根据自己的安装路径修改2个地方listener.ora和tnsnames.ora

我的路径在：E:\app\Administrator\product\12.2.0\dbhome_1\network\admin

listener.ora文件

# listener.ora Network Configuration File: E:\app\Administrator\product\12.2.0\dbhome_1\NETWORK\ADMIN\listener.ora
# Generated by Oracle configuration tools.SID_LIST_LISTENER =(SID_LIST =(SID_DESC =(SID_NAME = CLRExtProc)(ORACLE_HOME = E:\app\Administrator\product\12.2.0\dbhome_1)(PROGRAM = extproc)(ENVS = "EXTPROC_DLLS=ONLY:E:\app\Administrator\product\12.2.0\dbhome_1\bin\oraclr12.dll")))LISTENER =(DESCRIPTION_LIST =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.32)(PORT = 1521)))(DESCRIPTION =(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))))ADR_BASE_LISTENER = E:\app\Administrator\product\12.2.0\dbhome_1\log

 tnsnames.ora文件
