Prerequisites for the Amazon EC2 adapter

Amazon EC2 adapter requests are signed and valid for a limited period to avoid replay attacks.

The validity of the adapter request is controlled by the <time-to-live> configuration element, which is set to 60 seconds by default. In other words, a request is valid for only one minute from the current time on the BMC Atrium Orchestrator peer.

Therefore, either if the clock settings on the peer are incorrect or not synchronized with the Network Time Protocol (NTP) or if the request takes more than the default time (normally over slow internet connections), the "javax.xml.ws.soap.SOAPFaultException: Request has expired" error is displayed.

You can increase the value of the <time-to-live> element in the adapter configuration as follows:
<time-to-live>180</time-to-live>
