To support user-level transaction and sub-transaction, after studying classical ARIES and MLR algorithms, we brought forward an improved transactional recovery algorithm for MOM named TRAMQ, and successfully employed it in ISMQSM.

• 另外，为了支持用户级事务和内部子事务，在研究了ARIES和MLR算法的基础上，本文提出了一个特定于消息中间件的改进的事务恢复算法TRAMQ，目前该算法已很好地应用到了ISMQSM中。
