Webservice timeout

[LeonardoAraujo]

Guys,

I created a ABAP webservice to be consumed by a .NET application.

Since some of the calls process long updates in SAP and they are getting timeouts.

1 - what is the procedure to troubleshoot which timeout parameter should I play with?

2 - What are the recommended values for them?

I know the icm/server_port_ < n > TIMEOUT and PROCTIMEOUT parameters and also icm/keep_alive_timeout , but I am not sure which one is the one I should be adjusting.

Here are my current values:

Any help is appreciated.

Thanks,

Leonardo De Araujo

Hi Leonardo,

we had a similar issue with our BSP-application on long running selections.

We increased the parameter icm/keep_alive_timeout (sec.) from 60 to 180 seconds to avoid a timeout. This works fine, but: this change has some disadvantages

- your system load increases

- the long runtim may cause security issues

I hope that helps.
