Вопрос ко всем не только к Валере.
Возможно ли сделать "Switchover" то есть трансформитовать Serv1 Source в Serv1 TARGET и Serv2 Target в Serv2 Source без использования probkup/prorest?
Я такое делаю с Ораклом (DataGuard). Понятно что одновременно обе стороны не могут быть Source (unless it is a GoldenGate), поетому в Оракле я сначала делаю из Ser1 Source - Serv1 Target. На какой-то короткий момент обе стороны Serv1 и Serv2 находятся в состоянии Target, a потом из Serv2 Target делаю Serv2 Source. Это называется Switchover. Такое есть в OpenEdge Replication ? I am just a curious person.

Я не силён в OE Replication но по моему там есть функционал смены ролей БД. Т.е. SOURCE БД падает и в этот момент TARGET БД становится SOURCE и по восстановлении упавшей БД начинает накатывать на неё изменения. Взято отсюда: OE Replication: User Guide. Transition.
IMHO.
