i've marked them as resolved also.
i'm opening this new one as a follow up and as an observation:
We always restore using a script mentioning the time up to which we want to restore.
We have a daily backup scheduled for our production environment which starts at “21:00” and finishes between “4 am to 5:30 AM”.
We have always noticed while restoring on alternate clients, if the restore finishes anytime between “21:00 and 5:30 am” (the window when production backup is going on) the restore always errors out with the same error “INF - RMAN-06025: no backup of log thread 1 seq 682 lowscn 14956764 found to restore”. But if the restore finishes out of the backup window, it finishes without any issues.
so as you can see, though we've narrowed down the cause, we still haven't found the root cause of the problem. hoping someone can shed light on this.
we are still investigating from our side.
