该策略不应该用在线事务处理(on - line transaction processing, OLTP)环境，因为它不可能进行前滚恢复。

This strategy should not be a choice in an on-line transaction processing (OLTP) environment since roll-forward recovery is not possible. Figure 1 below illustrates circular logging.

例如，由于文件系统不是事务型的，因此不支持按永久性 WebSphere MQ 消息的方式进行文件的事务处理，但支持恢复处理。

Transactional processing of files is not supported in the way that it is for persistent WebSphere MQ message for example as the file systems is not transactional but recovery processing is supported.

同时，本文还重点讨论了模型中的分布式事务处理和分布式恢复的实现机制。

Besides, This paper also discusses the implementation mechanism of distributed transaction processing and the distributed recovery of the model.
