sqlplus实现远程连接

Oracle 11g:
sqlplus username/password@ip:port/dbname
Oracle 9i:
Sqlplus username/password@ DATABASENAME
把oci.dll所在的目录拷贝到plsql Toolspreferences  OracleHome
D:\app\Administrator\product\11.1.0\db_1\BIN
在OCI Library添加oci.dll
d:\app\Administrator\product\11.1.0\db_1\bin\oci.dll
注：DATABASENAME在tnsnames.ora定义，它里面定义了ip和port
#DATABASENAME =
#  (DESCRIPTION =
#    (ADDRESS_LIST =
#      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
#    )
#    (CONNECT_DATA =
#      (SERVICE_NAME = servicename)
#    )
#  )

Oracle实现远程连接：

Username/Password@IP : Port/DBName
