服务器本地连接自身没有问题,但远程客户端连接时报错,
SQL> show parameter local_listener
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string
SQL> alter system set local_listener='(ADDRESS =(PROTOCOL=TCP)(HOST=192.168.**.***) (PORT=1521)(SID=****))';
System altered.
SQL> alter system register;
System altered.
SQL> exit
客户端再次测试,连接成功!
