Box 1: fixed -
The 'Default' policy does 4 exponential retries and from my experience the interval times are often too short in situations.
Box 2: PT60S -
We could set a fixed interval, e.g. 5 retries every 60 seconds (PT60S).
PT60S is 60 seconds.
Scenario: Calls to the Printer API App fail periodically due to printer communication timeouts.
Printer communication timeouts occur after 10 seconds. The label printer must only receive up to 5 attempts within one minute.
Box 3: 5 -
