RECEIVEDUMP Command (Super-Group Only)
param
is either one of these parameters:
FULL
specifies that the entire physical memory is to be dumped. FULL is the default
for a processor if the size of physical memory is less than or equal to sixteen
megabytes. This option is ignored if the processor is not a VLX.
PARTIAL
specifies that only those pages of physical memory that are mapped in the
page table cache are to be dumped. PARTIAL is the default for a processor
with more than sixteen megabytes of physical memory. This option is ignored if
the processor is not a VLX.
Considerations
•
If the file dump-file does not exist when you enter the RECEIVEDUMP
command, a new file named dump-file is created.
D-series: If dump-file exists, it must be empty; that is, its end-of-file (EOF)
pointer must be set to zero. If dump-file is not empty, it is not overwritten:
RECEIVEDUMP returns an error message. Also, if the empty dump-file exists,
but its primary and secondary extent sizes are too small to contain the entire
dump, the file is purged and a new dump-file with extent sizes of sufficient size
is created.
G-Series: If the file already exists RCVDUMP prompts the user to specify whether
it can overwrite the file. If the answer is ' no', RCVDUMP aborts. Otherwise it
overwrites the existing file and continues.
•
Any dump file created with RVU G06.16 or later has a file code of 145. Any dump
file created with an earlier RVU has a file code of 144.
Example
For G-series RVUs, if you have a super-group user ID, you can initiate a dump from
processor 4 of your system over the Y fabric and send the dump to file
$SYSTEM.DUMP.DUMP2 by entering:
74> RECEIVEDUMP /OUT $SYSTEM.DUMP.DUMP2/ 4,1
CPU 04 HAS BEEN DUMPED TO $SYSTEM.DUMP.DUMP2.
Note. The PRIME and NOPRIME parameters do not have any effect on how the
RCVDUMP command operates. They are therefore no longer described in the RCVDUMP
command description.
