OLEDB QueryInterface Event Class

The

event class occurs when SQL Server issues an OLE DB

call for distributed queries and remote stored procedures. Include this event

class in traces that are monitoring problems associated with distributed queries and remote

stored procedures.

When the

event class is included, the amount of overhead will be high.

If such events occur frequently, the trace may significantly impede performance. To minimize

overhead incurred, limit use of this event class to traces that monitor specific problems for brief

periods of time.
