ERB3XDRS/ERB3XD64 data section layout

When ERB3XDRS returns control to your program after the service has completed successfully, the answer area contains the common header and one or more data sections. Each data section contains a data header followed by the Monitor III data itself. The layout of the data section is as follows:

One or more set-of-samples. The layout of the uncompressed set-of-samples is described in Data gatherer sample structure.

The layout of the data header is

This figure shows the layout of the ERB3XDRS/ERB3XD64 data header and is described in the surrounding text.

where:

DEL

Length of this data section

HDL

Length of this data header

RTN

Data Retrieval return code

RSN

Data Retrieval reason code

DGV

Data gatherer version in the format 'VRM'.

DGS

System name of the system on which the data gatherer is running

MNT

Data gatherer MINTIME option

SAM

Actual number of samples in the returned data

RNG

Actual range length in seconds

BEG

Actual range start time in the format YYYYMMDDHHMMSS.

END

Actual range end time in the format YYYYMMDDHHMMSS.

DRC

Data Reduction exit completion code, if the exit ended abnormally The completion code is in the format TCCCRRRRRRRR, where:

T is 'S' or 'U' for a system or a user completion code, respectively
CCC is the hexadecimal completion code
RRRRRRRR is the hexadecimal reason code associated with the completion code

The following fields will be filled with Monitor III data statistics for certain warning and error conditions.

For return code 8 or 12 and reason code 8 or 9:

DSG: Start time of a time gap in the Monitor III data in store clock format
DEG: End time of a time gap in the Monitor III data in store clock format

For return code 8 or 12 and reason code 15:

DIT: IPL time of the system in store clock format

For return code 12 and reason code 16:

DFA: Start time of the Monitor III data that is available for reporting on this system in store clock format
DLA: End time of the Monitor III data that is available for reporting on this system in store clock format
*: Reserved

Note: The data header length field contains 120 instead of 80 if the additional data statistics are present. If the systems in the sysplex have a different RMF™ service level, both data header formats may appear in the same ERB3XDRS answer area.

Each data section contains the data header described above, followed by the data provided by the data reduction exit routine.
