Have you ever wondered what will happen at your next CICS Cold Start? Perhaps you’ve jiggled your CSD (CICS System Definition) Lists, toyed with CICSPlex SM RASGNDEFs (Resource Assignment Definitions), or maybe it’s the change window for new definitions. How can you predict what will happen at Cold Start?

This article examines the Deployment Analysis feature of IBM CICS Configuration Manger for z/OS. It describes what it does, how it works, and the benefits to you.

Of all the utilities that the mainframe makes available, those used for backup are typically the most useful. To understand why, let's go back briefly to the basics of backup, on the mainframe and in general.

There are two ways to recover from a system crash: rollback/roll-forward (which uses backup) and backup/recovery. In rollback/roll-forward, you keep track of a stream of…

So IBM has reinvented the mainframe, apparently reducing the behemoth to a blade.

Sources say it's ported its precious z/OS to a newfangled 5.2GHz quad-core z processor with two times the cache of the old z10 chip and a hundred new instructions, built a new z196 system round it, stuck it in a chassis, otherwise called a cage, added a BladeCenter Extension - Power7 blades that'll run AIX and x86 blades running Linux - thrown in a Unified Resource Manager and has…

People think they know what business agility is and what it can deliver, but they usually don’t. After reviewing some recent data on users’ attempts to deal with a high rate of change in the business environment (e.g., regulatory changes, dangerous recessions, new issues such as carbon footprint), I’ve come to the conclusion there are three prevalent myths about business agility:

Myth # 1: Attempts to seek agility conflict with cost-cutting and revenue maximization. On the contrary, my studies suggest that in the long run, a pure focus on agility can reduce costs…

On May 17, 2010, IBM celebrated the 10th anniversary of Linux software and services for the IBM mainframe—a cornerstone in the company’s strategy to infuse Linux throughout its portfolio. This article sheds light on the origins of mainframe Linux and its evolution.

How Things Began

Work on the mainframe Linux project started in spring 1998. At that time, the IBM mainframe architecture was ESA/390, defined in 1990; but its successor, z/Architecture, was lurking just over the horizon. Main features of ESA/390 were data space support and serial peripheral attachment via optical fiber (Enterprise Systems…

Business-critical systems must be resilient and scalable to meet the needs of modern organizations. While there’s no better platform than the System z to base such systems on, you must work at it to get the best from it. This article suggests how sites that use CICS Transaction Gateway (CTG) can achieve optimal performance by exploiting z/OS named tokens and the CICSPlex System Manager (SM) Application Program Interface (API).

CTG provides secure, easy access from Java client applications to CICS applications using standard Internet protocols in a range of configurations. You can implement it…

Keeping DB2 objects well-maintained is imperative, but reorganizations can be costly and time-consuming. You can reorganize objects on a schedule or when thresholds are exceeded. For some types of workloads, physically disorganized objects don’t degrade application performance, and reorganizing those objects is a waste of resources.

The main reason to consider reorganizing a DB2 index or table space is increasingly poorly performing SQL. Look at your indexes first. Healthy indexes deliver direct cost savings to an application. But also keep an eye on table spaces. Reorganizing a table space with its associated indexes restores the…

There have been many customers confused about the Integrated Translator since it was introduced, in fact there may still be customers that are not even aware that it exists.  Many times, customers install a new release of CICS and since IBM has always said that applications don’t have to be re-compiled or even re-linked for the new release, they don’t bother to change any of their compile PROCs (procedures).  Of course, if the existing CICS libraries (SDFH**** libraries) contain a version number or reference, those PROCs must be changed to the new library…

Neon Enterprise Software on Thursday said it plans to file a mainframe-related complaint against IBM with the European Commission, compounding the IT giant's mounting regulatory issues in Europe.

Neon, which makes software for mainframe computers, said the complaint is connected with IBM's "on-going anticompetitive and abusive conduct" in the mainframe business. The company did not comment on when it would file the complaint.

IBM has already been slapped with three mainframe antitrust complaints in Europe from…

Today, more than 30 billion transactions and approximately 75 percent of the world’s business data are processed daily on mainframes worldwide. Developers have further strengthened legacy dependence by continuously enhancing these systems with a high level of business customization.

So-called legacy applications on mainframes still deliver significant value. Although business requirements create a need to modernize the application, it isn’t practical to move data and processes to a new platform, especially one that doesn’t ensure the same degree of speed, stability, and reliability as the mainframe.

Developers haven’t been…

When CICSPlex SM was released in the early ’90s, it was widely regarded by the CICS community as a complex beast to install and operate. At its inception, it was released as a chargeable product separate from CICS. To encourage users to try it, IBM (in the U.K., at least) provided a couple of days of free consulting support with the system. This was to assist users in getting it up and running and to provide some guidance on its use! To get the whole system to run well, some significant tuning and configuration were required. That…

A great deal of attention is being focused on the power consumption of IT systems. For example, statistics published by the European Commission Bio Intelligence Service in 2008 found that IT systems accounted for 8 percent of the total electricity usage in the EU in 2005, which is equivalent to 98 megatons of carbon dioxide (CO2). The report went on to predict that this figure would rise to more than 10 percent of total consumption in due course, and put forward some very ambitious targets for reduction. Similar statistics are being gathered and publicized throughout the world.

Admittedly, the definition of IT…

When it comes to mainframe computing, business IT planners and practitioners alike confront a significant challenge that will require an industrywide effort to rectify. These planners have an affirmative view of the mainframe. They agree that it persists as a core platform for corporate computing. Its performance characteristics and cost of ownership advantages over alternative platforms are understood and appreciated. From the standpoint of cost, compliance, continuity and carbon footprint (utility power consumption), the business value case for the mainframe is rock solid and is even underscored by both current economic realities and the prevailing regulatory climate.

I’m just back from WAVV, and a grand time was had by all. More than 150 customers, vendors, and IBMers spent four days in Covington, KY (just outside Cincinnati), talking about z/VM, z/VSE, and Linux on System z. Although WAVV may not hold its conventions in the hot spots of the convention universe, it’s an all-volunteer organization that delivers a great bargain for System z education. You can also use it as a vehicle to tell IBM—and other vendors—what features and functions you’d like to see in upgrades…
