经过摸索和实践，我把自己的解决方法，写在下面：
说明：
我的Oracle客户端的版本是 oracle 9i， 安装client端的时候，不能用默认安装，一定要自定义， 然后选择所有 OLEDB 相关的内容，都装上，否则到下面的 Provider 的时候，会找不到。
复制代码 代码如下:
<%@Language="VBSCRIPT" CodePage="936" LCID="2052"%>
<%Option Explicit%>
<!-- #include file="../adovbs.inc" -->
<%
Dim cnOra
Function Connect2OracleServer
Dim conStr
conStr = "Provider=MSDAORA.Oracle;Data Source=xx;User Id=?;Password=?"
Set cnOra = Server.CreateObject("ADODB.Connection")
cnOra.CursorLocation = adUseClient '=3
On Error Resume Next
cnOra.Open conStr
Connect2OracleServer = (Err.Number = 0)
End Function
Sub DisconnectFromOracleServer
If Not cnOra is Nothing Then
If cnOra.State = 1 Then
cnOra.Close
End If
Set cnOra = Nothing
End If
End Sub
Sub Echo(str)
Response.Write(str)
End Sub
Sub OutputResult
Dim cmdOra
Dim rs
Set cmdOra = Server.CreateObject("ADODB.Command")
With cmdOra
.CommandType = adCmdText '=1
.CommandText = "{call PKG_TEST.GetItem(?,?)}"
.Parameters.Append cmdOra.CreateParameter("p1", adNumeric, adParamInput, 10, 1)
.Parameters.Append cmdOra.CreateParameter("p2", adVarChar, adParamInput, 10, "xx")
.ActiveConnection = cnOra
Set rs = cmdOra.Execute
If Not rs.Eof Then
While Not rs.Eof
Echo rs(0)
Echo "--"
Echo rs(1)
Echo "<br>"
rs.MoveNext
Wend
rs.Close
End If
Set rs = Nothing
Set cmdOra = Nothing
End With
DisconnectFromOracleServer
End Sub
If Connect2OracleServer Then
OutputResult
Else
Response.Write(Err.Description)
End If
%>
