About WebDispatcher's parameter

[Former Member]

Hi Experts!

Now, I investigate about Web Dispatcher's Restrict.

Exactly, I'd like to know as follows.

1. Max Connections

   ->Max requests those are requests at same time.

2. Max Queuing number

  ->In case requests exceed, request must be stayed queue.

3. Max Size of Request

  ->Example, Web Dispatcher can't process the data those are more than 10MB , etc.

4. Timeout

  ->Requests can wait xxx sedonds until they are processed.

5. Remarks & Frequent Troubles about them.

Best Regadrts,

Toshi

Hi Deepak,

Thank you for your quick reply.

But I've already checked it,I couldn't understand what I'd like to know.

It seems that parametes as follows are related to this mater.

But exact terms those I'd like to know aren't described.

Therefore I can't have confidence about it.

1.wdisp/max_servers

     This parameter determines the maximum number of entries

      in the SAP Web dispatcher’s server table

  ->What server table means? Is it request?

2.wdisp/HTTP/max_pooled_con 

3.icm/max_conn

4.cm/max_thread

Hi Deepak,

Thank you so much for your detail reply!

I can understand the general outline.

Finally, I'd like to ask 2 questions.

Q1. Where do "HTTP Request" wait if requets exceed than System Processing Power.

     ->I thinkt that http requests wait in Back-End System, not in Web Dispatcher.

       Web Dispatcher only dispatche HTTP Request.

       The reason why I think so , is there is no parameter that describes queue.

       If they are set by Back-End System(in this case ECC) I'd change ECC Parameter.

Q2.If requests exceed setting value, how request would be?

        Queuing, Abend or nothing happen(not process/not abend/not queue)

       ->I think some error msg would generate Web Dispatcher or  connected System.

Best Regards,

Toshikazu

Hi Toshikazu,

Q1. Where do "HTTP Request" wait if requets exceed than System Processing Power.

Yes. Your understanding is correct. It will be managed by backend system. WebDispatcher will only route the request.

Q2.If requests exceed setting value, how request would be?

In case requests exceed the setting value , it will result in error message in WebDispatcher.
