一篇介紹 connection pooling 的文章
http://msdn.microsoft.com/library/defau ... oling2.asp

其中提到有關是否要 pooling 的 connection string 的設置,
Table 4. Setting OLE DB Services by Using ADO Connection String Attributes
Services enabled value in connection string
All services (the default) "OLE DB Services = -1;"
All services except pooling "OLE DB Services = -2;"
All services except pooling and auto-enlistment "OLE DB Services = -4;"
All services except client cursor "OLE DB Services = -5;"
All services except client cursor and pooling "OLE DB Services = -6;"
No services "OLE DB Services = 0;"

相當且參考價值.
