Symptoms


Using DG4DRDA 11.2 with SSL (Secure Sockets Layer) connections and a self signed certificate gives the error -

ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Oracle][ODBC DB2 Wire Protocol driver]SSL passed certificate is self signed and the same certificate cannot be found in the list of trusted certificates. {HY000,NativeErr = 7550}[Oracle][ODBC DB2 Wire Protocol driver]SSL Negotiation failed. {08001}
ORA-02063: preceding 2 lines from DB_LINK


A DG4DRDA debug trace shows the following -
