群集日志没有发现检查点记录。
如果服务器处于排出模式下时遇到另一条日志检查点记录，那么它会回到缓冲模式。
If another log checkpoint record is encountered while it is in drain mode, it goes back to buffering mode.
一旦存档检查点在RSS节点中完成操作，它会停止应用任何其他的日志记录，让服务器保持正确状态，以便使用外部实用工具复制数据块。
Once the archive checkpoint is completed in the RSS node, it will stop applying any other further log records, leaving the server in the correct state to copy the chunks by an external utility.
一旦将检查点传输给rss节点，它会开始将来自主要服务器的日志记录暂存到RS次要服务器上的日志暂存区域中。
Once a checkpoint is transferred to the RSS node, it will start staging the log records coming from the primary in a log staging area at RS secondary server.
检查点定义数据库在加载流程中成功处理指定数量的记录时的时间点。
A checkpoint defines a point during the loading process at which the database has successfully processed a specified number of records.
当发出“AlterTablespace ts_nameEndBackup”时，在联机备份数据文件的的文件头中再次记录了检查点scn。
When Alter Tablespace ts_name End backup is issued, again a checkpoint SCN is recorded at the headers of online backup data files.
次要服务器处于排出模式或缓冲模式下时，可能会遇到另一条检查点日志记录，您会看到挂起的检查点在增加。
The secondary may encounter another checkpoint log record while it is in drain or buffering mode, and you may see pending checkpoint increased.
检查点频率是可配置的，但文档记录是每25毫秒出现一次。
Checkpoint frequency is configurable but documented to occur every 25 ms.
exec-step后的 *stopped消息是一个OOB记录，它提供关于断点、检查点和目标暂停或结束原因的信息。
The *stopped message after -exec-step is an OOB record that provides information about breakpoints, watchpoints, and why the target has halted or finished.
该策略不会产生多米诺效应且不需要记录任何进程间消息，缩短了进程阻塞消息发送时间，且检查点生成过程中使进程得以同步，因此算法具有较好性能。
The strategy can avoid domino effect and log message between processes, which makes the blocking message-sending time shorter, and synchronizes processes in the process of checkpointing.
检查点将为参加者记录到达时间，并提供紧急支援服务。
