Question

You are using xRoute on the PTV xServer 2 SaaS/Cloud platform and want to know how long a request can run before the server terminates it. You tried setting queueingTimeout and computationTimeout in the request but the parameters have no effect.

Answer

On the PTV xServer 2 SaaS/Cloud platform, request-specific timeout parameters are intentionally disabled for security reasons. The parameters timeouts.queueingTimeout and timeouts.computationTimeout in the request body are not enforced and will not produce a timeout error even if set to very low values.

The server-side timeout values are fixed and based on the default xServer 2 configuration:

• Request queue timeout: 60 seconds (core.requestQueueTimeout)
• Computation timeout: 60 seconds (core.moduleTimeout)

The maximum total execution time is therefore approximately 2 minutes (queueing time plus computation time combined).

These values cannot be modified by the client on the SaaS platform.

Additions hints

• On xServer 2 On-Premise installations, request timeouts are enabled by default (core.enableRequestTimeouts = true) and the timeouts parameters in the request body are respected.
• On the SaaS/Cloud platform, core.enableRequestTimeouts is set to false, which is why client-supplied timeout values have no effect.
• If a request does not return within approximately 2 minutes on the SaaS platform, it is likely due to a very large or complex calculation rather than a misconfiguration.
