Here is the procedure to resolve the connection issue between DA and Dr or the synchronization issue

1. Stop activemq and the dadaemon on DA.

/opt/IMDataAggregator/scripts/activemq stop

/opt/IMDataAggregator/scripts/dadaemon stop 

2. Move the data directory the data directory. 

mv/opt/IMDataAggregator/apache-karaf/data /opt/IMDataAggregator/apache-karaf/data_OLD

3. Move the kahadb file. 

mv /opt/IMDataAggregator/data/broker/kahadb /opt/IMDataAggregator/data/broker/kahadb_OLD

4. Move the local-jms-broker.xml file 

mv /opt/IMDataAggregator/apache-karaf/deploy/local-jms-broker.xml /opt/IMDataAggregator/apache-karaf/deploy/local-jms-broker.xml_OLD

5. Start the DA (note the dadaemon start will start the activemq process also)

/opt/IMDataAggregator/scripts/dadaemon start
