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.
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.
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.
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).

RACF Ghost Busted: Easily Finding and Fixing Ghost Profiles
December 2017 | by Jun Ogata, Scott Woolley
Is your RACF database still haunted by ghost profiles? Do you enter the SEARCH command and still find (apparently) generic profiles that you are unable to change? Well the folks that brought you the “RACF Ghost Hunters” Hot Topics article have some great news for you. Your RACF ghosts are now busted!
Security is a principle concern in today’s world, and the secure handling of data is an essential component of security. Cryptographic Support for z/OS V2.1 to z/OS V2.3, provides a means for the secure and reliable handling of data with Crypto Statistics Monitor. It helps security administrators and capacity planners monitor the use of cryptographic resources and shows which resources are being used, how much these resources are being used, and who is using these resources.
With the increasing number corporate, industry, and government regulations regarding cryptographic protection of data in flight, as well as discoveries of weaknesses in existing cryptographic protocols and algorithms, it has become very important that z/OS administrators and auditors have a way to assess the quality of the cryptographic network protection being applied to their key z/OS workloads.
Aggregate Content for IBM Z Products With IBM Doc Buddy V2
October 2017 | by Alicia Mao, Emily Siu, Yvonne Ma
With the IBM Doc Buddy mobile app, you can search messages and codes issued from IBM Z products online and offline. You can also locate helpful Mainframe information (including blogs, videos, and IBM Knowledge Center topics) on the Doc Buddy App.
The new Metering and Capping support allows the system capacity planner more granular control over CPU and memory consumption for various workloads and enables the system to host new workloads more easily. You can use this new support to ensure resource-hungry workloads, such as z/OS Platform for Apache Spark (z/OS Spark), coexist nicely alongside other production workloads.
The end of Moore's Law has meant that hardware no longer gets free performance boosts every generation; instead, IBM provides capacity by increasing the number of engines, and by making architectural changes to both the hardware and software to make sure they work well together. Be sure to check out these configuration best practices.
Businesses must constantly adapt to changing conditions: competitors introduce new offerings, consumer habits evolve, the economic and political environment change, etc. While this isn’t new, the velocity at which business conditions change is accelerating. This pace of change places a new burden on technology solutions developed for a business, creating a unique opportunity for machine learning, which is designed to address the fluid nature of these problems.
We're excited to announce that Hot Topics articles (content formerly contained in the z/OS Hot Topics Newsletter) will now be hosted on the IBM Systems Magazine, Mainframe edition, website from the Hot Topics landing page and shared across multiple distribution channels. Going digital allows us to connect with more of you and allows us to get information to you quickly.
