Once that is done pull the certificate from eemserv1 and add to the cacerts on this path /opt/CA/SharedComponents/iTechnology/_jvm/lib/security/cacerts
 
keytool --list --keystore /opt/CA/SharedComponents/iTechnology/_jvm/lib/security/cacerts

keytool -import -noprompt -trustcacerts -alias eventproc01 eemserv1 -file eventproc01 eemserv1 .pem -keystore cacerts -storepass xxxxx{code}
