IBM SC33-1683-02 - Manual (Page 365)

expression
A valid assembler-language expression that can be expressed in 2
bytes.
name2
The name of a 2-byte source of point data
(Rn) A register containing the point data in the low-order 2 bytes
RESPONSE and REASON values for MONITOR:
RESPONSE REASON
OK None
EXCEPTION DATA1_NOT_SPECIFIED
DATA2_NOT_SPECIFIED
POINT_NOT_DEFINED
INVALID_DATA1_VALUE
INVALID_DATA2_VALUE
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. ‘POINT_NOT_DEFINED’ means that the EMP you have specified was not
defined in the MCT.
3. ‘INVALID_DATA1_VALUE’ and ‘INVALID_DATA2_VALUE’ are most likely to have
been caused by provision of bad addresses; this causes a program check.
4. DATA1_NOT_SPECIFIED and DATA2_NOT_SPECIFIED mean that you have
not specified DATA1 or DATA2 respectively when the operation required them.
See the description of DATA2.
5. Any error response terminates processing of the EMP. Operations defined to
execute before the point of failure will have done so; later operations are
canceled.
The INQUIRE_MONITORING_DATA call
The INQUIRE_MONITORING_DATA function returns to the exit program the
performance class monitoring data that has been accumulated for the issuing task.
The DFHMNTDS DSECT that maps the data is of fixed format. Note that:
v All the CICS system-defined fields in the performance records (including fields
that you have specified for exclusion using the EXCLUDE option of the DFHMCT
TYPE=RECORD macro) are listed.
v No user-defined data fields are listed.
