Oracle11.2.0.3 ORA-3136 连接超时错误解决

1.问题现象

alert日志文件报如下错误

WARNING: inbound connection timed out (ORA-3136)

sqlnet.log中记录了如下错误:

Tns error struct:

Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.123.103)(PORT=3124))

2.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

如果不重启只是进行reload也可以修改成功

通过如下方式验证是否修改成功

LSNRCTL> show inbound_connect_timeout

修改listener的inbound_connect_timeout参数的方法

方法一:

$ lsnrctl

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
