Unable to add the Data Aggregator as a data source

When adding the Data Aggregator as a datasource and testing it, we see "Data source communication failure".  In the wrapper.log we see "Returning DS_COMM_FAILURE result"

A communication problem between CA Performance Center and the Data Aggregator


DS_COMM_FAILURE is a very generic error but it usually means the /etc/hosts file is mis-configured on either CA Performance Center or the Data Aggregator or both.  Make the necessary changes to the /etc/hosts file and attempt to add the Data Aggregator again.  

Another possible cause of a communication failure would be the firewall is running on one or both systems.  Run the following command on each system: /etc/init.d/iptables status.  If you get any output then run /etc/init.d/iptables stop to stop the firewall.  Then attempt to add the Data Aggregator again
