怎么用oracle命令连接远程数据库

配置好相关的文件就可以，一般是tnsname.ora文件。

一般oracle10g的文件所在目录为：C:\oracle\product\10.2.0\db_1\network\ADMIN

其他版本的可在oracle目录下搜索tnsname.ora文件名进行修改。

ora =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = xxx.xxx.xxx.xxx)(PORT = 1521))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

)

)

其中ora为本地实例名，xxx.xxx.xxx.xxx为远程IP地址，1521为端口号，orcl为远程数据库实例名，按照对方提供的内容进行修改即可。

1，非集群下 Windows环境下数据库

conn scott/123@127.0.0.1:1521/orcl

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)))

2，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)))

扩展资料

在命令行中登录oracle数据库：

sqlplus username/password  如：普通用户登录  sqlplus scott/tiger

sqlplus username/password as sysdba 如：sqlplus sys/admin as sysdba

sqlplus username/password@net_service_name 如: sqlplus scott/tiger@orcl

sqlplus username/password@//host:port/sid
