Can a JCA Adapter Use Both XA and non-XA Data Sources? (Doc ID 1170350.1)

Goal

You have configured an adapter with both XA (global transaction) and non-XA (local transaction) data sources.  But you have some questions.

• Is this allowed?
• Which data source does the adapter use?  Is there a default?
• Suppose you have the following scenario:  

You have a BPEL process which invokes a database adapter with both XA and non-XA data sources defined. The adapter writes to a database table. The next activity in your process calls an Oracle Applications adapter (again with XA and non-XA data sources defined) which calls a stored procedure and throws an error. After the error, on checking the database table which was written to by the database adapter, you find the record is still there.

The transaction should have rolled back and should not have committed the write to the table, correct?

• You have configured a database adapter which you use to call a PLSQL procedure in Oracle E-Business Suite 12.0.4, but you consistently receive the following error on the invoke:  ORA-02089 'Commit Is Not Allowed In A Subordinate Session'.  What's the problem?  Is there a workaround?
