IC75231: AES FAILS ON JCC DUE TO GATEWAY SENDING THE INCORRECT INFORMATION

APAR status

  • Closed as program error.

Error description

  • The following error message is returned to the application from
    the JCC driver and viewed on the screen:
    
    "Connection authorization failure occurred.  Reason: Encryption
    Algorithm is not supported. ERRORCODE=-4214"
    
    This message is receveived because the TCP/IP connection is lost
    on the DB2 Connect gateway system. This connection issue causes
    the DB2 Connect gateway to send back a request to reestablish
    the
    connection, however it does so with an incorrect encryption
    algorithm that is stored in the DB2 Connect buffer. This causes
    the connection to
    fully fail and send the -4214 error message back to the
    application.
    
    The error message is defined in the DB2 9.5 Information Center.
    
    This APAR will fix DB2 Connect so that the Advanced Encryption
    Standard (AES) algorithm will be returned correctly to the
    database server.
