客户端配置好服务名后,用PL/SQL Developer连接数据库时,报错:ORA-12504:TNS:监听程序在CONNECT_DATA中未获得SERVICE_NAME。一般这种情况请检查tnsnames.ora文件中TNS是否配置正确,如下所示,SERVICE_NAME 名字弄错了,结果报如上错误:
GSP =
(DESCRIPTION =
(ADDRESS =(PROTOCOL = TCP)(HOST = 172.20.36.79)(PORT = 1521))
(CONNECT_DATA=
(SERVER = DEDICATED)
(SERVER_NAME = gsp)
)
)
修改为
GSP =
(DESCRIPTION =
(ADDRESS =(PROTOCOL = TCP)(HOST = 172.20.36.79)(PORT = 1521))
(CONNECT_DATA=
(SERVER = DEDICATED)
(SERVICE_NAME = gsp)
)
)
