Important
There is a restriction in using the XPI early during initialization. Do not start
exit programs that use the XPI functions TRANSACTION_DUMP,
WRITE_JOURNAL_DATA, MONITOR, and INQUIRE_MONITOR_DATA until
the second phase of the PLTPI. For further information about the PLTPI, refer
to “Chapter 4. Writing initialization and shutdown programs” on page 393.
DATA_BUFFER(buffer-descriptor)
specifies the address and the length of a buffer to contain the returned
monitoring data; see page 299 for a full definition of a buffer-descriptor. The
DSECT DFHMNTDS maps the monitoring data.
RESPONSE and REASON values for
INQUIRE_MONITORING_DATA:
RESPONSE REASON
OK None
EXCEPTION LENGTH_ERROR
MONITOR_DATA_UNAVAILABLE
DISASTER None
INVALID None
KERNERROR None
PURGED None
Notes:
1. For more detail, refer to the explanation of RESPONSE and REASON in
“General form of an XPI call” on page 286.
2. ‘LENGTH_ERROR’ means that the length specified in the buffer-descriptor was
too short for the monitoring data returned from the XPI call.

calls:
INQUIRE_PROGRAM
INQUIRE_CURRENT_PROGRAM
