SDSF

<h2 id="history">History</h2>
<p>When it was a <a href="/facts/Third-party_software_component/NFlWUV95">field-developed</a> program offering, SDSF was known as the <a href="/facts/Spooling/fPbanPPu">SPOOL</a> Display and Search Facility The word <i>SPOOL</i> was changed to <i>System</i> when it became a <a href="/facts/Software_as_a_Product/7jgkdy9C">program product</a> in the late 1980s.
</p><p>With <a href="/facts/Z%2fOS/amLCAlgV">z/OS</a> Release 1.9, SDSF supports a <a href="/facts/REXX/hAzh6FeR">REXX</a> interface, allowing batch programs to use SDSF facilities. This support includes stem variables containing SDSF-originated information.
</p><p>Prior to z/OS Release 1.10, SDSF was only supported for use with <a href="/facts/JES2/IXjXWmQF">JES2</a> and not <a href="/facts/JES3/IXjXWmQF">JES3</a>, although <a href="/facts/Independent_software_vendor/Vkt3oRBJ">ISV</a> products from Phoenix Software International and Tone Software were available with similar functionality for JES3. At and beyond z/OS Release 1.10, SDSF fully supports JES3, including some new commands (JDS and ODS) to display the data/sets and job output for JES3 jobs.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>
</p><p>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 open logs from Rexx and Java-programmed environments.

<p>SDSF is organized as a collection of panels where each panel displays information about a specific aspect of the mainframe's operations. These panels are currently provided:
</p>
<ul><li>LOG: To see the current log of system activity.</li>
<li>DA: "Display Active users/jobs" or running processes.</li>
<li>I: Input Queue - shows jobs waiting execution.</li>
<li>H: Jobs on HOLD - either waiting to be released into Input or Output or actual copies of job JCL (<a href="/facts/Job_Control_Language/UCpfhoe4">Job Control Language</a>) or previously executed jobs.</li>
<li>ST: Displays current status of all jobs. Job list can be filtered using the PRE primary command.</li>
<li>PR: Displays printers.</li>
<li>INIT: Displays Initiators (areas where jobs execute or run).</li>
<li>O: Output Queue</li>
<li>LINE: Network Job Entry (NJE) Lines</li>
<li>SR: System Requests</li>
<li>MAS: Members in a MAS (Multiple Access Spool)</li>
<li>JC: Job Classes</li>
<li>PS: z/OS UNIX Processes</li>
<li>RES: WLM ( Workload Manager) Resources</li>
<li>ENC: Enclaves</li>
<li>SE: Scheduling Environments</li>
<li>PUN: Punches</li>
<li>RDR: Readers</li>
<li>NODE: NJE (Network Job Entry) Nodes</li>
<li>SO: Spool offload</li>
<li>SP: Spool volumes</li>
<li>RM: Resource monitor</li>
<li>CK: Health checker</li>
<li>ULOG: User session log</li></ul>
<p>On the ST panel, SDSF supports the following commands for each batch job. These commands are translated into a JES2 or JES3 command that performs the desired function:
</p>
<ul><li>C: Cancel a running job</li>
<li>S: Select job (view only)</li>
<li>SE: Select edit job (view in edit mode)</li>
<li>SJ: Show job (view original JCL of the job)</li>
<li>P: Purge a job (remove entirely)</li></ul>
