Display Dump

Purpose:  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},{{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-dd]...)}}}

[,L={a|cc|cca|name|name-a}]

Parameters

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:

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

ne 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, cc, cca, name, or name-a

Specifies the display area (a), console (cc), both (cca), console name (name), or both (name-a) where the display will be presented. For cc, you must specify a decimal number from 1 to 99.

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 (unless routing instructions are in effect; see the MSGRT command later in this chapter).
