QUESTION:

The Vertica database has been moved from a virtual machine to a physical server with a different host name. What changes need to be made on the Data Aggregator so that it recognizes the new server?

 

ANSWER:

Update the dbHostNames field in the file /opt/IMDataAggregator/apache-karaf-2.3.0/etc/dbconnection.cfg on the DA. It is also a good idea to check the DA's /etc/hosts file to be certain the new Vertica server is listed properly.
