Overview

Top rule

IBM® z/OS® is designed to keep applications and data available, systems highly secure, server utilization high, and to enable agile development. z/OS continuous delivery (CD) offers clients the opportunity to use new z/OS functions, capabilities, and technologies by applying service rather than upgrading to a new z/OS release.

This quarter’s CD update further extends the capabilities of z/OS V2.4 with enhancements and functions that can benefit clients across areas of systems operations, automation, management, and security. Key features delivered in this second-quarter CD release in support of z/OS V2.4 include the following:

  • Enhanced Base Control Program internal interface (BCPii ). Enhancements include a new z/OS API named HWIREST that enables applications to access many previously unavailable attributes of the IBM z15.™
  • Improved Tailored Fit Pricing (TFP) for IBM Z®. A new system parameter that automatically reports and applies the TFP solution to the system. This improvement is designed to be an easier and less error-prone alternative to defining TFP solutions with the Sub-capacity Reporting Tool (SCRT) control statements.
  • Enhanced IBM z/OS Management Facility (z/OSMF). Improvements include a global configuration to the Interactive System Productivity Facility (ISPF) application settings and added support for users changing their z/OS password or passphrase.
  • Enhanced z/OSMF desktop editor. Adds linkable URLs to data set names and z/OS File System (zFS) files, and can now be used to view diagnostic data with support from the z/OSMF Incident Log application.
  • Enhanced Integrated Cryptographic Service Facility (ICSF). Enhancements include a new method for encrypting a Data Encryption Standard (DES) secure key token and new and updated utilities to migrate existing keys to a new wrapping method.
  • 64-bit support for z/OS UNIX® memory-map service. Support is extended for applications using the z/OS UNIX or POSIX memory-map services to enable the use of 64-bit storage and map files of lengths greater than 2 GB.
  • Object Access Method (OAM) cloud and additional backup enhancements. Additional backup enhancements are available. A cloud tier is added to the OAM storage hierarchy.

Description

Top rule

BCPii

z/OS BCPii provides a powerful way for z/OS applications to automate and control the operations of Z hardware in multiple languages, including REXX. A new z/OS BCPii API named HWIREST is being introduced for the z15 that enables applications to access many previously unavailable attributes of the z15, including central processor complex (CPC) storage, storage allocated for a logical partition (LPAR), CPC environmentals such as exhaust air temperature and dew points, and detailed information about processors and their assignments to an LPAR. BCPii HWIREST is an interface designed to act more as a passthrough interface to the z15 hardware APIs and machine information. As such, it is intended to surface future attributes that might become available in a new hardware firmware level or machine, without requiring a corresponding z/OS BCPii software update. This new interface is in addition to the existing BCPii services and requires exploiting software to explicitly request the new function.

With the PTF for APAR OA60351, this enhancement is available for z/OS V2.4 and later. It requires a z15, SE 2.15.0 with MCL P46598.370, Bundle S38 or higher, and HMC 2.15.0 with MCL P46686.001, Bundle H25 or higher.

TFP ease of use

To reduce the effort of reporting on TFP solutions, a new system parameter named SOLUT= is added to the system parameter member IEASYSxx. Customers can indicate in the z/OS configuration of a system that it is running with a qualified TFP solution. z/OS reports this information in SMF 89 records. When used with SCRT 28.2.0, clients are no longer required to specify the TFP solution ID in SCRT CONTAINER control statements. Instead, SCRT captures the solution ID from the SMF data and automatically applies it to the system.

This is designed to be an easier and less error-prone alternative to defining TFP solutions with SCRT control statements. With the PTF for APAR OA60198, this function is available for z/OS V2.3 and later. SCRT 28.2.0, or later, is required to exploit the information provided by the new system parameter and is available with the PTF for APAR OA60919 for z/OS V2.3 and later.

z/OSMF enhancements

  • The z/OSMF ISPF application, which renders ISPF applications in a browser instead of requiring a 3270 emulator, is enhanced to add a global settings configuration. This is intended to improve the user experience by providing system-wide defaults for the ISPF application settings rather than requiring each user to configure those values. The setting values of the z/OSMF ISPF application also can be captured in a file and used by an administrator to set up other systems’ global configurations. With the PTF for APAR PH34102, this support is available for V2.3 and later.
  • The z/OSMF desktop editor is enhanced to highlight data set names and zFS file paths as hot-linkable URLs. A user can open the referenced data set or a zFS file from the z/OSMF desktop editor simply by clicking on the link. With the PTF for APAR PH34912, this function is available on V2.4 and later.
  • The z/OSMF Incident Log application adds support for viewing diagnostic data using the z/OSMF desktop editor application. This standardizes the user experience using a more native browser look and feel. Previously, viewing the diagnostic data was performed only using the z/OSMF ISPF application. With the PTF for APAR PH34912, this capability is available for V2.4 and later.
  • A new REST API has been added to support changing a user’s z/OS password or passphrase. With the PTF for APAR PH34912, this function is available for V2.4 and later.

ICSF enhancement

A new method for encrypting a DES secure key token is introduced. This is the first proprietary Triple DES (TDES) key token (also known as a key block) to be independently reviewed and confirmed to be equivalent to the standards of Payment Card Industry (PCI) Security Standards Council (SSC) PIN® Security key block requirements as updated September 30, 2020. The new key block is backward compatible with existing applications, can be stored in the Cryptographic Key Data Set (CKDS), and introduces a new wrapping method called WRAPENH3. The wrapping method controls the cryptographic algorithms used to encrypt the clear-key material within the boundary of the coprocessor, resulting in what is known as a "secure key" from an ICSF perspective.

ICSF offers a utility that can be used to migrate all existing TDES secure keys in a CKDS to the new wrapping method, or it can be done on a key-by-key basis using updated callable services. In addition, a new SAF resource provides a way to override existing applications such that wherever a wrapping method is specified or defaulted, the wrapping method is automatically updated to WRAPENH3.

With the PTF for APAR OA60318, these capabilities are available for V2.2 and later.

z/OS UNIX and POSIX memory-map 64-bit support

Applications using the z/OS UNIX or POSIX memory-map service can now use 64-bit storage and map files of lengths greater than 2 GB. This enhancement helps alleviate below-the-bar memory constraints by enabling applications to use above-the-bar storage for large memory-mapped files. In addition, this new support is designed to improve application performance and simplify data access by facilitating access to large amounts of data at once. With the PTFs for APARs OA60306 and PH32235, this support is available for z/OS V2.4 and later.

OAM cloud and additional backup enhancements

With the PTF for APAR OA55700 for z/OS V2.3 and later, a cloud tier is added to the OAM storage hierarchy. With the OAM cloud tier support, the primary copy of an OAM object can be managed and stored as an object to a public, private, or hybrid cloud infrastructure that supports the S3 API. However, OAM-managed backup copies continue to be supported as they are today to removable media, typically virtual or physical tape. With the PTF for APAR OA59615 for z/OS V2.3 and later, an OAM-managed backup copy of a primary object is additionally supported in the cloud and in a file system (zFS or NFS). OAM continues to support up to two backup copies of an OAM object.

Section 508 of the US Rehabilitation Act

z/OS V2.4 is capable as of the planned availability date, when used in accordance with associated IBM documentation, of satisfying the applicable standards, including the Worldwide Consortium Web Content Accessibility Guidelines, European Standard EN 301 349, and US Section 508, provided that any assistive technology used with the product properly interoperates with it. An Accessibility Conformance Statement can be requested on the Product accessibility information website.

Statement of good security practices

Top rule

IT system security involves protecting systems and information through prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a lawful, comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective.

Important: IBM does not warrant that any systems, products, or services are immune from, or will make your enterprise immune from, the malicious or illegal conduct of any party.
