Maximum HTTP posts to "Plain HTTP" adapter

[Former Member]

Hello,

I am working on some load testing on a development box that we have for a simple synchronous HTTP<>XI<>RFC interface. I have tested up to around 45 simultaneous users and the XI box starts to reply with 500 Internal Server Errors to the HTTP posts. Up until that point it processes the messages fine and returns the correct response and 200 OK codes.

Could someone direct me to the configuration on the XI box for the maximum number of HTTP requests to process or an explanation of why the server starts to drop POSTs? Thanks for your help!

Regards,

Hi,

have a look at those two parameters from the XI profile:

icm/HTTP/max_request_size_KB

Maximum size of HTTP request accepted by ICM

and

connection timeout:

icm/server_port_<xx>

maybe these will help

Thanks for the suggestions Michal!

I am also thinking that it might be an OS level problem as well. Being an HP-UX box, the default kernel parameter for max threads per process is 64, and thus will start to drop connections when the amount reaches close to that threshold. Has anyone else seen this problem? I will probably end up talking to the admin of that server about this.

Thanks for the help.
