cmdoracle数据库连接
① 怎么在CMD中输入命令，查看数据库oracle是否连接好
1、windows+R，输入CMD点击确定。
② cmd连接远程oracle数据库
您好，提问者：
这样可以是可以，但是如果那个机器没有安装或者配置oracle环境变量就找不到了。
用.bat脚本的时候先检查一下环境变量是否有这个路径存在，如果没有就提示，有就连接。
③ cmd命令连接oracle数据库连接到三个字为什么是乱码
cmd命令窗口字符编码不一致或不兼容。
1、查一下服务器端的字符集。
2、把客户端的字符集设置为一致的。
3、你要用sqlplus的话，先通过设置环境变量来定义客户端的字符集。
④ 如何用cmd命令连接oracle数据库
1，非集群下 Windows环境下数据库
conn scott/[email protected]: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)))

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
