HP Neoview Release 2.4 Software - Manual (Page 29)

NOTE: In both ODBC_QUERY_STATS_V1 and ODBC_QUERY_STATS_V2, the QUERY_ID
field contains the unique ID of the query unless an error occurs before the query is launched. In
this case, no query ID is assigned, and the corresponding field is populated with the value
. The rest of the information pertaining to the query, including the error code, is stored
in the appropriate columns.
VIEW NEO.HP_METRICS.QUERY_RUNTIME_STATS_V1
This view provides information collected while a query is running. The Repository obtains this
information through a statistics gathering process within the Neoview Management Dashboard.
Because statistics are updated as the query executes, you can use this view to monitor running
queries. The Repository data for the SERVICE_INDEX and QUERY_INDEX columns in the
QUERY_RUNTIME_STATS_V1 table are not available from the data provider. As a result, the
column values will be zero.
With regard to when query statistics will be present, a single row is written per query execution.
Thus, if the same query is executed 3 times, 3 rows will be present. If a query runs for a long time
(that is, longer than the configured data collection interval), the statistics for that query will be
updated at each data collection interval.
When compared with the other available views that provide information for queries, this one
contains many additional fields. Fields available only in this view are marked with asterisks (*)
in the list below.
Note that only queries managed by Neoview Workload Management Services are reflected in
this view. For information about the features and limitations of WMS, see the Neoview Workload
Management Services Guide.
Also note that query completion statistics are not guaranteed to be present in this view.
The interval for collecting data while a query runs is set in the Dashboard configuration. Contact
your HP Support representative for assistance in changing the configuration.
Character columns use ISO88591 or UCS2 encoding, as appropriate to the Neoview platform
configuration. In the following table:
• If a data type is given as CHAR or NCHAR, then CHAR applies if the character set is
ISO88591, and NCHAR applies if the character set is UCS2.
• If a data type is given as VARCHAR or NCHAR VARYING, the VARCHAR applies if the
character set is ISO88591, and NCHAR VARYING applies if the character set is UCS2.
The primary key for QUERY_RUNTIME_STATS_V1 field definitions is SEGMENT_ID, NODE_ID,
PIN, and SUBMIT_TS.
