Hi Sudhir,
I just restarted the SMP Server service and looked at the startup log in order to check if the key pair was loaded successfully. Below is the log results on key pair:
10:12:59 01/09/2015: 1 initial threads. Threads will auto-scale.
10:12:59 01/09/2015: Event: 0, 2, Loading the Agentry Runtime's public/private key for password exchanges.
10:12:59 01/09/2015: Event: 0, 2, Key pair loaded successfully.
I've also just looked at the event log and there seem to be no errors worth noting.
Regards,
Thulani
