Hello,
I am wondering if anyone knows.
The First_change# column and Next_change# in v$log_history view
indicate the lowest SCN and highest SCN in the log file.
RECID STAMP THREAD# SEQUENCE# FIRST_CHANGE# FIRST_TI NEXT_CHANGE#
--------- ---------- ---------- ---------- ------------- -------- ------------
1528 528372470 1 1528 1086677 04-06-08 1086930
1529 528372582 1 1529 1086930 04-06-09 1087130
1530 528372973 1 1530 1087130 04-06-09 1087313
1531 528373064 1 1531 1087313 04-06-09 1087503
1532 528377304 1 1532 1087503 04-06-09 1087713
How come here, in the first record, the next_change# is same with
the first_change# in the next record?
For example shouldn't the first_change# in RECID=1529 be 1086931?
Thanks,
Beegirl

Hi,
Great observation! Yet, this is Oracle internal stuff. There is not much we as mere DBA mortals can do about it. I don't think the overlap is of great significance either.
Best regards.
