解决Oracle10gR2 ORA-3136 错误

今早发现数据库alert日志报如下错误

WARNING: inbound connection timed out (ORA-3136)

 

sqlnet.log报如下错误

 

Fatal NI connect error 12170.

查Metalink,给出了如下处理办法:

 

1.set INBOUND_CONNECT_TIMEOUT_=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
