解决办法:
We often recommend increasing the values forINBOUND_CONNECT_TIMEOUTat
both listener and server side sqlnet.ora file as a preventive measure.
If the problem isdue to
connection timeouts, an increase in the following parameters should eliminate or reduce the occurrence of the ORA-609s.
Sqlnet.ora: SQLNET.INBOUND_CONNECT_TIMEOUT=180
http://blog.csdn.net/eviswang/article/details/49923005
Listener.ora: INBOUND_CONNECT_TIMEOUT_listener_name=120
http://blog.csdn.net/eviswang/article/details/49923229
Also, please set the following parameter:
sqlnet.ora file (on the server): DIAG_ADR_ENABLED = OFF
Reload the listener:
$lsnrctl reload
