| 2. | In this thesis , we studied several key issues of distributed recovery management
本文给出了jts服务恢复管理子系统jrecovery的设计和实现。 |
| 3. | By far , the research on recovery management in database systems is relative thorough
目前，数据库的恢复管理研究已经比较深入， ibm研究中心的c |
| 4. | Recovery management is the essential problem of transaction process . recovery manager is very important for maintaining the acid property of the transaction
恢复处理是事务处理的核心问题之一，恢复处理器对保持事务的acid特性起着关键作用。 |
| 5. | However , the research on the recovery management in distributed transactions is still very significant and the distributed computing environment in j2ee brings higher requirement for transaction recovery
分布事务的恢复处理研究仍极为重要， j2ee分布计算环境对事务恢复研究提出了更高的要求。本文针对这些问题展开研究。 |
| 6. | And distributed transactional recovery aims to ensure the durability of the objects on different servers and the atomicity of the failures . for distributed transactions , the challenge of recovery management is to recover the failures occurring during the two - phase commit protocol
而分布事务恢复的功能是保证服务器上对象的持久性和故障原子性，关键是针对两阶段提交的各种问题实现恢复。 |
| 7. | Thirdly , the thesis focuses on three issues of the fault tolerance management which must be addressed by the fault tolerant middleware : object replication , fault detection and notification , state logging and recovery . accordingly , three mechanisms of replication management , fault management , logging and recovery management are proposed
3 、容错中间件的主旨是为基于中间件开发的分布式应用提供一个容错支撑平台，因此必须为应用解决对象复制、失效检测和通告、日志和恢复等容错管理问题，它们分别对应于复制管理、失效管理、日志和恢复管理。 |
| 8. | During recovery management , the transaction information search becomes troublesome since the details of log files is masked . jrecovery tries to optimize the search procedure . we give the algorithms for the restoration of active transactions " list and the transaction status searching and the optimizations of the two algorithms
Jrecovery试图通过虚拟日志信息搜索算法的优化来解决此问题，论文给出了jrecovery对活动事务表重建算法和事务状态搜索算法的优化，论文也应用设计模式，以简化恢复管理子系统的设计，提高从其可重用性。 |
