Subject Re: ACS 4.5.1 mgmt DB HA - not working - invalid load balancing strategy
Date Thu, 11 Jun 2015 14:06:06 GMT
Actually, on another ACS installation, there is file:
 /usr/share/cloudstack-management/webapps/client/WEB-INF/lib/cloud-plugin-database-mysqlha-4.3.2.jar
(acs 4.3.2 :) )

But on this 4.5.1 there is no such file.

Is it possible that we didnt compile 4.5.1 in appropriate way ?

Thanks,
Andrija
