T-REX V7.2 From Dino-Software Further Aids Catalog Management
By Denny Yost, ETJ Magazine (5-minute read)
Chances are good that when it comes to working with VSAM files or catalogs you have been there, done that and don't have find memories of the experience. For example, do you cringe anytime someone mentions the need to mend a VSAM broken index that occurred in the middle of the night or having to use IBM's Access Method Services (IDCAMS) utility for just about anything? Or what about untimely processing failures because you weren't aware that a BCS had reached the maximum number of allowable extents? It would be easy to mention many other VSAM and catalog management... Read More

Catalog Basics - Part 1 – Catalog Components

By Blair Svihra, Dino-Software (Restricted Member Content)
It could be argued that the catalog environment could be expanded to include a discussion including any one of the five major Tape Management Catalogs (TMCs) and/or IBM’s Hierarchical Storage Manager (HSM) offering, but these topics can be discussed in detail in a later white-paper. A catalog allows access to a data set without having to know its physical location. Let’s look at all three components and how they are related.

VELOCI-Raptor Release 5.1 – Enabling Applications to Perform at Their Peak
By Denny Yost, ETJ Magazine (5-minute read)
With a significant percent of Fortune 500 size organization’s running on mainframe systems, their value and importance are critical to the continued success of the enterprise. Yet, running these applications in the most efficient manner possible to speed execution time and minimize resource usage continues to be challenging if the proper steps are not taken.  A key area of focus is always determining and setting the best buffering environment for an application when accessing VSAM and non-VSAM data.  Read More

Proactively Controlling the Swarm
By Jeremy Schilke, Dino-Software (4-minute read)
Perhaps the “per byte” price of storage has dropped, but due to the sheer rate and volume by which data is produced and retained, the reality is that the overall effort and cost has not lessened. Furthermore, collecting, organizing, protecting and then ensuring accessibility...

Reduces Costs, Eases Storage Management Through a Single Pane of Glass
By Denny Yost, ETJ Magazine (5-minute read)
The Challenges – Today, most Fortune 500 size companies have an abundance of mission-critical data to manage that continues to grow at a seemingly never-ending pace. At the same time, z/OS storage management personnel with decades of experience are retiring and less experienced personnel are agonizing under the load of trying to manage this data while attempting to quickly gain the vast experience needed to manage these environments.

Mysteries of Buffer Optimization Solved!

A Good Buffering Product Does It Automatically – and Does It All the Time
By Bill Hitefield, Dino-Software (12-minute read)
In some respects, IBM’s access methods (especially VSAM) are like software black boxes – you pass a request to them, they go off into the Enchanted Forest, and sometime later, data is either retrieved or written by your application. As application developers, we have some modicum of control over when, why, and how often we make requests to the access method. It is that second part of the process, the “sometime later,” that we view as a part of application performance that we seemingly have no means of influencing. Read More . . .
