Multiple XI Instances

[Former Member]

Hi- Does anyone know if there are problems with integrating a single XI instance with multiple backend databases..or is it more advisable to match-up one XI instance with one backend database? Thanks,

If you are talking about multiple application databases, yes. You can connect to as many databases you want. i.e like below

appliaction(databases) <-> XI <-->application(databases)

But if you are talking about XI database(means on which J2EE engine resides) then just one per instance.

Not sure if this is want you want.

Hi- The backend DB holds customer records and is a production system. To be more specific with my question, are there any performance (response time) issues with using one XI instance to directly access 3-4 backend databases that hold customer records..or..will my response times (calls) improve by implementing one XI instance to one DB. thx

An XI system well tuned and sized can access even 100 DB at the same time.

More than DB number it's important to know how many messages par day...

Please follow the sizing guideline at service.sap.com/sizing
