Hi,
My main database server was not being replicated on standby server. In
standby's logs I am getting :
2011-06-16 16:22:03 IST FATAL: database system identifier differs
between the primary and standby
2011-06-16 16:22:03 IST DETAIL: The primary's identifier is
5618757375637716504, the standby's identifier is 5618757422882348667.
Does anybody have any idea ?
Regards,
Sanjay Rao
