/OS programmers doing traditional application maintenance and enterprise modernization. It has made developers more productive and saved their companies a lot of money.

It did all that by streamlining and refactoring arcane z/OS development processes into structured, efficient analysis, editing and testing operations, sustained by modern Graphical User Interface (GUI) tools (Eclipse), wizards, and menus—perfect for…

Before deciding whether or not to use a DB2 partitioned table space, it’s wise to weigh the pros and cons. The following applies to partitioning in general and all types of partitioning, including index-controlled, table-controlled, and universal partition-by-range.

Advantages of a Partitioned Table Space

Each partition can be placed on a different disk volume to increase access efficiency. Of course, this is more difficult, if not impossible, to accomplish with RAID storage devices, so this doesn’t generally apply to shops using modern disk storage arrays.

Partitioned table spaces can…

Most application performance problems involve searching and scrolling. Once you find what you’re looking for, you generally can process it quickly. However, with increased use of automated interfaces, frameworks, and generic coding techniques and tools, this problem seems magnified. While changing programming techniques and customizing code is time-consuming, it’s necessary if you want to save processing time and costs over the life of an application. Besides, you typically apply custom solutions as the exception, not the rule, when building an application.

The techniques presented here can help you solve performance issues when using…

 The English village of Bucklebury, which lies about two miles from my home, has achieved instant fame as the family home of Kate Middleton, Prince William’s new wife and the U.K.’s future queen. In the weeks leading up to the royal wedding, the village was besieged by journalists and paparazzi of every nationality, as well as curious sightseers and coach trippers, all anxious to catch a glimpse of the duck ponds, quaint shops, and thatched roofs that reportedly characterized the princess’s idyllic existence. Bucklebury provided all the ingredients for a Disney-esque,…

Here we consider TCP/IP under z/OS, a path into the system we need to control for effective security. Using tools provided with z/OS, this can be the most secure TCP/IP you’ll find anywhere. We’ll summarize how TCP/IP works under z/OS, discuss its security risks, and examine how you can manage those risks. References to security software here mean RACF, ACF2, or TopSecret.

Each TCP/IP message contains an IP address used for routing. The IP address is like a phone number and often corresponds to one computer…

Callout: Over half of the 376 companies surveyed indicated they’re planning to hire new mainframers straight out of college or university, but they have concerns that these employees won’t be fully prepared to take on mainframe responsibilities.

The journey to a bright future for the mainframe and large enterprise computing community is clearly under way! This realization hit me during SHARE in Anaheim this past February in the middle of a meeting with Dayton Semerjian, head of CA Technologies Mainframe business, and members of the SHARE board of directors, including SHARE president Janet Sun.…

Software enables us to implement automation, which makes it possible to quickly respond to alerts and problems, freeing up technical staff to do more complex, strategic tasks. Automation helps IT move from firefighting mode to proactive management. With the adoption of automated alert processing and REXX programming standards, the problem resolution forecast in your z/OS data center is for clear skies. This article demonstrates how to define standards and then use the REXX programming language to set up the automation.

Automation Alert Processing Standards

Creating automation alerts is a basic, primary goal of…

The mainframe has most certainly defied the predictions of industry pundits; in fact, in the past 10 years, most mainframe shops have grown their MIPS capacity by 15 to 25 percent per year. This  increase reflects both more work and new kinds of work. The “new workloads” may be z/OS transactions arriving from outboard distributed servers or UNIX applications now running under Linux on System z on Integrated Facility for Linux (IFL) processors. The result is a significantly larger mainframe presence than the pundits anticipated.  

Systems management strengths, disciplines and tooling that have grown up…

On April 12, 2011, IBM provided a preview announcement of z/VSE Version 5.1. This announcement, which is available at http://www-03.ibm.com/systems/z/os/zvse/, outlines the major items that will be available in the next version.

It was interesting this announcement came just four and a half months after delivery of z/VSE 4.3, which also contained significant functionality. The announced delivery date for z/VSE 5.1 is fall 2011—just one year after z/VSE 4.3 became available.

A business provides value by meeting the needs of its customers. To deliver better service to customers, both the business and the IT department must understand the impact of any problems that occur with technology components or applications. When an application or technology component experiences a performance issue or a failure, how does the business or the IT department know exactly what business process or business transaction was affected and what impact it had on the business?

When your business and IT department are truly integrated, you can maximize the value of the information technology, which, in…

Just like Dr. McCoy and Captain Kirk in the “Star Trek” episodes where all hope seemed lost, from the doom and gloom of my last commentary, we move on to discuss the final acquisition of Novell by Attachmate. Yes, the heavy door of final approval has slammed shut on the formal approval of the deal by both companies, and the merger is complete. In a mass email to customers, the new management promised to continue to provide support for the SLES operating system and tools, and to maintain the support services familiar to Novell customers. So far,…

Mainframes need to get their sex appeal back, as they were back in the day; in their geek-chic way.

I work at an outsourcing company and we have front row seats to multiple computer environments. We have seen numerous mainframe-centric companies try to distribute their workload across their server farm. And when someone there has the fortitude to sit down and crunch the real numbers of what they really have to do to run the new behemoth (versus what the vendor White Papers claim), they typically find overall increases in equipment…
