Answer 1

Also you missed cmd.ExecuteNonQuery() in your code. Without executing of command this code will not work regardless of the version of the database.

var cmd = new OracleCommand("select * from new_place", conn);
conn.Open();
cmd.AddRowid = true;
var dep = new OracleDependency(cmd);
dep.OnChange += new OnChangeEventHandler(dep_OnChange);
cmd.ExecuteNonQuery();
