安装Oracle完整客户端后没有访问接口OraOLEDB.Oracle解决办法


    安装Oracle完整客户端后,没有访问接口OraOLEDB.Oracle,是因为Oracle客户端安装时没有往注册表里面写入驱动信息。
    注意3里面的路径要换成你客户端安装的路径
    
[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D- 
00C04FA30080}\InprocServer32]中的值:
@="D:\\app\\client\\product\\11.2.0\\client_1\\BIN\\OraOLEDB11.DLL"

    此值是根据你安装Oracle客户端的路径的值,必须保持一致。
    首先要修改一下注册表内容(把1/2/3/4 考下来变成reg格式文件依次执行):
    1、Windows Registry Editor Version 5.00
    
REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\OraOLEDB.Oracle]
@="Oracle Provider for OLE DB"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\OraOLEDB.Oracle\CLSID]
@="{3F63C36E-51A3-11D2-BB7D-00C04FA30080}"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\OraOLEDB.Oracle\CurVer]
@="OraOLEDB.Oracle.1"

    2、Windows Registry Editor Version 5.00
    
REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\OraOLEDB.Oracle.1]
@="Oracle Provider for OLE DB"

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\OraOLEDB.Oracle.1\CLSID]
@="{3F63C36E-51A3-11D2-BB7D-00C04FA30080}"

    3、Windows Registry Editor Version 5.00
    
REGEDIT4

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}]
@="OraOLEDB.Oracle"
"OLEDB_SERVICES"=dword:ffffffff

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\ExtendedErrors]
@="Extended Error Lookup Service"

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\ExtendedErrors\{3FC8E6E4-53FF-11D2-BB7D-00C04FA30080}]
@="Oracle OLE DB Error Lookup"

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\InprocServer32]
@="D:\\app\\client\\product\\11.2.0\\client_1\\BIN\\OraOLEDB11.DLL"
"ThreadingModel"="Both"

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\OLE DB Provider]
@="Oracle Provider for OLE DB"

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\ProgID]

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\TypeLib]
@="{0BB9AFD1-51A1-11D2-BB7D-00C04FA30080}"

[HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\VersionIndependentProgID]
@="OraOLEDB.Oracle"

    4、Windows Registry Editor Version 5.00
    
REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL10.MSSQLSERVER\Providers\OraOLEDB.Oracle]
"AllowInProcess"=dword:00000001
