CMD命令下访问Oracle数据库

1.非集群下 Windows环境下数据库 

127.0.0.1 只是个IP代表  实际要输入你要访问的数据库服务器IP地址的

如果数据库服务器不在本机上，需要加上数据库服务器的地址：用户名/密码@IP地址/数据库名称。

①运行->cmd

sqlplus/nolog 然后

第一种方式 ：conn scott/[email protected]:1521/orcl

第二种方式：conn scott/123456@(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))

Linux环境下数据库
conn scott/123@(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521)))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))

集群下连接

conn scott/123@(DESCRIPTION=(ADDRESS_LIST=(LOAD_BALANCE = yes)(FAILOVER = on)(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.1)(PORT=1521))(ADDRESS=(PROTOCOL=TCP)(HOST=127.0.0.2)(PORT=1521)))(CONNECT_DATA=(SERVER=default)(SERVICE_NAME=orcl)))
