Does XI work as a cache of the backend system?

[Former Member]

Hello experts,

We have a synchronous scenario like R/3->XI->webservice.

R/3 is search data from webservice via XI.Thinking of performance reason,we are planning to make XI as a data cache to work .So the R/3 not need to access backend system(webservice) any more for the same request.it only need to access Xi to get the data.As consideration,please give me a advice how i can realize it?

Hi,

Instead of having a call to the webservice (which takes lot of time )to access back-end you can also directly access the backend using java mapping. In your java mapping you can access the database.

Hi

Thank you very much for your solution.yes,using java mapping

to access back end database directly seems a good idea.but i still want to know the XI whether can be as a cache to work.it is also the question from our customer.

Hi,

You can go ahead with value mapping too so that you need not to retreive the data everytime from the backend.

Check these once.

I still do not understand what you said.Why it need not to retrieve the data from backend system every time if i create the value mapping ?Does the value mapping has the standard function to cache the message?

Hi,

The performance reason said by you ,is it in terms of time XI takes to call the webservice?

Hi Progirl,

Yes,it is for decreasing the time to access webservice.
