End user is paging through queried data (SELECTs) when the database failure occurs.

Oracle reconnects and reconstructs the database session on a surviving node, re-executes the query, repositions the SQL cursor, and returns the next set of rows.

End user is issuing a new query (SELECTs) or switching screens just after the database failure.

Oracle reconnects and reconstructs the database session on a surviving node.
