removing the need to copy message buffers and associated storage structures
from 64-bit addressable virtual storage to 31-bit storage and back.
• The DFSMShsm DUMP function used to copy source disk volumes to a target tape
volume is planned to be enhanced. The dump stacking function will be designed
to allow up to 255 source volumes to be dumped to a single tape volume, up from
the prior limit of 99. This is intended to help you take better advantage of large-
capacity tape cartridges.
• z/OS Communications Server TN3270E Telnet server plans to provide access
method control block (ACB) sharing for logical units (LUs) as a way to help reduce
ECSA usage. Prior to z/OS V1.12 Communications Server every Telnet LU name
opened its own ACB to VTAM®. You can code a new SHAREACB statement to allow
multiple Telnet LUs to share a single ACB, which reduces the overall amount of
ECSA (and Telnet private) storage allocated to support Telnet sessions.
• Standalone Dump is designed to support extended format dump data sets in the
extended addressing space (EAS) on Extended Address Volumes (EAVs).
• Superzap (AMASPZAP) is planned to support dumping and altering data for
sequential, partitioned, and direct data sets placed in EAS on EAVs.
Application integration
The platform's classic strengths of availability, security, reliability, scalability, and
management have made the mainframe the de facto standard for data serving and
OLTP. It is logical to extend z/OS to Business Intelligence and Data Warehousing
solutions as well, where large amounts of reports can be generated in a timely
manner using source data -- all with a simplified reconciliation and restatement
process. But it is also logical to deploy new or extend existing applications that
leverage data on z/OS.
What sets z/OS apart is the ability to operate both new and existing applications
within the same system, and in close proximity to your corporate data residing on z/
OS. New applications based on Java, WebSphere Application Server, Perl, PHP, XML,
C/C++, Unicode, HTML, HTTP, SOAP, z/OS UNIX System Services, and other Web
services can operate side by side and integrate with classic applications based on
CICS, IMS, DB2, Enterprise COBOL, Enterprise PL/I, REXX, System REXX, JCL, TSO/
E, ISPF, Assembler, and Metal C. These applications can be colocated with relational
(DB2) and non-relational (IMS) databases as well as record-oriented data. With
such proximity to the data, applications on z/OS have a reduced need for expensive
communications and networking infrastructure and can offer fewer opportunities for
security breaches due to tight integration with traditional z/OS security, audit and
resource access.
Businesses with applications on z/OS understand the value of those applications,
as well as understanding that replacing these systems with standard packages or
other custom-built alternatives is not needed and may, in fact, be unnecessarily
risky. Modernizing z/OS applications can lower costs and drive business agility with
significantly enhanced levels of usability and integration.
• z/OS V1.12 is planned to include the following updates: enhancements to C/C
++ in support of Euro currency, new standard time services, and Unicode; and
enhancements to z/OS XML System services in support of schema extraction and
fragment parsing.
Details on the application integration improvements planned for z/OS V1.12 include:
• SDSF will be designed to make Java classes available, to provide a new means of
accessing SDSF. Classes will be provided for each of the SDSF panels that can be
used by applications to request SDSF functions. This new support is designed to
allow Java-based applications to easily access SDSF.
• SDSF is planned to introduce a new ISFLOG command for SDSF REXX. It is
designed to read the system log and return its records in stem variables, and to
support options to limit the number of records returned and specify start and end
times. This new function will simplify access to the system log for SDSF REXX.
