Hi, I have just tried to use Ibatis 2.2 to test a single point of transaction with committing to two different databases (Sybase and MSSQL 2000) for some testings. My test program loads the two JDBC drivers (those non-XA type) and it really works (at the moment of daoManager.commitTransaction(), I killed the MSSQL Server session and it really rollbacked both transactions).
I am really amazing and found surprised, because I studied in university that a single of transaction with committing to more than one databases, it should require the combination of two-phase commits protocols and a transaction manager. XA type JDBC Driver should be used for two-phase commit protocol. And I think Ibatis can work as a role of transaction manager, but why using non-XA type JDBC driver can also do the same job. Hope some database experts refresh my concept. Thanks a lot, Raymond -- View this message in context: http://www.nabble.com/why-Ibatis-2.2-can-handle-multi-db-transactions-with-normla-JDBC-driver-tp18779667p18779667.html Sent from the iBATIS - Dev mailing list archive at Nabble.com.
