Solution:


export ACTIVEMQ_HOME=/opt/apache-activemq-5.8.0
export ACTIVEMQ_BASE=$ACTIVEMQ_BASE
ACTIVEMQ_OPTS_MEMORY="-Xms1G -Xmx1G"
export ACTIVEMQ_OPTS="$ACTIVEMQ_OPTS_MEMORY -XX:-UseParallelGC"
${ACTIVEMQ_HOME}/bin/activemq "$*"


VM Flags:

-Xms1G -Xmx1G -XX:-UseParallelGC -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote
-Djava.io.tmpdir=/opt/BROKERS/vass-desa-1/tmp
-Dactivemq.classpath=/opt/BROKERS/vass-desa-1/conf;
-Dactivemq.home=/opt/apache-activemq-5.8.0
-Dactivemq.base=/opt/BROKERS/vass-desa-1
-Dactivemq.conf=/opt/BROKERS/vass-desa-1/conf
-Dactivemq.data=/opt/BROKERS/vass-desa-1/data


Thanks
