requires the log file with the log serial number of 1, so the remaining log files in the original log sequence will not be available.The RESETLOGS operation creates a new form of the database, that is, a database with a new log serial number stream starting from 1.According to the above theory: SCN is a sequential data stream, which always increments during the database existence, while the log file sequence stream is also an incremental sequence, but it will be reset to 1 due to RESETLOGS, how
