Hi all,
We have a requirement to read some xml files from an external system when they are ready. It would be ideal to set up an API in Appian to receive a call when a file is ready but this is not an option for limitations in the external system. We have to invoke from Appian a web service every x minutes to retrieve the files.
The question is, how often to do it? The requirement says we should call the external system "at least twice per minute" which I think is too frequent. As the standard timeout setting of Web Service calls is 120 ms I think we could have difficulties if we invoked the service more frequently than that.
I really dont like having to generate process instances every 5 minutes but I would like to know what is the recommendation here? The customer wants to see the files quickly. How often would you generate a process for this?
Thanks a lot

The minimum time can you start a process is 5 minutes, i suggest to create an utility process will to be deleted after completition.In this model, you can call, with MNI (or similar) a process every X time, X determined with a timer and a specific expression.
obviously the process have to be completed before 5 minutes.
I hope to gave you an idea.
