“Mainframe essentially keeps the world running."
It may sound bold but it’s true. The quote above, which is from an IBM executive , Philip MacLochlainn, is indeed supported by stunning figures: “85% of all credit cards, 29 billion ATM transactions per year, 92 of the top 100 banks ... 12 billion passenger flights are booked” thanks to mainframe. And it makes no wonder to whom is familiar with mainframe’s history and the story of workload scheduling and management, which we contributed to write.
In the last few years there is a lot of focus around “Mainframe Modernization” … and there are multiple reasons for this focus and great benefit for the enterprises that will embrace this journey. In the journey to Cloud, the market is entering in a new chapter, while in the initial phase, that we call chapter 1, the focus and the plan was to migrate existing workload and application to Cloud, with a modernization of the IT and build new application as Cloud-ready, in the new chapter (Chapter 2) the focus on “migration “ was strongly reduced for multiple reasons.
Workload Automation and SAP: all you need to know about Dynamic SAP R/3 Jobs and Associated Return Codes
There are fundamentally 3 ways to define Standard SAP Batch Jobs in IWS :
Delegate administrative tasks to other users in your Workload Automation on Cloud subscription folder
LET’S INTRODUCE what’s new
Get familiar with the new concepts introduced by Workload Automation on Cloud that leverage the 9.5 Fix Pack 1 on-premise version, released in July:
IBM Z Workload Scheduler collects many information about its workload execution and data base definitions in different formats. You can obtain info from messages issued on SYSTEM and/or on IzWS product LOG, or you can obtain it from AUDIT function reports.
Starting from this info, an analysis can be done to better tuning workload, prevent problems and so on.
A new easy way to Create, Modify, Replace and Backup Variable Tables
The Workload Automation Programming Language (WAPL) interface allows to easily manage Variable Tables through batch jobs. In fact, it supplies a Batch Loader-like processor through which it is possible to CREATE and MANIPULATE variable tables inside IBM Workload Scheduler Database.
Currently Workload Automation customers are moving increasingly to dynamic agent scheduling managed by Dynamic Broker component (ITDWB enterprise application). Dynamic agent scheduling introduces additional processing to the traditional one.
There are multiple processing steps between job execute notification, via mailman server, to Broker component and the final job dispatch to the remote JobManager. All these steps correspond to an internal job status in the JOB_BROKER_JOBS table in the DWB schema that map to WAIT status in the plan (which could be check using conman or the Dynamic Console). The WAIT status means, as documented, that the job is waiting to fulfill its dependencies. In this blog, it is explained how to retrieve a meaningful detailed status of Jobs.
Workload Scheduler 9.4 Fix Pack 1 was recently released, and among the numerous enhancements for the Dynamic Workload Console (DWC) - a web interface of the product and the main access point for the cloud solution to automate and orchestrate workloads through the cloud – the new Graphical Views are the most compelling with a new modern look!
Read more about the 9.4 Fix Pack 1 release!
IBM and HCL just released new enhancements with Workload Scheduler (TWS) version 9.4 Fix Pack 1, that from one side push the product on the road of a transformation strategy for Cloud, Docker and DevOps, and on the other side address many “Requests for Enhancements” from existing customers.
These new features make TWS a complete product for both enterprise and business digital automation that is required from modern application development and deployment methodologies.
One of the top features of the IBM Workload Scheduler (aka TWS) is the What-If Analysis capability: an advanced simulation tool built to help IBM Workload Automation customers understand the possible impact of changes on their workload.
What-if Analysis is a predictive tool able to represent your workload using a Gantt View, to display scheduled activities faster and give you a visual representation of your workload that at a glance gives feedback about workload health.
