代码如下：
<%
on error resume next
'连接数据库
Set OraSession = CreateObject("OracleInProcServer.XOraSession")
set oradatabase=orasession.dbopendatabase("数据库名","用户名/密码",0)
'出错处理
if err.number >0 then
Response.Write "<h4>asp 错误控制</h4>"
Response.Write "asp 错误来源:"&err.Source &"<br>"
Response.Write "asp 错误代码:"&err.number &"<br>"
Response.Write "asp 错误说明:"&err.Description &"<br>"
err.Clear
Response.Write "<h4>ORACLE OLE 错误控制</h4>"
Response.Write "ORACLE 错误代码"&OraSession.lastServerErr&"<br>"
Response.Write "ORACLE 错误说明"&OraSession.lastServerErrtext&"<br>"
closeDatabase
displayerror
Response.end
end if
'关闭数据库
sub closeDatabase()
oradatabase.close
'set oradatabase=nothing
orasession.close
set orasession=nothing
end sub
function displayerror()
if err.number <>0 then
Response.Write "<br><br><br><p align=center fontsize=20>数据库连接失败，请与系统管理员联系！</p>"
Response.End
end if
end function

解决办法：
1、IIS要访问ORACLE数据库时，在OLEDB中赋于一个权限（是ORACLE的BUG）
在ORACLE_HOME目录下ORA92目录的属性里的安全性上添加/编辑“Authenticated Users”用户，在其“读取及运行”权限上先点不选，再点选择，然后“应用”。
2、在ORACLE_HOME目录下ORA92\network\ADMIN目录里有一个“sqlnet.ora”文件，
内容如下：
# SQLNET.ORA Network Configuration File: E:\oracle\ora92\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
NAMES.DEFAULT_DOMAIN = jgc-new.local
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
将其改为：
# SQLNET.ORA Network Configuration File: E:\oracle\ora92\network\admin\sqlnet.ora
# Generated by Oracle configuration tools.
NAMES.DEFAULT_DOMAIN = jgc-new.local
# SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
