I have two database servers at different location with different domains.
I have configured Oracle Advanced Replication b/c both servers.
Due to the virus, i had to build my one database server again..
When i configured replication again...I am receiving this error.
"ORA-12638: Credential Retrieval Failed"

Transactions from one side are pushed to other side but from that sides transactions are not applied in my new side.

Kindly solve my problem if any one knows.
