BPA - SOA 11g Rountrip problem

Question

Hi,
during evaluating of Fusion Middleware 11g I have the following problem:
In BPA SUuite 11g I created BPMN model, which contains one subprocess. I export the model into BPEL (without errors), but when I try to create a new composite application in Jdev 11g out of that BPEL blueprint I allways get the error message (NullPointerException). The error appers only when the model contains subprocesses. The same thing worked on 10.1.3.4.
Is this a bug or should I set some properties in the BPA Suite?
Thx,
Marcel

Answer 1

Do we need Datasource to be created for each composite?If each composite is connecting to same database and to same schema then it's better to have one data-source. If composites are connecting to different schema's of same DB then you should have separate data-sources for each composite. I personally recommend having separate data-sources for composites which are having very high load.
How many physical connections are required for each data source?No best practices for it. You have to start with some significant number as per your assumption and then increase/decrease the number going forward as per data-source statistics.
What is the best practice followed in these case (only one datasource for all the composites and how many physical connections)? same as second one. No best practices are there in place. Remember that eventually it will also depend on database whether it is able to bear that much load simultaneously.
