Effective in version 6.1, you do not have to share the
ILM_HOME/webapp/file_archive/
directory between multiple ILM engine instances, even when the File Archive Service and the ILM engines are on the same server. Previously you were required to create symbolic links to the
ILM_HOME/webapp/file_archive/
directory for each ILM engine you used to archive data to the optimized file archive.
