By Denny Yost, ETJ Magazine (5-minute read)






If you have ever been responsible for maintaining ICF catalogs and VSAM clusters, it probably reminds you of playing the arcade game Whac-A-Mole. Just when you think everything is under control, a broken index is detected for a VSAM object. Or, the CA/CI splits you fixed the other day, really didn’t get fixed. Or, the myriad of other fun things that can go wrong decide to do so on a Friday afternoon at a busy time for your company or organization. Can you still remember the feeling you experienced the last time it happened?

Dino-Software continues to excel at taking on and easing the challenge of working with VSAM files and catalogs through its T-REX product solution. T-REX is a proven mainframe utility that analyzes, diagnoses, reorganizes, reports, backs-up and repairs clusters and assists with the overall maintenance to ensure continuous operational capabilities of the ICF catalog components in a z/OS environment.

For many years, T-REX has aided in the monitoring and maintenance of catalog and cluster health to minimize this tedious and time-consuming task. T-REX provides invaluable assistance to those professionals tasked with ensuring the ICF environment and VSAM clusters perform with consistency, accuracy and reliability by delivering:

T-REX provides standard reports emulating IDCAMS LISTCAT output, but provides a much higher degree of selectivity coupled with high-speed performance. In fact, almost every attribute and characteristic of a cataloged data set entry can be used as selection criteria, including “Boolean” operator support for variable values. With a proper plan for implementing proactive diagnostics, T-REX provides a viable mechanism for detecting and reporting errors before there is a negative impact to production operations.

Introducing T-REX V7.3

The newest version of T-REX introduces numerous enhancements further easing the management of ICF catalog environments. The enhancements are split between z/OS 2.3 support and batch.

z/OS 2.3 Enhancements

T-REX V7.3 provides the following z/OS 2.3 enhancements:

T-REX Batch Enhancements

The T-REX V7.3 batch enhancements greatly extend the product’s capabilities. These batch enhancements include:

T-REX was developed by the original Softworks developers who devised the Mechanic and later Catalog Solution over 20 years ago. The developers applied their collective experience to incorporate modern design methodologies and technology to produce the latest, state-of-the-art catalog management product available. Additionally, the technical support staff is comprised of seasoned veterans of z/OS and the ICF catalog environment. T-REX can repair any VSAM object (BCS, KSDS and Variable RRDS) with a broken index within minutes.
