Oracle : Ошибка ORA-28871

"Peer certificate chain is incomplete."
*Cause: The peer certificate chain presented was incomplete because it did not
end with a self-signed root certificate.
*Action: Refer to Oracle Wallet Manager documentation to find out how to open
your wallet and ensure that:
1. the certificate authority's root certificate is self-signed.
2. a certificate authority's certificate from your peer's certificate chain
is added as a trusted certificate in your wallet
