Displaying dump options or dump data set status

Use the DISPLAY DUMP command to determine:
  • Status and availability of pre- and automatically allocated dump data sets
  • What dump mode and options are currently in effect
  • The title and error-related data for pre- and automatically allocated dump data sets
D {DUMP} 
 
D {DUMP},{{STATUS|ST|S}                                                }
  {D   }                                                             
         {{OPTIONS|O}                                                  }
                                                                     
         {{TITLE|T     }{,AUTODSN={aaa|ALL}                           }}
         {{ERRDATA|ER|E}{                                             }}
                        {,DSN={ALL|(ALL)                    }         }
                              {nn|(nn[,nn]...)              }         
                              {nn-nn|(nn-nn[,nn-nn]...)     }         
                              {(nn[,nn]...,nn-nn[,nn-nn]...)}         
                                                              
                        {,DUMPID={xxx|(yyy[,zzz]...)                 }}
                                 {aaa-bbb|(aaa-bbb[,ccc-ddd]...)     }
                                 {(yyy[,zzz]...,aaa-bbb[,ccc-ddd]...)}

   [,L={a|name|name-a}]
DUMP or D
The system is to display dump information.
STATUS or ST or S
The system is to display (message IEE852I) a summary of:
  • Which SYS1.DUMP data sets are available and which are full
  • How many dumps are captured in virtual storage and how much storage they occupy
  • How much virtual storage is available for capturing additional dumps
  • The status of automatic dump data set allocation
  • What resources are defined for automatic dump data set allocation
  • The naming convention currently in effect for automatically allocated dump data sets
OPTIONS or O
The system is to display:
  • Coupling facility system failure dumping options
  • Dump mode and options in effect for dump types:
    • SDUMP
    • SYSUDUMP
    • SYSMDUMP
    • SYSABEND
TITLE or T
The system is to display (message IEE853I) the dump data set name, title, and time of the dump for the captured dumps or dumps written to pre- or automatically allocated dump data sets as requested by the AUTODSN=, DSN=, and DUMPID parameters.
ERRDATA or ER or E
The system is to display (message IEE854I) error data for:
  • Full direct access dump data sets that you specify in DSN=
  • Automatically allocated dump data sets specified in AUTODSN=
  • Captured dumps that you specify on the DUMPID parameter.
The error data for each full data set includes:
  • Dump title
  • Data set names for automatically allocated dump data sets
  • Time of dump
  • Error id, which includes the sequence number, the processor id, the ASID of the failing task, and the time stamp
  • Abend code
  • Reason code
  • Module name
  • Failing CSECT name
  • Error PSW
  • Translation exception address
  • Abending program address
  • Recovery routine address
  • Registers at time of error

The SDWA furnishes most of the data that appears in the display caused by the DISPLAY DUMP,ERRDATA command. This means that if MVS/ESA is not in recovery mode, the display contains only the data set name, title, and time of the dump.

AUTODSN={aaa or ALL}
The system is to display the requested dump information about the dump data sets that were most recently allocated automatically. Only those dump data sets allocated since the last IPL will be presented. Dump data sets created in a previous IPL will not be displayed by this command.
aaa
Specifies the number of data sets for which information is displayed. aaa must have a value from 1 to 100.
ALL
The system displays information for all dump data sets that were automatically allocated to a maximum of one hundred.

AUTODSN=, DSN=, and DUMPID= are mutually exclusive.

DSN={ALL or nn}
The system is to display dump information about all direct access dump data sets or specific pre-allocated direct access dump data sets. For DSN= you can specify:
  • All data sets
  • One or more single data sets
  • One or more ranges of data sets

For specific data sets or ranges, nn must have a value from 00 to 99. When you specify a range of data sets, the first nn in the range must be less than or equal to the second nn.

If you specify DSN=ALL, then the system also displays information about the one dump data set that was most recently allocated automatically.

DSN=, AUTODSN=, and DUMPID= are mutually exclusive.

DUMPID=xxx or aaa- ddd
The system is to display the dump information about specific captured dumps waiting to be written to dump data sets, as denoted by the three decimal digit DUMPID. You can specify for DUMPID= one or more single captured dump identifiers and/or one or more ranges of captured dump identifiers. For any of these specifications, the value must be in the range of 000 to 999. When you specify a range of captured dump identifiers, the first identifier must be less than the second identifier. Multiple identifiers or ranges must be enclosed in parentheses and separated by commas.

DSN=, AUTODSN=, and DUMPID= are mutually exclusive.

L=a, name, or name-a
Specifies the display area (a), console name (name), or both (name-a) where the display is to appear.

If you omit this operand, the display is presented in the first available display area or the message area of the console through which you enter the command.

Example 1:

To check the full or available status of all defined SYS1.DUMP data sets on both direct access and tape devices, enter: 
D DUMP

Example 2:

To display the dump title for direct access dump data sets 1, 5, 6, 7, 8, 9, 10, and 90, enter: 
D D,T,DSN=(01,05-10,90)

If any of these data sets are empty or undefined, the system tells you that dump data is not available for them.

Example 3:

To display error data for all full direct access dump data sets and the most recent automatically allocated dump data set, enter: 
D D,ER,DSN=ALL

Example 4:

To display error data, if any, for direct access dump data sets 1-21, enter: 
D D,ER,DSN=(01-21)

If any of these data sets are empty or undefined, the system tells you that dump data is not available for them.

Example 5:

To see the dump modes and dump options in effect for each dump type, enter: 
D D,O

Example 6:

To DISPLAY the error data for captured dump 123, enter: 
D D,ER,DUMPID=123

Example 7:

To DISPLAY the titles of captured dumps 123 and 456, enter: 
D D,T,DUMPID=123,456

Example 8:

To DISPLAY the titles of all, or the one hundred most recent, automatically allocated dump data sets, enter: 
D D,T,AUTODSN=ALL
