ORACLE920与ASP的连接问题的解决办法







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)
