Hello @Vandy ,

Thanks for reaching out.

In Qlik Replicate , there is stream position value on the source, usually the SCN, LSN, or POS etc which allows Replicate tasks to resume from the last broken point, it's stored in Replicate repository, or target database (configurable). 

1- Yes, if a task is stopped and resumed, them it will resume from the last stream position (In Oracle it's SCN) automatically. Certainly you could startup the task from a given SCN/LSN/POS/Timestamp etc manually.

2- From last stream position, if it's available still.

3- In general Stream Position stores in Qlik Replicate Repository. Replicate utilizes SQLite DB as Repository.

4- Yes or No. Yes - the information is stored in SQLite DB however you cannot access the SQLite DB directly; No - If you want to get these values, QEM is recommended.

Hope this helps.

Regards,

John.
