JTS服务恢复管理子系统的设计和实现

The Design and Implementation of JTS Recovery Manager

事务恢复处理在数据库应用和网络分布计算环境中具有重要作用。文章给出了一个JTS服务恢复管理子系统JRECOVERY,在分布事务环境下保持事务的ACID特性,可以在通信故障、操作系统和应用程序崩溃时提供全面的自动恢复。此外,JRECOVERY还提供了可重用的优化策略;目前,JRECOVERY已应用到分布事务管理器ISTX的实现中。

Transactional recovery plays an important role in database applications and in distributed network environ-ment.This paper proposes a recovery subsystem JRECOVERY for JTS service.JRECOVERY ensures transactions ACID property in present of communication,system or application failures.JRECOVERY adopts several reuse scheme in its design.Moreover,authors have successfully employed JRECOVERY in the implementation of a distributed transaction manager ISTX.
