WebSphere DataPower Retries on Long Running Transactions

Technote (FAQ)


Question

We have noticed that on our chained Multi-Protocol Gateways (MPGWs), the first MPGW does retries of the request every 2 minutes if a response is still not received, Is this normal?

Cause

Persistence between chained services (ex: one DataPower Multi-Protocol Gateway acts as the back end for another Multi-Protocol Gateway in the device) will cause repeated retries.

Answer

On Get and Head requests, if persistence is enabled between the two chained MPGWs, then retries will indeed happen. To avoid the retries, "Persistent Connections" radio button (on the PMGW Advanced tab) should be set to off.
