Hello,
A webservice is created and deployed in ISD. WSDL has been generated and shared with the user who calls the webservice.
Their requirement is to call the webservice by sending thousands of requests in a minute. so they expect the responses same time. Is there any limit on that or they can call as many requests as possible?
please suggest how to make this work

Chulett,
I will put this in an other way...
Can number of records be passed as single request to the webservice?
as an array or xml?

Yes. But to clarify, there are two variables being discussed here...
1. Requests --- from one or more independently connected SOAP clients. ISD can have many incoming clients. There are perf ...

Right... hadn't gotten down into the weeds yet since that's usually Ernie territory.
1. Meaning you can have many instances of the service running and from what I remember they can increase dy ...

As a side note .....in discussions like this, it is useful to separate the idea of "rows" from the idea of "requests". An array in a single "request" is a "batch of rows".
Leave "requests" to ...

There is always a limit, and you can probably increase it by tuning the ISD settings. It would be nice to know if there were any tuning guidelines documented. The only documentation I have found so far is descriptions of each setting, from the online help.

The most obvious setting is the maximum number of instances of a multi-instance ISD job.

Thank you very much for your inputs.
1) This can be used if the service is being called from different clients.
2)This can be used if single client is sending multiple requests.
As my requirement is single client sending multiple requests, I will check for the array options where number of requests are sent as single array.
Please correct me if I am going to a different route.
can you please guide me through any document that has the array settings or such scenarios?
Thanks again

As noted earlier, a single client can issue any number of requests.....and those requests can send and receive one row.....or many (an array) rows.
How? In the operation secrion you can declare ...
