1, first you will use Sqlplus to connect to the remote database
Sqlplus username/password @ remote database IP: Port/Instance Name
2. Use command after successful connection

sql>@E:\areadata.sql;sql>@/opt/oracle/area.sql;

Sometimes the Chinese will appear garbled problem, or error. For example:

ERROR:ORA-01756: quoted string not properly terminated

sql>select userenv(‘language‘) from dual;---AMERICAN_AMERICA.ZHS16GBK【此处的字符集是这个】

2. Troubleshoot the client character set
Under the Windows platform, it is the Nls_lang of the corresponding oraclehome in the registry. You can also set it yourself in a DOS window, such as:
set nls_lang=AMERICAN_AMERICA.ZHS16GBK

Under Linux, modify the Bash_profile file

$ vi .bash_profileNLS_LANG=‘AMERICAN_AMERICA.ZHS16GBK‘; export NLS_LANG

This may also be related to SQL files, you can try to set the client character set, try two more should be.

In addition, some files may appear some characters such as spaces, into the sqlplus inside will become?, such as the following waiting for input, often affect the import time:
Sql>enter value for nbsp;

So you need to set the turn off substitution variable function when executing sql>@e:\areadata.sql
Sql>set difine off;
