DW1C1->oracle database->target setup -> Monitoring configuration-> Instances-> selected DW1C_DW1C1 -> Test Connection and It was successful."

In a RAC configuration there are 2 or more "Test Connection" buttons. The one above is to test the connection of the Whole RAC, the others below are to test connection for each instance individually. Normally the "Test Connection" button for the instances is disabled. To test the instance select the broken instance individually and then test that connection.

Symptoms

After creating an incident rule to monitor up/down for our database instances on a RAC cluster.
The metric evaluation was failing after 12000 ms for a couple of database instances and all instances with this issue belong to one node(RACDEV2).
