使用plsql登录数据库,提示报错ORA-12514
1.监听未启动
2.修改tnsnames.ora,一般在 D:\oracle\product\10.2.0\client_1\NETWORK\ADMIN 目录下。将HOST改成127.0.0.1,将服务名 SERVICE_NAME 改为实际数据库SID。
HTOA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = ORCL) ) )
修改完成后重启监听
