Description:
In many MQ SSL cases, BW sends ClientHello to MQ server and then comes the following lines. There is no ServerHello back from MQ server which makes it hard to find the root cause.

Thread-157, handling exception: javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
Thread-157, SEND SSLv3 ALERT:  fatal, description = handshake_failure

Error "SSL peer shut down incorrectly". "Remote host closed connection during handshake" when BW connects to MQ and fails right after BW sends ClietHello.

The error means that the SSL Server is not properly configured to accept SSL CLientHello. i.e, the SSL server fails to initialize itself to use SSL. For MQ server, the keystore configuration on the SSL file of the queue manager is wrong. Note that a correct format resembles, "C:\IBM\WebSphere MQ\Qmgrs\QM_for_TIBCO3\ssl\NoOID\key" in which "C:\IBM\WebSphere MQ\Qmgrs\QM_for_TIBCO3\ssl\NoOID" is the folder where you save the "key.kdb" file. Many times, you miss "\key" after the full folder path "C:\IBM\WebSphere MQ\Qmgrs\QM_for_TIBCO3\ssl\NoOID" which would result in the error.

See the attached (Filename: SSL_peer_shut_down_incorrectly.txt) for reference.
