Information in this document applies to any platform.
Using Oracle Database Server 11gR2 Standard Edition,
after implementing various legacy Advanced Security Option (ASO) features (e.g. Kerberos, Native Encryption, TCPS/SSL, RADIUS),
various errors are received when connecting via the listener:
ORA-12657: No algorithms installed
ORA-12649: Unknown encryption or data integrity algorithm
ORA-12637: Packet receive failed
TNS-12557: TNS:protocol adapter not loadable
TNS-12560: TNS:protocol adapter error
TNS-00527: Protocol Adapter not loadable
The Oracle documentation specifies:
This is true from a licensing point of view. Technically, the 11gR2 Standard Edition (SE) binaries are not linked with SSL, Kerberos and Radius adapters; these adapters are not enabled out-of-the-box on 11gR2 Standard Edition.
To compare, here is the output from an 11gR2 Standard Edition installation running on Linux:
(Note the lines reading "Kerberos v5 authentication" and "RADIUS authentication", which do not appear in the Standard Edition output.)
