unsupported encryption/crypto-checksumming version

Cause

Encryption/crypto-checksumming version used by remote is not supported by this configuration.


Action

Upgrade the remote client/server to use higher version of encryption/crypto-checksumming adapter. If the support for lower version is needed, add the following to sqlnet.ora file:

CLIENT: (to allow connections to weak servers) sqlnet.allow_weak_crypto = true SERVER: (to allow connections from weak clients) sqlnet.allow_weak_crypto_clients = true

CAUTION: This parameter allows insecure network connections between a client and server. Hence, it must not be used unless the remote endpoint cannot be updated to run the higher version of the encryption adapter. User is strongly advised to carefully consider the implications of this parameter before configuring it to allow weak connections.
