Hot Topics 2019
Cryptographic Support for z/OS V2R2 - z/OS V2R3, also known as ICSF FMID HCR77D0 or web deliverable number 18, was released in December of 2018. The updates contained in this release vary from support for new algorithms and new security features to availability enhancements for the ICSF started task.
Pervasive encryption is a consumable approach to enable extensive encryption associated with protecting data and achieving compliance mandates. With the z14, you can encrypt all data—in flight and at rest—faster, and less expensively. Pervasive encryption capabilities on the z14 enable you to protect data efficiently, allowing you to encrypt data at the database, data set and disk level, with no changes to applications.
To give developers a friendly user experience when developing for IBM Z*, we need to shift away from traditional models of resource consumption and understand how resources are readily consumed in the rest of the development world. With the click of a button, developers can now receive databases, application servers, message queues and seemingly endless other resources. Developers’ ability to manage their own environments is now a staple. Without it, agility and efficiency is lost. This is precisely where IBM z/OS Cloud Broker helps bridge the gap for workloads on z/OS.
IBM z/OS Container Extensions (zCX) is a new z/OS 2.4 feature that enables clients to deploy Linux on Z applications as Docker containers in a z/OS system to directly support z/OS workloads. This is done without provisioning a separate Linux server, maintains operational control within z/OS and is supported by z/OS Qualities of Service (QoS). This article provides answers to the most commonly asked questions about zCX
Do you have IBM Z host crypto modules and want to manage them using the most secure tool and processes available? Do you find the thought of using Trusted Key Entry (TKE) overwhelming? Well, don’t worry. TKE has a set of wizards for you to use to help uncomplicate things.
I work on the IBM Z Academic Initiative team and each day I hear similar questions. Are young folks interested in this technology? Are schools teaching the mainframe? How have other companies addressed their retiring workforce? A large percentage of my team is retirement-eligible, can you help? Do these questions sound familiar? If so, you’re in the right place! We helped some amazing clients and students to share their stories with you.
Hot Topics 2018
IBM Z Hardware Management Console (HMC) customers wanted a quick way to learn about some of the latest HMC features. In response, we created some YouTube videos, which provide task-centered visual instructions to complement the documentation we already provide.
The IBM Signed Secure PDF Transform feature enables users to sign PDF documents produced by IBM Print Transform from AFP to PDF for Infoprint Server for z/OS. It builds on the base of the AFP to PDF product to produce a digitally signed PDF by applying a digital certificate to the PDF content. It also provides additional security to prevent changes to sensitive transactional documents and to enable tamper detection.
With hundreds of z/OS and related books in the IBM Knowledge Center along with countless other resources scattered throughout the web, finding information about z/OS offerings can be overwhelming. When you do find information, it can be difficult to know where to start, and what steps to take. The resolution to these challenges? IBM Z content solutions.
Container Pricing for IBM Z* allows IBM to deliver a revolution in the pricing of qualified solutions on z/OS*: pricing that’s not affected by the cost of unrelated software or whether the solution runs during a peak time. IBM has designed a set of solutions around the framework, each of which targets a key requirement of z/OS clients.
In the present cognitive computing world, data is everything. By the year 2020, enterprises will have accumulated 44 ZB (zettabytes) of data. Much of that data includes highly valuable information about an enterprise itself or the individuals associated with the enterprise—for example, the Personally Identifiable Information (PII) of employees or customers. To protect such data, an enterprise must have a secured infrastructure and databases.
Cryptographic Support for z/OS V2R1 - z/OS V2R3, also known as ICSF FMID HCR77C1 or web deliverable number 17, was released in September of 2017 and has many things to brag about. The updates contained in this release vary from usability improvements, such as an ISPF-based browser for CKDS key material, to integrated support for a PCI HSM configured CCA coprocessor.
As stated in the IBM Software Announcement 218-118, dated March 6, 2018, you soon will no longer have the delivery on tape media option for your z/OS product or service orders. As of July 1, 2018, the only supported delivery methods will be Internet and DVD with an effective date of July 16, 2018. Now would be a good time to begin using an alternate delivery method. Internet delivery is the recommended method and is used for nearly 90 percent of z/OS software orders. If you require a physical delivery method, choose DVD.
Looking for the “z/OS* V2.3 Migration” book? Don’t look now, but it’s been transformed into an IBM z/OS Management Facility (z/OSMF) workflow. For the past decade, whenever you upgraded to a new release of z/OS, you turned to the venerable migration book. You’ve come to rely on this critical asset for all the important details.
Think back to your first day working on the mainframe. You were probably completely overwhelmed and wondering why everything had to be so complicated. To make matters worse, the mainframe has developed its own culture, terminology and library of acronyms that seem like they were inherited from a sci-fi novel. It’s confusing and there’s so much to learn. How can someone new to the mainframe platform ever expect to catch up, much less have fun with it? This is where the “Terminal Talk” podcast can help.
Learn how to augment information from AFP input and produce accessible PDF output that’s compliant with the ISO 14289-1 PDF/UA standard or WCAG 2.0 AA.
z/OS V2.3 delivers enhancements to the z/OS platform’s cloud capabilities that you can use to begin your transformation from an IT cost center to a value-generating service provider, delivering world-class services internally over the intranet or externally over the internet. These enhancements, referred as IBM Cloud Provisioning and Management for z/OS, were also rolled back to z/OS V2.2 (with PTFs UI42847 and UI46543) and z/OS V2.1 (with PTF UI43814).
