Two Phase Commit and qpid

[Manuel Teira Paz]

Hello. While estabilizing again the solaris port against the trunk, I'm 
beginning the task to implement a ODBC store for qpid.

I'm a little lost, read some source code, checked out rh-bdb and gave it 
also a look. Is there any documentation about this item? For example, 
I've seen that the class qpid::broker::TransactionalStore has an API 
resembling a Two Phase Commit (TPCTransactionContext and prepare 
method), so , I assume the store must feature two phase commit, or is it 
optional?

Regards.
