RCVDUMP Program (Super-Group or Super ID
Only)
If on a non-NSAA system, the halted processor to be dumped is running at minimum
the version of Halted State Services included in either the H06.17 RVU on H-series or
the J06.06 RVU on J-series, RCVDUMP by default creates an extracted dump file only,
without first creating a full dump file.
If a full memory dump is to be created, it is created first, followed by implicit postdump
processing of the full dump file to produce a smaller extracted dump file. Although this
additional processing step increases the overall dumping elapsed time and increases
the overall disk space used for the dump files, the benefit is in transferring only the
smaller extracted dump file to GMCSC. The full dump file remains available in case it
needs to be transferred later if information not included in the extracted dump turns out
to be required for the halt analysis.
After performing a TNet dump (full dump), the implicit postdump processing is
executed, by default, when RCVDUMP runs either on an NSAA or non-NSAA system.
On an NSAA system, implicit postdump processing is executed, by default, following a
PARALLEL dump. Implicit postdump processing is not executed following an ONLINE
dump, because the full dump may not provide a complete and consistent set of
information required to select a subset for an extracted dump.
RCVDUMP supports a new option, FULL, that suppresses creation of an extracted
dump file and results in creation of only a full dump file. If only an extracted dump file is
created and the extracted dump information turns out to be insufficient to analyze the
processor halt, it may be necessary to reproduce the halt and use the FULL option of
RCVDUMP to create a full dump file to be used for the analysis.
The files (RCVDUMP, ONLINDMP, POSTDUMP, ZDMPDLL) related to the NonStop
operating system Utilities product, from the H06.14 RVU, can be also be installed to
provide implicit and explicit postdump processing functionality on an HP Integrity
NonStop (NS-series) system running the H06.13 RVU, which does not already have
this functionality by default.
Neither implicit nor explicit postdump processing is supported for a dump of an NS-
series processor that was running a release earlier than the H06.13 RVU, because
insufficient information is available in the full dump to appropriately select a subset for
an extracted dump. For this reason, it is not useful to install the new files on a system
running any release earlier than the H06.13 RVU.
Note. When both full and extracted dump files are created, the full dump file name is changed
to end with an 'F'.
