ORA-03136

inbound connection timed out

Cause

The inbound connection was timed out by the server because user authentication did not complete within the time specified by SQLNET.INBOUND_CONNECT_TIMEOUT or its default value.


Action

  1. Check the SQL*NET and RDBMS logs for traces of suspicious connections.
  2. Configure SQL*NET with a larger value for the SQLNET.INBOUND_CONNECT_TIMEOUT parameter, if necessary.
