TNSLSNR for IBM/AIX RISC System/6000: Version - Production

Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=TCPS)(HOST=ip_address_here)(PORT=2484)))

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCPS)(HOST=hostname)(PORT=2484)))
ORA-28864: SSL connection closed gracefully
TNS-12560: TNS:protocol adapter error
TNS-00542: SSL Handshake failed
IBM/AIX RISC System/6000 Error: 28864: Error 28864 occurred.

In this case, the listener.ora file was configured to use a single TCPS address.
In other words, there were no other addresses (TCP or IPC) available for the listener.
