The System Display and Search Facility (SDSF) feature of IBM mainframes running z/OS allows users and administrators to be able to view and control various aspects of the mainframe's operation and system resources. Batch job output, status of running Unix processes, system information, workload scheduling,External device monitoring such as printers,initiators . SDSF is primarily used to access the batch and system log files and dumps. == History == SDSF was originally known as SPOOL Display and Search Facility - when it was a field-developed program offering. The word ''SPOOL'' was changed to ''System'' when it became a program product in the late 1980s. With z/OS Release 9 SDSF supports a REXX interface, allowing batch programs to use SDSF facilities. This support includes stem variables containing SDSF-originated information. Prior to z/OS Release 10, SDSF was only supported for use with JES2 and not JES3, although ISV products from Phoenix Software International and Tone Software are available with similar functionality for JES3. At and beyond z/OS Release 10, SDSF now fully supports JES3, with some new commands (JDS and ODS) to display the data/sets and job output for JES3 jobs.〔 〕 With the release of z/OS V1R13, SDSF came packed with some interesting features like cursor sensitive sort or point and shoot sort and extensive support for oper logs from Rexx and Java programmed environments. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「SDSF」の詳細全文を読む スポンサード リンク
