IBM 890 manual Automation Support, System Services, z/OS Version 1 Release 6 base elements

Applications that can be written to 64-bit virtual storage have signifi cantly larger addressability to data. With z/OS 1.2, assembler programs can obtain virtual storage above 2 GB for storing and manipulating data. This 64-bit support is used by DB2 V8 and other middleware. z/OS 1.6 includes C/C++ support for the development of 64-bit applications, including debug and runtime support. In addition, the Java SDK 1.4.1 is also available with 64-bit support.

Automation Support

z/OS Managed System Infrastructure for Operations (msys for Operations) provides automation for single system and sysplex operations to help simplify operations and improve availability. msys for Operations plays an important role in outage avoidance.

Functions msys for operations provides control and manage both hardware and software resources making fully automated solutions possible. The focus is on simpli- fying complicated operator interaction, detecting failure situations and reacting to them quickly and precisely. This is achieved through panel driven operator dialogs and automated recovery routines that run in the background.

Simplifi ed Confi guration z/OS Managed System Infrastruc- ture for Setup (msys for setup) is the strategic solution for product installation, confi guration and function enable- ment. msys for Setup allows usage of consistent interfaces with wizard-like confi guration dialogs. In z/OS 1.4, the msys for Setup Framework was enhanced to provide multi- user capability and improved multisystem support.

The msys for setup dialogs use defaults and best practices values whenever possible and derive low-level values from answers to high-level questions. After the confi guration param- eters have been specifi ed, msys for Setup can automatically update the system confi guration directly. The user can see in detail what the changes will be before they are made.

Also, with z/OS 1.5 msys for Setup can use the IBM Direc- tory Server, OpenLDAP, on any IBM platform including OpenLDAP on z/OS UNIX® System Services. This can sim- plify the initialization of msys for setup, and can make the Management Directory virtually transparent to the user.

The following functions can be confi gured using msys for Setup: Parallel Sysplex clustering, TCP/IP, UNIX System Service, Language Environment, LDAP, RMF, ISPF, FTP, and DB2 UDB for z/OS V8.
