此进程在回滚、重启恢复和前滚期间读取日志文件。

Because you can change the log path location, the logs needed for roll-forward recovery may exist in different directories or on different devices.

因为您可以更改日志路径位置，所以前滚恢复所需的日志可能会在不同的目录中或在不同的设备上存在。

youdao

Archive logs that are currently stored in the database log path directory are not moved to the new location if the database is configured for roll-forward recovery.
