Abstract: IBM z/OS V2.1 can help you innovate with data ready, cloud ready and security ready capabilities to help you deliver smarter, more efficient computing. And new IBM z/OSMF V2.1 management capabilities continue to simplify administration and operations, extending the value of z/OSMF.

Enhancements for z/OS V2.1 are designed to help you achieve the scale and availability needed for cloud, deliver a superior data serving environment, and secure your mission-critical assets. For instance, z/OS V2.1 is designed to help you:
  • Provide support for zEDC, designed to compress data with low CPU overhead and at low latency.
  • Support for Shared Memory Communications-Remote Direct Memory Access (SMC-R), can help you move data quickly between z/OS images on the same CPC or a different CPC, and is designed to work without requiring changes to applications.
  • Further optimize data placement with significant enhancements to policy-based storage tiering.
  • Support designed to help you make batch DB2 updates with less performance impact in a Parallel Sysplex when DB2 data is cached in a coupling facility.
  • Provide a top-down perspective on performance and capacity planning efforts across zEnterprise ensembles with RMFTM support for new SMF records for the LinuxTM on System z , and for the Linux on System x and AIX operating systems running on zBX blades. RMF V2.1 also adds support for WindowsTM Server running on zBX blades.
  • Extend existing batch runtime environment support for COBOL-based applications to interoperate with PL/I programs in addition to JAVATM programs, all with shared DB2 with transactional integrity, and extended support to encompass DFSMStvs processing for VSAM record-level sharing data sets. These enhancements are intended to provide flexibility in application development and provide modern programming models to help you extend business applications.
  • Reduce batch run times by having DFSMShsm-migrated data sets allocated by batch jobs recalled in parallel, in order to reduce overall elapsed recall times.
  • Simplify I/O configuration tasks with improvements for z/OS FICON Discovery and Auto Configuration (zDAC), which provides improved support for installations with less-complex I/O configurations.
  • Provide for RACF , PKI, and SSL in EP11 mode to support secure key PKCS #11 standard in addition to CCA and accelerator modes of operation.
  • Improve interoperability, with support for Japanese Industrial Standards for Extended UNIXTM Code and programming services that meet the Unicode 6.0 standard, among others, better enabling you to serve new customers.
  • Exploit available fonts, with fonts included as a new base element of z/OS to give you capabilities you need for print in a global marketplace.

z/OSMF V2.1 introduces capabilities designed to help you manage your z/OS environment more effectively and in a more consistent manner, helping you improve overall quality:
  • Reduce resource requirements with use of the Liberty profile in IBM WebSphere Application Server for z/OS , V8.5 in z/OSMF V2.1.
  • Manage your software service levels with new reporting and display capabilities, to help you determine the currency of your installed system software portfolio at a glance.
  • Use a new workflow application infrastructure along with roles-based notifications intended to help with simplification of configuration tasks.
  • Manage On/Off Capacity on Demand in a more intuitive way.

These select highlights of z/OS V2.1 contribute to the foundation of a highly secure, available, and scalable enterprise infrastructure for efficiently running business critical applications. Some new IBM solutions well suited for this environment include:
  • IBM Smarter Analytics Anti-Fraud Infrastructure to help banking, insurance, healthcare, and other customers deploy real-time, prepayment fraud-detection capabilities solutions and integrate these functions into operational systems
  • IBM Smarter Infrastructure for Social Services, to provide a leading and highly flexible solution for end-to-end social program service delivery, ensuring privacy with a single source of secure data.
  • IBM Enterprise Key Management Foundation, a comprehensive highly secure key management system, which is ideal for banks and payment card processors that must comply with industry standards and manage keys and certificates.
