Although a different branch office indeed seems to have replaced it for a couple pSeries machines with AIX and some Veritas clusters but I don't know what the purpose of this installation is. But in general I'd think that mainframes are still dominant here. From what I've heard, all transactions are also printed, in real-time, on paper (by high-speed lineprinters), so that even when the machines fail completely and lose transaction data, there is still a hardcopy log. At least I hope that this is (still) true. mkb.
