This knowledge article reflects updated product names. Oracle Blockchain Platform Cloud Service (OBPCS) was formerly known as Autonomous Blockchain Cloud Service (ABCS). Please refer to "Name Change for PaaS services during Jan 2019 <Document 2493395.1>" for the full list of recently renamed PaaS services.

How does OBPCS (Oracle Blockchain Platform Cloud Service) updates records to rich history database tables? ("*_hist" ,"*_state", "*_last" )?

E.g. If rich history database is down for one day due to any reason like maintenance etc, When the connection will be restored will the entries that have been made during the downtime be inserted again or only the latest one will be inserted?

Is it needed to delete all the tables to get all the entries?
Another scenario would be like if rich history database got corrupted due to some reason, when user create a new connection will the old entries be lost? Or will user be able to recover them?
