Purpose
Determines whether DBQL logs a pseudo step labeled “RESP” in the DBQLStepTbl table when the last response to a DBQL logged request is completed. This can be used together with the FirstRespTime log entry in the DBQLogTbl to calculate the approximate response time experienced by the client.
Field Group
General
Valid Settings

Usage Notes
This field is effective only when DBQL logging is enabled. The RESP pseudo step entry is logged for every query that is logged to the DBQL default table, regardless of whether STEPINFO or other DBQL options are requested.
When enabled, the RESP pseudo step is logged even if the request aborts or experiences an error. It indicates when the logged request ends for any reason.
