  • The Right Time for End-to-End Management

    This is the first of a series of posts on end-to-end monitoring and management. End-to-end management is about visibility to all aspects of an application including OS, network, middleware, database and the application itself. This visibility makes management effective, otherwise you are constrained when problems occur. History has shown this quest to be a tough challenge.

    COBOL Has What Is Needed to Solve Challenges

    In my previous post, I wrote that COBOL is a language that was designed to meet business needs by making use of the automation supplied through computer programs and systems. It is so useful that you can take motivated people with no computer training and turn them into COBOL programmers. This is true today as it was 30 years ago. What is it about COBOL that gives it this timeless characteristic?

    Programming Languages: COBOL Means Business

    In my previous post, I wrote that COBOL has grown and thrived for 50 years. I also wrote that in the past, COBOL did not get significant attention in universities because the business nature of COBOL did not match the math and science focus of computer science departments. Nevertheless, COBOL is a programming language with powerful capabilities and straightforward effectiveness.

    Programming Languages: What About COBOL?

    In my previous post, I continued a discussion about Basic Assembler Language (BAL) that I had begun the week before. BAL is still useful is a funny way of putting it, because in certain contexts BAL is indispensible. Consider this: Everyone who makes a living as a programmer should write in the BAL of their favorite machine so they can grow from the lessons that this experience teaches them. So what about COBOL, how is it doing?

    The Dance Between Machine and Its Language

    In my previous series of posts, I went on an excursion into z/OS automation starting with Focusing on Usability and Automation: Message Processing Facility and continuing with z/OS Jewel Keeper: SYS1.PARMLIB, Automating From Start Up to Shut Down: NetView and finished with Building on NetView: Tivoli System Automation for z/OS. I hope that series was useful and interesting.

    Building on NetView: Tivoli System Automation for z/OS

    In my previous post, I wrote that NetView can be used by itself to automate systems and networks or it can be used as a base upon which can be added other automation products to speed up the process of automating a system. The other automation product I was writing about is Tivoli System Automation for z/OS.

    Automating From Start Up to Shut Down: NetView

    In my previous post I wrote about SYS1.PARMLIB and made a specific focus on members that pertained to automation including COMMNDxx, IEFSSNxx and MPFLSTxx.  In this post I want to explain the role of NetView in system automation.

    z/OS Jewel Keeper: SYS1.PARMLIB

    In my previous post, I wrote that the Message Processing Facility (MPF) of z/OS is at the intersection of usability and automation.

    Focusing on Usability and Automation: Message Processing Facility

    In my previous post I wrote that Job Control Language (JCL) is very straightforward. If it is complex at all it is because it is used with programs whose conventions are not always understood. In this post, I want to explain a component of z/OS that you might not know about.

    Essential and Under-Appreciated: Job Control Language

    In my previous post, I wrote about the VSAM and how many application programmers and support personnel use it here. Everyone who works with z/OS has probably had some contact with the VSAM access method and its utility named IDCAMS. This is true to an even greater level for Job Control Language (JCL).
