MQ - AMQ9637: Channel is lacking a certificate

I wrote this post a wee while back, and those nice developerWorks folks have kindly published it for me: -

MQ - AMQ9637: Channel is lacking a certificate

...

In the context of configuring encrypted connections between WebSphere / IBM MQ and WebSphere Application Server, I'm currently building a scripted process to set up the infrastructure end-to-end, which I'm testing on a VM. For the record, I'm using IBM MQ 8.0.0.2 and WebSphere Application Server (WAS) 8.5.5.2.

...

At this point, I hit an issue. Instead of a happy message, I saw:

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake

More importantly, this is what I saw in the Queue Manager's log:

----- amqrmrsa.c : 930 --------------------------------------------------------
10/09/15 08:14:35 - Process(25255.10) User(mqm) Program(amqrmppa)
                    Host(bpm856.uk.ibm.com) Installation(Installation1)
                    VRMF(8.0.0.2) QMgr(TESTQM)
                   
AMQ9637: Channel is lacking a certificate.

EXPLANATION:
The channel is lacking a certificate to use for the SSL handshake. The channel
name is '????' (if '????' it is unknown at this stage in the SSL processing).

The remote host is '????'.

The channel did not start.
ACTION:
Make sure the appropriate certificates are correctly configured in the key
repositories for both ends of the channel.
