$D SSI(nnn)

Function

To display information about a subsystem interface (SSI) function. This information is helpful in diagnosing a JES2 problem. This information includes the virtual address of an SSI entry point in storage, a short description of the SSI function, and whether tracing is active or not.

This command has parameters you can use as a filtering technique to limit the type of information to search, or the amount of information to display. See Using filtering to control and display information for additional information.

Parameters

ADDRess: Displays the hexadecimal address of the SSI function routine in storage.
DESC: Displays a short description of the SSI function.
MODULE: Displays the assembly module containing the SSI function routine.
SSI({nnn|*}): Specifies the SSI function number (1-256). Specify the SSI number to display information for a specific SSI function, or specify an asterisk (*) to display information for all SSI functions. Information only for SSI function routines which are defined will be displayed.
TRace[=No|Yes]: Displays whether tracing is active for this SSI function. You can specify the TRACE parameter without a keyword, or you can specify a trace keyword (Y or N) to request information about all SSI functions where tracing has been activated (Y) or no tracing is active (N).

Authority Required

This command requires display authority. The description of the $T RDRnn command explains how to ensure that the authority of the appropriate MVS™ system command group is assigned.

This command requires read security access authority. For a description of assigning command input authority, see z/OS JES2 Initialization and Tuning Guide, SA32-0991.

Scope

Single member. The response to this command will be a display of information about this member only. You might want to use this command to get information about all members in the MAS. To do so, you can use the MVS ROUTE *ALL command to issue this command to all active members (if the JES2 command character is the same on all members). See z/OS MVS System Commands, SA38-0666 for more information on using the ROUTE *ALL command.

Messages

The $HASP648 message displays requested information about the SSI function.

Example
