    How can an existing working connection start failing with "Network Adapter not able to establish connection?

    worksfire1

      I can't get my previous database connection called system_connection_orcl to connect.  I just don't understand why all the sudden a connection that worked is having this problem randomly.  Some times it connects fine, other times, it doesn't.   I have internet on this machine up and running.


      Connection name: system_connection_orcl

      Username: system

      Password: [ my password ]

      Save Password: Yes

      Connection Type: Basic

      Role: default

      Hostname: localhost

      Port: 1521

      SID: orcl

       


      Then I click "TEST" and it returns the following error:

      Status: Failure - Test failed:IO Error: The network adapter could not establish the connection.
