OHS12c - Update the ohs instance level configurations

As OHS12c is associated with Weblogic server and if the corresponding Weblogic setup as per EDG (Enterprise Deployment Guide) then you have to follow below guidelines if you are updating OHS configurations.

1. Make sure to update the configurations at aserver path (i.e. Admin Server location) and restart Admin Server. Then the changes will be propagated to mserver path (i.e. Managed Server/OHS instance locations)
2. If you directly apply any change at mserver path, then those changes will available till you restart the Admin Server. 
3. After that your Admin Serer will propagate the Admin Server copies of httpd.conf, mod_wl_ohs.conf/other all configurations to mserver path. As a result your local changes which are available at mserver path will be lost.

Conclusion: Make sure to update the configurations at aserver path.
