HA setup : Shared storage
  

Shared storage

It is recommended that the following directories are synchronised between the application servers:
/conf
/media
/custdeploy
/deploy/wookie.war/wservices
 
Synchronisation can be either a manual process, or automatic, by way of shared storage mechanisms. This will be a design choice, based on the requirements and system usage. For example, the contents of the /conf folder may never (or rarely) be touched on a production system, once deployed, and can be copied manually. If widgets or custom applications are not utilised then the /deploy/wookie.war/wservices and /custdeploy directories do not need to be synchronised.
To utilise shared storage on the application server instances, NAS (Network Attached Storage) should be mounted to the same location on both servers and symbolically link the required folders to this mount point (using mklink to create symbolic links on Windows file systems).
Symbolic links on Windows for the directory /media are only supported on Orchestra 6, Hotfix1, and later.
Alternatively, on Windows, DFS replication can be used to synchronise the directories.
