Recent Enhancements

The SDSF task of z/OSMF simplifies management of your z/OS sysplex. The following illustration shows one of the views of jobs. You can also work with job data sets and checks, as well as issue system commands.


With z/OS V2R2, SDSF adds the following new function:

  • A Job Step panel lets you work with the steps for a job. In addition, a column for job step is added to the Job Data Set panel.
  • A new Job Group panel shows information about JES2 job groups, that is, groups of jobs that are related with a relationship defined through JCL. A new Job Dependency panel shows dependencies between jobs in a group. In addition, columns related to job groups are added to the Input Queue and Status panels.
  • A SNAPSHOT command lets you display the data from a tabular panel (such as DA, or ST) in a browse or edit session. You might then use SDSF's Print function to print the data, or ISPF functions to copy it to a data set.
  • You can run a REXX exec against a row on a tabular panel, using an action character.
  • An RGEN command generates a REXX exec for the current panel and displays it with ISPF Edit.
  • SDSF now allows some processing to be performed on a IBM z Integrated Information Processor (zIIP), if one has been configured.
  • The System Command Extension pop-up now allows you to supply comments for commands and assign commands to groups. The number of commands saved between sessions is increased. Management of saved commands is enhanced.
  • You can issue action characters and overtype fields from the command line.
  • The HASPINDX data set is no longer used.
  • SDSF's REXX support now includes a COMPACT option, which results in panel data being returned in the SDSFROW stem variable, rather than in stem variables for each column.

With z/OS V2R1, SDSF adds the following new function:

  • Browsing directly with REXX. A new ISFBROWSE host command and new special variables provide support for browsing job output, check output and the system log using a REXX exec. This provides an alternative to the previously available support, which allowed you to allocate the data sets and then use EXECIO or a similar utility 
  • Sorting on up to 10 columns. Tabular panels now allow sorting on up to 10 columns, and you can now display the full set of sort and filter criteria.
  • Filtering using symbols. You can use system symbols (both static and dynamic) with filtering. The Filter pop-up lets you display a list of the current symbols and their values.
  • Simplified printing. When printing to SYSOUT, you can request that the SYSOUT use the attributes of the source. You can also request that SDSF use the record format of the output data set to determine how to handle carriage control for all printing,
  • Tracing SDSF security. The SET SECTRACE command helps you understand and diagnose SDSF security (SAF or ISFPARMS).
  • Support for 64-bit addressing. SDSF supports 64-bit addressing, which allows SDSF panels to handle very large numbers of rows.
  • Working with long JES2 job class names. SDSF supports the JES2 enhancement for job class names of up to 8 characters.
  • Customizing SDSF. You can use commands and custom properties to define how SDSF names the extended console it activates on your behalf, whether SDSF displays duplicate SYSOUT data sets when you browse or print job output, which CPU-busy value (MVS or LPAR) is used to normalize the CPU% column on the DA panel, and to set the scope of the CK, DA, ENC and PS panels to the JESPLEX rather than the sysplex.

With z/OS V1R13, SDSF adds the following new function:

  • Completion of simplified sysplex support.  With enhancements in this release, these device panels are sysplex-wide by default, without the need for WebSphere MQ, in all supported environments: LI, NO, PR, PUN, RDR and SO. The INIT panel is sysplex-wide by default when all systems are V1R12 or higher.
  • Completion of support for the JES3 environment. These panels are now available for JES3: INIT, LI, NO, PUN, RDR, H and O. A new J0 (Job 0) panel is added.
  • New panels for JES networking. A Network Connect (NC) panel shows information about JES networking connections to an adjacent node.  A Network Server (NS) panel shows information about JES server-type networking devices on the node.
  • Accessing the OPERLOG with REXX and the Java programming language. You can now access the sysplex-wide system log with REXX execs and Java programs.
  • Color for the OPERLOG. Messages are displayed on the OPERLOG panel with the color that was assigned to them when they were issued. You can customize the colors with the SET SCREEN command.
  • Cursor-sensitive sort. You can sort on a column by placing the cursor on the title and pressing Enter. Other selectable options now use ISPF point-and-shoot, meaning that you can take an action by tabbing to a field and pressing Enter.
