Execution messages

The operator is informed via the console as to why the system dump has been taken.

Depending on the CDUMP2 parameter DIAG the following messages may or may not be displayed (only if the system dump was requested by means of the CDUMP2 macro):

IDA0N50     SYSTEMDUMP CALLED AT LOCATION '(&00)'

insert = { <CDUMP-ad>.(module+nnnnn),EC=...[,ELSN=elsnr#] |
           <CDUMP-ad>.(ABSOLUT),EC=...[,ELSN=elsnr#] }{ [,CODE=code] |
           [,INSERT=insert] }

The following message is always output:


IDA0N51     PROGRAM INTERRUPT AT LOCATION '(insert)'

insert = { <error-ad>.(module+nnnnn),EC=...[,ELSN=elsnr#] |
           <error-ad>.(ABSOLUT),EC=...[,ELSN=elsnr#] }{ [,CODE=code] |
           [,INSERT=insert] }

CDUMP-ad   Hexadecimal CDUMP call address
Error-ad   Hexadecimal error address
module     Module name
EC         Event code
ELSN       Number of Error Logging Sequence Block
CODE       Cause of dump
INSERT     String specifying the cause

The following message is then generally displayed to ask whether the operator wants to generate a system dump and, if so, to which output medium (disk or tape):

IDA0N52  SYSTEMDUMP DESIRED? REPLY (EOT=DISK; VOLUMETYPE=TAPE; N=NO)

The operator may enter the following:

<tsn>.EOT <tsn>.<device-identifier> <tsn>.N

-> -> ->

Output to disk Output to disk Suppress dump

The following entries, among others, can be made for <device-identifier> (see the DEVICE-TYPE operand of the CREATE-FILE command in the “Commands” manual [8]):

TA TAPE T-C4

Any tape device Any tape device tape device of volume type TAPE-C4

As an alternative, responding to the following message (that appears when a user/area dump is output to SYSOUT) leads to the selection of the output medium:

IDA0N45 DUMP DESIRED? REPLY (Y=USER-/AREADUMP TO DISK;
                      Y,<VOLUMETYPE>=USER-/AREADUMP TO TAPE;
                      Y,SYSTEM=SYSTEMDUMP TO DISK;
                      N=NO)

The messages are repeated if an invalid tape device identifier is entered.

If a valid tape device identifier is entered, but the requested device is not available, message IDA0N58 is output on the console and repeated until a correct response is entered.

IDA0N58

TAPE DEVICE TYPE NOT AVAILABLE? REPLY: (EOT=OUTPUT TO DISK; <VOLUMETYPE>=OUTPUT TO TAPE; N=NO)

Messages IDA0N52 and IDA0N58 are followed by messages from device management and from the data management system for controlling dump output (such as MOUNT messages, volume requests etc.).

If an error occurs in the system during dump output, error information (possibly together with an error code) is included in a message (IDA0N63). Output is terminated if necessary (IDA0N61 message).

Correct termination of system dump output is indicated by the message:

IDA0N54  SYSTEMDUMP WRITTEN TO FILE '$SYSDUMP....'

If the dump was output to tape, it must be copied to disk with COPY-FILE or with PERCON utility routine before it is processed by DAMP.
