Another successful recovery system will involve sustaining transaction logs. These logs serve as information that seize all variations made for the database.

Every time that a datafile or an online redo log file is included to, renamed in, or dropped from the database, the Management file is up to date to replicate this Actual physical structure change.

Restoring from geo-redundant backups could probably bring about data reduction in specified scenarios because Azure Geo-Redundant Storage (GRS) replicates data asynchronously into a secondary location. There is certainly some latency associated with the replication method, but the exact latency can differ based upon various elements, such as the distance amongst the main and secondary areas and The existing community circumstances.

In the event the fix crashed hard drive datafile that can't be composed to is inside the Technique tablespace, the file is just not taken offline. Instead, an error is returned and Oracle shuts down the database.
