Setting communication stub data
The DataRequester
interface contains API requester data that is sent to
the IBM® z/OS® Connect server from the communication
stub. Most data is automatically set but some items require specific action for the values to be
set.
Setting the CICS_UOWID and CICS_NETUOWID values
Values are set for the CICS_UOWID
and CICS_NETUOWID
data items
in the com.ibm.zosconnect.spi.DataRequester interface for requests from CICS® applications if the BAQCTRUE TRUE is configured in the CICS region. For more information, see Configuring enhanced monitoring for CICS tasks.
Setting the IMS_EXIT_DATA value
Values can be set for the IMS_EXIT_DATA
and IMS_EXIT_DATA_BYTES
data items in the com.ibm.zosconnect.spi.DataRequester interface for requests from IMS applications by a monitoring product or
application. The IMS_EXIT_DATA
provides a string representation of the exit data
whereas IMS_EXIT_DATA_BYTES
is the raw, unconverted, exit data.
To provide this data the IMS communication stub makes INQY
calls to request information about the execution environment. These calls can be intercepted by the
IMS Monitor user exit (IMSMON). The I/O area
parameter on the INQY call specifies the data output area for the call and when the communication
stub allocates data for this I/O area, it allocates extra storage before the I/O area as shown in
Table 1. On the INQY call, before the API
request is sent to the IBM z/OS Connect server, the
eye catcher is set to ZOSCONNECT-V3->>
. A monitoring product can set a
correlator or other value in this data area before the I/O area.
Bytes | Field | Description |
---|---|---|
0-15 | Eyecatcher | Set with the EBCDIC character string ZOSCONNECT-V3->> before
an API request and ZOSCONNECT-V3-<< after an API request. |
16-79 | Exit data | Field that can be set by a monitoring product. The value is transmitted to the
IBM z/OS Connect and is set as the value of
IMS_EXIT_DATA . |
80+ | I/O area | The I/O area that is passed on the call to INQY. |
After the API request, the communication stub makes a second call to INQY with the eye catcher
ZOSCONNECT-V3-<<
set.
