Symptoms from SVC dumps

Use a DISPLAY DUMP operator command to get the symptoms from SVC dumps in SYS1.DUMPxx data sets on direct access or from SVC dumps that have been captured in virtual storage. The system displays the following symptoms in message IEE854I:

Dump title or a message telling why the title is not available
Error id consisting of a sequence number, the processor id, the ASID for the failing task, and the time stamp
System abend code
User abend code
Reason code
Module name
Failing CSECT name
Program status word (PSW) at the time of the error
Interrupt length code in the system diagnostic work area (SDWA)
Interrupt code in the SDWA
Translation exception address in the SDWA
Address of the failing program in the SDWA
Address of the recovery routine in the SDWA
Registers at the time of the error saved in the SDWA

For example, you can issue DISPLAY DUMP to view various types of symptoms:

To see symptoms from the dump in the SYS1.DUMP03 data set without displaying any automatically allocated data sets, enter:
```
     DISPLAY DUMP,ERRDATA,DSN=03
```
To see symptoms from the most recently automatically allocated dump data set and all pre-allocated dump data sets, enter:
```
     DISPLAY DUMP,ERRDATA
```
or:
```
     DISPLAY DUMP,ERRDATA,DSN=ALL
```
To see symptoms from the last 5 most recently allocated dump data sets, enter:
```
     DISPLAY DUMP,ERRDATA,AUTODSN=5
```
To see symptoms from the captured dump identified by DUMPID=005, enter:
```
     DISPLAY DUMP,ERRDATA,DUMPID=005
```

Using the DISPLAY DUMP,ERRDATA command (see Figure 1) , you can retrieve basic information about the dump without having to format the dump or read through the system log. Message IEE854I displays the error data information, including the PSW at the time of the error, the system abend code and reason code, and the module and CSECT involved.
