WARNING inbound connection timed out (ORA-3136)问题的处理

WARNING inbound connection timed out (ORA-3136)问题的处理
这是和网络连接相关的一个错误,Metalink上给出了如下的解决方案:

1.set INBOUND_CONNECT_TIMEOUT_<listenername>=0 in listener.ora
2.set SQLNET.INBOUND_CONNECT_TIMEOUT = 0 in sqlnet.ora of server.
3.stop and start both listener and database.
4.Now try to connect to DB and observe the behaviour

详细的解决：

修改listener的inbound_connect_timeout参数的方法

LSNRCTL> show inbound_connect_timeout
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
LISTENER parameter "inbound_connect_timeout" set to 60
The command completed successfully

LSNRCTL> set inbound_connect_timeout 0
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
LISTENER parameter "inbound_connect_timeout" set to 0
The command completed successfully

LSNRCTL> show inbound_connect_timeout
Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521))
LISTENER parameter "inbound_connect_timeout" set to 0
The command completed successfully

LSNRCTL> set save_config_on_stop on  #表示修改参数永久生效，否则只是临时生效，下次重启监听又还原为原来的值了
LSNRCTL> exit

方法二：
修改listener.ora文件，加入: INBOUND_CONNECT_TIMEOUT_LISTENER_NAME=0
