A discussion many years ago asked "what happens if you run out of SCNs?" Curious minds still want to know or has this already been answered. joe _______________________________________ Joe Testa, Oracle Certified Professional (Work) 614-677-1668 (Cell) 614-312-6715 Interested in helping out your marriage?

It just resets the LSN (Log Sequence Number), thats why it is RESET-LOGS. You can advance SCN by ADJUST_SCN event (which goes only forward btw). You may consider FLASHBACKS to go back to the past. -Gopal On Wed, Jul 15, 2009 at 4:44 AM, hrishy <hrishys@xxxxxxxxxxx> wrote: Hi One of my environment makes use of streams and if i do a incomplete recovery using resetlogs the SCN would be reset.How do change the SCN to make it go back to what it was earlier. regards Hrishy
