IBM® previews z/OS® Version 1.12. With this latest release of z/OS, IBM heralds
a new area of smart operating systems by creating an environment that can
proactively work for you to help promote improved operations, availability,
manageability, and security through innovative self-learning, self-managing, and
self-optimization capabilities. Enhancements include:
• Predicting problems - z/OS Predictive Failure Analysis® (PFA) is planned to
monitor the rate at which SMF records are generated. When the rate is abnormally
high for a particular system, the system will be designed to issue an alert to warn
you of a potential problem, potentially avoiding an outage.
• Real-time decision making in the event of a system problem - A new z/OS Run
Time Diagnostics function is planned to help you quickly identify possible problems
in as little as one minute.
• Automatic partitioning - GRS and XCF components are planned to automatically
initiate actions to preserve sysplex availability to help reduce the incidence of
sysplex-wide problems that can result from unresponsive critical components.
• Avoiding data fragmentation and planned outages for data reorganizations - With
the new CA (Control Area) Reclaim capability, applications that use VSAM key-
sequenced data sets (KSDSs) can benefit from improved performance, minimized
space utilization, and improved application availability though the avoidance of
planned outages that used to be required to defragment and reorganize this data.
• Workload driven provisioning - Capacity Provisioning is planned to use CICS® and
IMS
monitoring data to determine if additional resources are needed to meet
TM
service-level requirements for these workloads.
• Storage management and scaling - Extended Address Volumes are planned to
support additional data set types, including sequential (both basic and large) data
sets, partitioned (PDS/PDSE) data sets, catalogs, and BDAM data sets. Overall,
EAV helps you relieve storage constraints as well as simplify storage management
by providing the ability to manage fewer, large volumes.
• Advanced cryptography - z/OS is planned to support Elliptic Curve Cryptography
(ECC), which is regarded by the U.S. National Security Agency (NSA) as a faster
algorithm that requires a smaller key than RSA cryptography. This function is
embedded into z/OS and is not a separately chargeable product.

decisions - that can benefit your business. IBM previews z/OS V1.12. With this
