Timeout for Asynchronous BPELs
For asynchronous BPELs, the timeout period for receiving the response can be
defined in terms of seconds, minutes, hours, days, months, or years. The default is
indefinite timeout. The timeout response can call other services or return a message
to the initial caller.
In BPEL, the asynchronous timeout is implemented with one Invoke and one Pick
at the client end and one Receive and one Invoke at the provider end. In the Pick
activity, the timeout period can be specified.
Since some of the asynchronous services take a long time to return a response, you
can use the Pick activity to perform other duties instead of waiting for a response.
The expiration time can be set by using the Wait activity.
