The List Requested Statistics Collections (QDBSTLRS, QdbstListRequestedStatistics) API lists details for not yet completed, or not successfully completed statistics collection requests, requested by a call to the Request statistics collections (OPM, QDBSTRS; ILE QdbstRequestStatistics) API, the Update Statistics Collection (QDBSTUS, QdbstUpdateStatistics) API, or automatically by the system. The generated list replaces any existing list in the user space.
The user space that is to receive the generated list and the library in which it is located. The first 10 characters contain the user space name, and the second 10 characters contain the library name. You can use these special values for the library name:
| *CURLIB | The job's current library or QGPL if the current library is not set. |
| *LIBL | The library list. |
| *USRLIBL | Libraries listed in the user portion of the library list. |
The format of the statistics collections list to be returned. If Format STOP0100 is specified, the fields that were selected by the caller are returned for each statistics collection request in the list. Possible format names are:
| STOP0100 | Statistics collection requests list with keyed return fields. |
Refer to Format of the Generated List and STOP0100 Output Format for more information.
The buffer containing the input parameters according to the format of input data parameter. The buffer content has to start at a 4-byte boundary.

ASP device name used. The actual auxiliary storage pool device name used, after possible resolution of special values.
Note: If the API caller does not have the documented ASP Device Authority for the ASP device, the ASP device name returned will be set to all blanks.
Aging mode. Whether the system is allowed to age or remove the statistics collection. The possible values are:
| *SYS | Refresh or removal of the resulting statistics collections will be performed automatically by the system. |
| *USER | Refresh or removal will only occur when a user requests it. |
Column names. The array of names of the columns within the statistics collection, in the same order as at request time. Each array elements also corresponds to the array element at the same position in the Qualified translation table names field. The array dimension is given by the Number of columns field.
Note: If the API caller does not have the documented ASP Device Authority , File Authority, and File Library Authority for the file containing these specific columns, the column names returned will be set to all blanks.
Continuation handle (input section). The handle used to continue from a previous call to this API that resulted in partially complete information. You can determine if a previous call resulted in partially complete information by checking the Information Status variable in the generic user space header following the API call.
If the API is not attempting to continue from a previous call, this parameter must be set to blanks. Otherwise, a valid continuation value must be supplied. The value may be obtained from the list header section of the user space used in the previous call. When continuing, the first entry in the returned list is the entry that immediately follows the last entry returned in the previous call.
Continuation handle (header section). A continuation point for the API. This value is set based on the contents of the Information Status variable in the generic header for the user space. The following situations can occur:
| Information status-C | The information returned in the user space is valid and complete. No continuation is necessary and the continuation handle is set to blanks. |
| Information status-P | The information returned in the user space is valid but incomplete. The user may call the API again, starting where the last call left off. The continuation handle contains a value which may be supplied as an input parameter in later calls. |
| Information status-I | The information returned in the user space is not valid and incomplete. The content of the continuation handle is unpredictable. |
Data. The data returned for the key identifier.
Displacement to specified fields to return. The displacement to the start of the array of specified fields to return.
Note: This is not the offset specified on input, but the displacement within the input parameter section. See Offset to fields to return specified instead.
Estimated time. The estimated time in seconds to collect the statistics for this request. This will be zero for all request statuses but '0' (pending),'1' (active), and '3' (candidate).
Note: For request status '1' (active), the estimate is for the complete request, not for the remaining work to be done. The also returned progress percentage can be used to calculate the estimated time left before the request is complete.
File library name used. The actual file library name used, after possible resolution of special values.
Note: If the API caller does not have the documented ASP Device Authority and File Library Authority for this specific library, the library name returned will be set to all blanks.
File member name used. The actual file member name used, after possible resolution of special values.
Note: If the API caller does not have the documented ASP Device Authority, File Authority, and File Library Authority for the file containing this specific member, the file member name returned will be set to all blanks.
File name used. The actual file name used.
Note: If the API caller does not have the documented ASP Device Authority, File Authority, and File Library Authority for this specific file, the file name returned will be set to all blanks.
Internal request ID. Uniquely identifies a requested statistics collections. See the Request statistics collections (OPM, QDBSTRS; ILE QdbstRequestStatistics) API.
Key identifier. The field returned. For a list of valid keys see Valid Keys - Request output.
