This newly updated second edition of Michael A. Raithel's esteemed Tuning SAS Applications in the MVS Environment is the definitive book for tuning SAS applications that run on mainframe computers under the MVS, OS/390, and z/OS operating systems. Tuning SAS Applications in the OS/390 and z/OS Environments details the many tools and methodologies SAS programmers can use to reduce computer-processing overhead, thus making their applications perform better and reducing computer charge-back costs. SAS programmers experienced in other operating environments, as well as newer SAS users, will gain knowledge of OS/390 system processes, performance measures, and operating system features. In addition, key OS/390 concepts are highlighted, including the three types of work that run on OS/390; OS/390 memory management; and hiperspaces. New features in this second edition include: the many Version 8 enhancements to SAS running under OS/390. new sources of performance information such as the SAS SMF exit. a detailed explanation of index centiles--what they are and how they can be used. New information explains how SAS programmers can specify that a particular index be used or that no index be used. You will also find updated information on exploiting indexes through WHERE clauses and BY statements. updated information on efficiently processing large data sets stored on tape. details on the new SASFILE statement. Programmers can learn how to exploit the SASFILE statement to hold an entire SAS data set in memory and avoid costly I/O's. new features of the CONTENTS procedure that provide performance information. If you are a new or experienced SAS user trying to learn more about OS/390 concepts or searching for great tuning tips, this book was written for you!
