在listener.ora文件中指定监听的实例名和修改ip地址：
查看实例名：[localhost$] echo $ORACLE_SID
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.193.130)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /home/oracle/app
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /home/oracle/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = orcl)
)
)
将服务器的tnsnames.ora的内容拷贝到客户端的tnsnames.ora记得修改ip
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.193.130)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
