原来配置好的数据库监听用plsql登陆报错ORA-12514 TNS 监听程序当前无法识别连接描述符中请求服务
网上说的改listener.ora 添加如下配置
SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (SID_NAME = ORCL) (ORACLE_HOME = D:\oracle_base\oracle11g\product\11.2.0\dbhome_1) (PROGRAM = ORCL) ) (SID_DESC = (GLOBAL_DBNAME = MONT) (ORACLE_HOME = D:\oracle_base\oracle11g\product\11.2.0\dbhome_1) (SID_NAME = MONT) ) )
改了以后并不起作用
错误原因在tnsnames.ora里面
修改前
MONT = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.169.6.64)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = MONT) ) )
SERVICE_NAME = MONT要和实际数据库SID一样
外面的可以随便，区分不同的数据库
修改后
MONT = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.169.6.64)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORCL) ) )
