1. prepare JMS name1,Xid1
2. prepare DB name2,Xid2
3. prepare TX log (write name1,Xid1 and name2,Xid2)
4. commit JMS name1,Xid1
5. crash
6. recover TX
7. recover JMS name1 (returns no Xid of course)
8. recover DB name2 (returns name2,Xid2)
9. Don't want to print no XA resource to recover  name1,Xid1, if we can match up name1 reliably we can infer that JMS name1 committed pre crash
