通常按网上各贴所言，配置对listener.ora和tnsnames.ora即可。然而我耐心的比较了几个小时- -，也没发现有什么不对的地方。
重点是这里
注意到了吗。监听的名字不知道什么时候变成了ORACLEOraDb11g_home1TNSListenerLISTENER1！（可能是使用oracle自带工具重新配置监听导致的）这意味着，此时listener.ora的配置需要相应调整如下：
# listener.ora Network Configuration File: D:\ORACLE\product\11.2.0\dbhome_1\network\admin\listener.ora# Generated by Oracle configuration tools.LISTENER1 =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = che-PC)(PORT = 1521))))SID_LIST_LISTENER1 =(SID_LIST =(SID_DESC =(GLOBAL_DBNAME = ORCL)(ORACLE_HOME =D:\Oracle\product\11.2.0\dbhome_1)(SID_NAME = ORCL))(SID_DESC =(SID_NAME = CLRExtProc)(ORACLE_HOME = D:\ORACLE\product\11.2.0\dbhome_1)(PROGRAM = extproc)(ENVS = "EXTPROC_DLLS=ONLY:D:\ORACLE\product\11.2.0\dbhome_1\bin\oraclr11.dll")))
LISTENER1和SID_LIST_LISTENER1都应该与服务名对应。
