Oracle 11 Redhat Linux 4 Physical DG. Anyone ever seen this? My standby stopped advancing. So I did what I always do crashed the recovery and ran it manually. This usually highlights the problem or even cures it. But All I get is one archived log applied then it froze again. I have done this several times and each time the 'stuck' log is applied almost immediately then the db apply stops again. No errors just a lot of silence! -- Howard A. Latham
