4. When the program is loaded and waiting for input, signal attention
fro. the virtual console device. The message DEFIlE INPUT DEVICE is sent to your virtual console. Enter the following response fro.
the virtual console: INPUT=type,cuu type is the device type of the device containing state.ents. Valid device types are 2400, 2540, and 3505. the control 3410, 3420, cuu is the device address of the device containing the control statements. Control statements are printed on the message output device. At the
end of job, the END OF JOB message is printed on the message output
device and the program enters the wait state.
VMFDUMP Service' Program and How To Use It CREATING DUKP FILES Conditions can occur during VK/370 processing that cause an abnormal program ending (abend). The system operator can cause this, abend
condition by pressing the SISTEK RESTART key on the system console. If VK/370's control program (CP) recognizes an error condition or program situation where program recovery is not possible or desirable, abend
occurs. The abend procedure creates a historical record of the incident
by dumping register and processor storage contents to a previously
designated device.
The extent of the dump operation as well as the device that captures
this information is specified by operands of the CP SET co •• and. The format of the CP SET DUKP command is: SET raddr r , DU8P {raddr} IQ I AUTO IALLI L .J
(real device address) designates either the syste. printer or a readied nine-track ta.pe, drive (three hexadeci.al digits).
If the printer address is specified, the data is printed
online and system operations as well as virtual machine operations are suspended until the dump operation finishes and
the subsequent system auto.atic restart operation occurs.
This dump is unformatted. The printed dump is the end result
of specifying the system printer in raddr. 10 further
processing or copying of this file is possible. If raddr
refers to a tape drive, the dump data .ust fit on one reel of
tape. Y8/370 does not support .ultiple tape volumes. The
historical data on the tape is in print line format. Iou can Section 4. V8/370 Service Progra.s 193

later in this section for an exaaple of how CBS can do this. IUTO spools abend duaps to a virtual card reader with a class of D
for a specific userid. This userid either is assigned during systea generation to a specific virtual aachine user, or
defaults to the userid of OPERATNS. Thus# only the specified User with a privilege class of C or E can invoke VftFDUMP and
achieve desired results. The duap spool file can be manipulated by the user just like any other spool file, except that it can be interpreted correctly only by the VMFDU!P prograa. The device type and address of this virtual card
reader can be determined issuing a OUERY DUMP co •• and. The systea then responds with the device type and the channel and
unit address of the systea duap device. CP dumps only CP storage. ALL causes all of processor storage (that is, all data that relates to CP as well as all virtual aachines) to be dumped to
the selected deyice. If the ILL option is not specified, then
the systea duaps those areas that pertain to CP, and not those
areas that pertain to user virtual machine operations. Only dumps created by SET DUftP IUTO can be used by the IPCS VMFDUMP service program USING THE YMFDU!P COftBliD the IPCS YftFDUftP co •• and uses the DftftEDft program to read the CP spoo]
reader file that contains the systea du.p and write it on the CMS A-disk. The DftftED! prograa then reads the dump information from the CBS disk, selecting, and formatting various control blocks, which it directs
to the spooled printer (per VftFDUftP operands),. The program also prints
a hexadeci.al duap, then erases or retains the CftS file, on
the options chosen. Only users with privilege class C or E can invoke fftPDUBP. In addition to producing foraatted dump output, VftFDU!P autoaatically generates a problem report file from abend dump information and operator-proapted responses which aids in problem analYSis, is described fully in the Con!!2! 2yid!.
