This message is generated when the "DoubleExponentialOscillatory" method switches its tuning parameters in order to obtain a result that satisfies the requested precision goal. The first parameter is an error estimate tightness factor; the second parameter is used for truncation of the trapezoidal formula (that has an infinite number of terms for "DoubleExponentialOscillatory").
Off[message] switches off the message; On[message] switches it on. For example: Off[NIntegrate::deorela].
