operations, availability, and manageability through innovative self-learning, self-
managing, and self-optimization capabilities.
z/OS is designed to learn heuristically from its own environment to anticipate and
report on system abnormalities, predicting problems before they occur with its
innovative Predictive Failure Analysis (PFA) capability. For example, PFA can be used
during application testing to identify previously unknown potential problem areas
before the application is put into production or can be used in production systems to
help identify issues before they become serious.
In the event of an issue, z/OS can help you be responsive with real-time decision
making assistance. A new z/OS Run Time Diagnostics function is planned to analyze
key indicators on a running system quickly, and help identify the root causes of
system degradations. The Run Time Diagnostics function is anticipated to run in as
little as one minute, to return results quickly enough to help you choose between
alternative corrective actions and help you maintain high levels of system and
application availability.
In some situations, your operations may be so critical that human analysis and
intervention may not be fast enough, and the system must have the ability to act
quickly and decisively. In a Parallel Sysplex®, the GRS and XCF components are
planned to have the ability to automatically initiate actions to preserve sysplex
availability so as to help reduce the incidence of sysplex-wide problems that can
result from unresponsive critical components. The system can take action to fence,
or stop and start critical members automatically, preventing small problems from
becoming major problems.
And in still other situations, z/OS keeps your system available automatically and
transparently. z/OS will be designed to avoid 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.
z/OS V1.12 can save you time and money. This ability to discover, decide, and
resolve issues automatically and in a fraction of the time can keep your organization
nimble and responsive to changing business needs.
