Counting on her 20+ years’ experience on the mainframe, Karine Le Boulanger – z/OS System Expert at Orange France – is definitely an expert of the product, and that’s why we thought that no one better than her could have said why Mainframe matters.
I had the chance to meet her at the latest User Group France, and asked her views on Workload Automation for Z.
1. We believe that #MainframeMatters and at Orange you do too, since you invested in it since years. So, what do you think that are the advantages of mainframe in today’s IT world?
The mainframe brings reliability, security, it remains one of the safest environments on the market, and more is always competitive: with new developments and regular changes. The mainframe remains an extremely powerful machine and I am proud to work on this environment.
2. Could you tell us more about your experience with the WSz, how do you use it? WSz 9.3 is installed on our LPAR, I am the person who installed the latest version of WSz. I have been working on OPC now for 20 years, I work in the system team, so we are in charge of the upgrade of software systems, network, security, storage. WSz is part of the software that we maintain, so we intervene on the upgrade of WSz and in case of an incident, and we must admit that the problems with WSz are very few.
3. Are there some recent features that have helped you improve the way you work? Today we are strongly interested in Zowe and especially the connection between Zowe and WSz.
4. What do you like most from our product? I like the reliability and the solidity of this product, and I wish I had more time to discover and test more new features. Also, I would be happy to use a friendly WSz interface, such as the Dynamic Workload Console.
Mainframe is definitely more alive than ever. As recently stated by an IBM executive, it “essentially keeps the world running”. No wonder then that we keep talking about mainframe modernization, while adding new features and releasing new major versions of WSz, such as the 9.5.
While the latest version confirms the characteristics which made WSz so great - reliability, stability and high performances – it moves one step further by enhancing capabilities such as predictive analysis, what-if, auditability and security.
Plus, making the most out of a single point of access and monitoring, WSz allows hybrid workload automation and bring the mainframe in everybody’s hands, thanks to graphical interfaces, which significantly reduce the adoption curve for new users.
So, what about you? Why do you think that #MainframeMatters?
Tell us your experience with the workload scheduler on mainframe and share it with our community.
Just drop me a line at email@example.com: can’t wait to hear about it!
You can use the agent for z/OS - aka D-Driven - to schedule work using IBM Workload Scheduler. You install and configure the agent for z/OS in the z/OS system and this work as any other dynamic agent. As soon as it is configured, the agent automatically links with the dynamic domain manager component of IBM Workload Scheduler through the HTTP or HTTPS protocols. With the agent for z/OS you can define jobs and schedules on IBM Workload Scheduler and submit a subset of the jobs to a z/OS system and you run the planning tasks on IBM Workload Scheduler while the execution is demanded to the z/OS system.
Securing communications in the Workload Automation environment is an essential step to meet your company’s security requirements. Does Workload Automation use a secure communication mechanism? The answer is yes! All communication is implemented over SSL protocol TLSv1.2. Read this blog to find out how to implement security correctly in a v9.5 environment by customizing default certificates.
“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:
Nowadays, industries move towards microservice and cloud native architectures that makes use of containers to scale and deploy applications. But containers have its own challenges and adds complexity to the infrastructure to maintain especially in large dynamic environments (if you are not familiar with containers and Kubernetes don’t worry: catch up with our latest post, Containers and Workload Automation 101).
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.
All the questions you never dared ask about containers, Docker and Kubernetes
You have heard a lot about containers in the last years, but you still do not know how you can leverage them with Workload Automation? This is the right place to start then.
We collected the most frequent questions our users do when we talk about containers.
