I'm using 10g and exercising backups through resetlogs. Command: select INSTANCE_NUMBER, INSTANCE_NAME from v$instance; INSTANCE_NUMBER INSTANCE_NAME --------------- ---------------- 1 XYZ_SID I issued point-in-time recovery followed by alter database open resetlogs; select INSTANCE_NUMBER, INSTANCE_NAME from v$instance; INSTANCE_NUMBER INSTANCE_NAME --------------- ---------------- 1 XYZ_SID SQL select SEQUENCE#, resetlogs_change#, resetlogs_time from v$log_history Shows the sequence# reset to 1 and the sequence number in my archive file name has been reset to 1. My log_archive_format is set to xyz_sid_%S_%t_%r.arc. Below you can see that my sequence number was reset. Xyz_sid_0000000022_1_575652460.arc Xyz_sid_0000000001_1_578653176.arc I expected a new instance_number without resetting the sequence number. Is my assumption correct?
