When installing omg-aggmgr note the following:

1.In ogs.rb add variable that represents root directory of the application

DEF_VAR_PATH ="/usr/share/omf-aggmgr-5.2/omf-aggmgr"

2. In method register in ogs.rb add root path to server content

   #Lets add root path to static server/service content
   cfg.merge!('varPath' => "#{DEF_VAR_PATH}")
