Setting Provider Service Defaults

Individual OLE DB services can be enabled or disabled by default for all consumers that access a single provider. This is done by adding an OLEDB_SERVICES registry entry under the provider's CLSID, with a DWORD value specifying the services to enable or disable as shown in the following table.

Default services enabled	DWORD value
All services (default)	0xffffffff
All except pooling	0xfffffffe
All except pooling and automatic transaction enlistment	0xfffffffc
All except Client Cursor Engine	0xfffffffb
All except pooling, automatic transaction enlistment, and Client Cursor Engine	0xfffffff8
Pooling and automatic transaction enlistment, session level aggregation only	0x00000003
No services	0x00000000
No aggregation, all services disabled	(No registry entry)
