原来配置：listener.ora文件如下：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = DESKTOP-L9P3QTT)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
修改如下
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=DESKTOP-L9P3QTT)(PORT=1521)(RATE_LIMIT=yes))
(ADDRESS=(PROTOCOL=tcp)(HOST=DESKTOP-L9P3QTT)(PORT=1522)(RATE_LIMIT=yes))
(ADDRESS=(PROTOCOL=tcp)(HOST=DESKTOP-L9P3QTT)(PORT=1523)))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
重启监听服务
启动监听
查看端口
测试连接
输入sqlplus system/oracle@localhost:1521/orcl
sqlplus system/oracle@localhost:1522/orcl
sqlplus system/oracle@localhost:1523/orcl
测试连接
