SDSF

__NOTOC__Using the various panels, pop-up windows, and pull-downs the System Display and Search Facility allows an IBM z/OS mainframe user to view the status of various resources like batch jobs, started tasks (long running address spaces analogous to unix daemons) or z/OS UNIX processes that have been started by the operator or submitted by the user.

Some of the options available are:

* LOG: To see the current log of system activity.
* DA: Displays ACTIVE (running) processes.
* I: Input Queue - shows jobs waiting execution.
* H: Jobs on HOLD - either waiting to be released into Input or Output or actual copies of job JCL (Job Control Language) or previously executed jobs.
* ST: Displays current status of all jobs
* PR: Displays printers.
* INIT: Displays Initiators (areas where jobs execute or run).
* O: Output Queue
* LINE: Network Job Entry (NJE) Lines
* SR: System Requests
* MAS: Members in a MAS (Multiple Access Spool)
* JC: Job Classes
* PS: z/OS UNIX Processes
* RES: WLM (WorkLoad Manager) Resources
* ENC: Enclaves
* SE: Scheduling Environments
* PUN: Punches
* RDR: Readers
* NODE: NJE (Network Job Entry) Nodes
* SO: Spool offload
* SP: Spool volumes
* RM: Resource monitor
* CK: Health checker
* ULOG: User session log

Prior to z/OS Release 10, SDSF was only supported for use with JES2 and not JES3, although there were ISV products available with similar functionality for JES3. At and beyond z/OS Release 10 JES3 is now fully supported, with some new commands (JDS and ODS) to display the data/sets and job output for JES3 jobs.

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.

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.
