OLEDB Call Event Class

 

Applies To: SQL Server 2016

The OLEDB Call event class occurs when SQL Server calls an OLE DB provider for distributed queries and remote stored procedures.

Include the OLEDB Call event class in traces to monitor only those calls that do not request data or calls that are not made to the QueryInterface method. When the OLEDB Call event class is included in a trace the amount of overhead incurred depends on how frequently OLE DB calls occur against the database during the trace. If calls occur frequently, the trace may significantly impede performance.
