怎么设置AE连接ORACLE的参数

如何设置AE连接ORACLE的参数
那位高手能帮忙解决一下，通过ae接口如何连接oracle数据库啊？
HRESULT hr;
IPropertySetPtr pSet;
hr = pSet.CreateInstance(__uuidof(PropertySet));
hr = pSet->SetProperty("SERVER", _bstr_t("192.168.10.177"));
hr = pSet->SetProperty("DATABASE", _bstr_t(database));
hr = pSet->SetProperty("USER", _bstr_t(username));
hr = pSet->SetProperty("PASSWORD", _bstr_t(password));
hr = pSet->SetProperty("INSTANCE", _bstr_t("oracle11g"));
pSet->SetProperty("VERSION", _bstr_t("SDE.DEFAULT"));
pSet->SetProperty("DISABLE", _bstr_t("0"));
esriwms::IWorkspaceFactoryPtr pWrkFct;
hr = pWrkFct.CreateInstance(__uuidof(esriwms::SdeWorkspaceFactory));

高手们请给看看，这些参数应该如何修改啊？

------解决方案--------------------
hr = pSet->SetProperty("DATABASE", _bstr_t(database));

如果是Oracle ，这个不用填，或者填Empty
