hi，你好，感谢反馈问题，关于停止增量备份，以及增量备份无法停止的问题排查，您可以参考下面步骤： 1.执行ALTER SYSTEM CANCEL BACKUP 或 ALTER SYSTEM CANCEL ALL BACKUP FORCE （3.1.2-ce版本不支持该指令）停止备份 2.查看任务是否已经停止：SELECT * FROM CDB_OB_BACKUP_PROGRESS，如果STATUS=COMPLETED则表示已经停止，如果STATUS=RUNNING，则表明任务未停止，如果备份任务还处在running状态，执行如下： a>查看当前的任务：SELECT * FROM __all_virtual_sys_task_status b>停止任务：ALTER SYSTEM CANCEL task XXX，其中XXX为上述 SELECT * FROM __all_virtual_sys_task_status中的group_task_id...

yes, thank for your suggestion, we confirm that drop primary key column is not support yet, and we will return right error msg in next 3.1.5 version.

你好，我先理解一下你的诉求： 1）日志备份滞后的排查手段 ； 2）日志备份的每次备份的起始时间以及状态 是这样吗？

你好，OB的归档不是个周期性任务，而是流式的在后台持续进行的事情。但是为了 一些优化比如对存储介质更友好，会聚合起来尽量大的IO，这个checkpoint_interval就是聚合的时间。我理解你的诉求是想要oracle那种周期性的归档，并且可以感知每次归档的时间开销？

Do you need to use the print_macro_meta function? This function is deprecated, but the code has not been deleted
