  • Paper SAS1715-2015 More Data, Less Chatter: Improving Performance on Z/OS Via IBM Zhpf Lewis King and Fred Forst, SAS Institute Inc., Cary, NC
    Paper SAS1715-2015 More Data, Less Chatter: Improving Performance on z/OS via IBM zHPF Lewis King and Fred Forst, SAS Institute Inc., Cary, NC ABSTRACT This paper describes how we reduced elapsed time for the third maintenance release for SAS® 9.4 by as much as 22% by using the High Performance FICON for IBM System z (zHPF) facility to perform I/O for SAS® files on IBM mainframe systems. The paper details the performance improvements, internal testing to quantify improvements, and the customer actions needed to enable zHPF on their system. The benefits of zHPF are discussed within the larger context of other techniques that a customer can use to accelerate processing of SAS files. INTRODUCTION To achieve optimum input/output (I/O) performance, the SAS product on the IBM mainframe operating system z/OS dynamically generates low-level I/O instructions (in the form of channel programs) to process SAS direct access bound libraries. For the types of I/O operations required by SAS processing, the channel programs generated by SAS provide a higher rate of throughput (amount of data per unit of elapsed time) than what is possible with standard IBM DFSMS access methods. In October 2008, IBM introduced High Performance FICON for System z (zHPF), which is a set of I/O architecture improvements that enable higher rates of I/O throughput (IBM 2015a). Over the next several years, zHPF capabilities were extended (IBM 2015a), and in October 2012, IBM announced functionality that enables programs like SAS to execute channel programs that take advantage of the zHPF feature (IBM 2015b).

  • Using Data Sets
    Introducción al Sistemas Operativo z/OS Introducción a los Data Sets USING DATA SETS José Luis Calva Martínez Email: [email protected] [email protected] INTRODUCTION In working with the z/OS operating system, you must understand data sets, the files that contain programs and data. The characteristics of traditional z/OS data sets differ considerably from the file systems used in UNIX and PC systems. To make matters even more interesting, you can also create UNIX file systems on z/OS, with the common characteristics of UNIX systems. A data set is a collection of logically related data; it can be a source program, a library of programs, or a file of data records used by a processing program. DtDataset recordsarethe bibasicunit of ifinforma tion used bby a processing program. José Luis Calva 1 Introducción al Sistemas Operativo z/OS Introducción a los Data Sets WHAT IS A DATA SET? Nearly all work in the system involves data input or data output. In a mainframe system, the channel subsystem manages the use of I/O devices, such as disks, tapes, and printers, while z/OS associates the data for a given task with a device. z/OS manages data by means of data sets. The term data set refers to a file that contains one or more records. Any named group of records is called a data set. Data sets can hold information such as medical records or insurance records, to be used by a program running on the system. Data sets are also used to store information needed by applications or the operating system itself, such as source programs, macro libraries, or system variables or parameters.
