The transaction log is stored as a sequential disk file (or sometimes in a raw partition) and will generally only be written to, not read from, except in the case of rollback or recovery.
事务日志存储为连续的磁盘文件(有时存储在原始分区中)，并且一般只是用于写入而不用于读取，回滚或恢复的情况例外。
This process reads log files during rollback, restart recovery and roll forward.
此进程在回滚、重启恢复和前滚期间读取日志文件。
This supports simple rollback and recovery, but can impact performance if the application being invoked can't respond quickly.

Keeping a migration plan, documenting changes to stable states, having a backup solution, and having rollback and recovery instructions will help minimize your downtime and maximize your results.
最佳策略是制定一份详细的迁移计划，记录对稳定状态的更改，选择一种备份解决方案并了解回滚和恢复说明，这一切将有助于最小化停机时间，从而最大化您的工作成果。
If the application server should fail between calling prepare and commit or rollback, then transaction recovery needs to take place when the server restarts.
如果应用服务器在调用prepare和commit、rollback之间失败，那么在服务器重启时需要进行事务恢复。
