Want to learn how to automate and optimize Db2 utility processing without changing existing application jobs?
Webinar: June 4, 2026 - Click to see webinar times

In this Enterprise Tech Journal and Log-On Software webinar, we will show how Total Utility Control (TUC) from Log-On Software allows Db2 administrators to introduce intelligent automation into existing utility environments while preserving application logic, scheduling integrity, and operational consistency.

Topics covered will include:

• Taking control of online utility ex*****on
• Managing utility dependencies automatically
• Converging utility processing for improved efficiency
• Policy-driven conditional processing
• Runtime extraction of REORG DISCARD and UNLOAD conditions
• Auditability and reporting using SNAP capabilities

You will learn how TUC helps organizations simplify administration, reduce operational overhead, and improve utility processing efficiency - all while allowing legacy application utility jobs to remain intact (i.e. no application changes).
If your Db2 environment depends on large numbers of difficult to maintain legacy utility jobs, this webinar will provide practical strategies for introducing modern automation safely and incrementally.

MAINFRAME HISTORY
One of the greatest achievements in computing history was not speed. It was RELIABILITY.

From the earliest days of the IBM System/360 in 1964, IBM engineers understood something critical: Businesses could tolerate slow computers far more easily than unavailable computers.

Banks, airlines, insurance companies, governments, retailers, and stock exchanges all needed systems that simply could not fail.

Mainframes became famous for:
• Years of continuous uptime
• Massive redundancy
• Error-correcting memory
• Hot-swappable components
• Automatic recovery systems
• Transaction integrity
• Near-zero unplanned downtime.

Many mainframe installations have operated for years without an unscheduled outage.

MAINFRAME HISTORY
In 1955, a group of IBM 704 users made a decision that would quietly change the trajectory of enterprise computing. They formed SHARE.

SHARE was not a vendor initiative and not an IBM program — it was a user-driven collaboration.

In the 1950s, IBM delivered powerful hardware — but very little system software. Every customer was forced to:

* Build their own utilities
* Modify compilers
* Create operating environments from scratch.

The result — massive duplication of effort across the industry.

SHARE’s founding principle was simple — and radical: “Let’s share what we build.”

Members began:

* Exchanging source code
* Building a common software library
* Collaborating across companies — even competitors.

SHARE quickly became the center of gravity for mainframe software innovation:

* The SHARE Library — one of the first large-scale code repositories
* SOS (SHARE Operating System) — developed collectively in 1959
* Direct influence on IBM’s own OS strategy, including OS/360.

In effect, SHARE became the first true software ecosystem in enterprise computing.

MAINFRAME HISTORY
The first z mainframe, the IBM z900, was introduced on October 3, 2000. It was the system that launched the modern z/Architecture era.

It delivered 64-bit computing (while still supporting 24 and 31-bit apps). It had “zero downtime” design with built-in redundancy, and powerful virtualization via PR/SM and LPARs

The result? One machine acting as many— running z/OS, z/VM, z/VSE, z/TPF, and eventually Linux. The z900 didn’t replace the past— it protected it while moving forward.

From the z900 to today’s z17, that foundation still defines the platform.

MAINFRAME HISTORY
When you think of IBM, you probably picture the iconic blue logo with horizontal stripes. But that logo didn’t start that way—and its evolution mirrors the rise of the modern mainframe era.

1889–1924
Before IBM existed, its predecessor (CTR) used a traditional industrial-style emblem— nothing like today’s clean corporate identity.

1924 — The Birth of “IBM”
When the company became IBM, the first official logo featured a globe — signaling global ambition even then.

1947 — The Bold Shift
IBM adopted a simple, solid “IBM” wordmark. Clean. Strong. Corporate.
This was the beginning of the identity we recognize today.

1956 — Enter Paul Rand
Legendary designer Paul Rand refined the logo into the modern, geometric style —introducing balance, proportion, and timeless simplicity.

1967–1972 — The Stripes Appear
Paul Rand added the horizontal stripes —first 13, then 8.

The striped IBM logo rose to prominence during the System/360 mainframe era, one of the most important milestones in computing history.

While hardware, software, and architectures evolved dramatically over the decades — the IBM logo remained remarkably consistent.
