Yeah, sure! This means all logs need archiving at the same time. There are two reasons for this happen: either there is a 'burst' of transaction volume or the archive log disk is full, and Oracle can't archive any log In the latter case you can archive a log manually to a different destination. Usually, the problem is a combination of the two problems together. When I need to create a database I usually start off with groups, with members of 5M, and I make them bigger when Oracle starts generating the messages below. Please note: when this happens the system will hang until the condition is resolved. It is not slowing down, apparently still something happens that resolves the current situation.

I have 2 groups, each 8M, I added a third group 8M, but still get the warnings.
