(A dataset on z/OS is equivalent to a file on other operating systems.) In the main SPUFI screen one specifies an input dataset and an output dataset; these can be specified once and then reused repeatedly. When the user moves on from the main screen, the standard ISPF editor is opened on the input dataset. At this point the user can enter the ...
Currently, 32 IBM mainframes may share the TPF database; if such a system were in operation, it would be called 32-way loosely coupled. The simplest loosely coupled system would be two IBM mainframes sharing one DASD (Direct Access Storage Device). In this case, the control program would be equally loaded into memory and each program or record ...
The name DB2 (IBM Database 2), was first given to the Database Management System or DBMS in 1983 when IBM released DB2 on its MVS mainframe platform. [12] For some years DB2, as a full-function DBMS, was exclusively available on IBM mainframes. Later, IBM brought DB2 to other platforms, including OS/2, UNIX, and MS Windows servers, and then ...
The S/390 Integrated Server (aka S/390 IS) is a mainframe housed in a comparatively small case (HxWxD are 82 x 52 x 111 cm). It became available from November 1998. It is intended for customers who do not require the I/O bandwidth and performance of the S/390 Multiprise 3000 (which has the same size). Only 256 MB of ECC Memory and a single CMOS ...
The OMEGAMON product family provides analysis of IBM mainframe operating systems such as z/OS and z/VM and various sub-systems such as CICS, DB2 and IMS. There are 9 products in the IBM Tivoli OMEGAMON family: IBM Tivoli OMEGAMON XE for z/OS V5; IBM Tivoli OMEGAMON XE for CICS on z/OS V5; IBM Tivoli OMEGAMON XE for IMS on z/OS V5
An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions.
Hercules is a computer emulator allowing software written for IBM mainframe computers (System/370, System/390, and zSeries/System z) and for plug compatible mainframes (such as Amdahl machines) to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems ...
FETCH ABSOLUTE n FROM cursor_name FETCH RELATIVE n FROM cursor_name; Scrollable cursors can potentially access the same row in the result set multiple times. Thus, data modifications (insert, update, delete operations) from other transactions could affect the result set. A cursor can be SENSITIVE or INSENSITIVE to such data modifications.
