Illustration strms057.gif shows that the inst1.net database and the inst2.net database do not share a computer file system. The inst1.net database runs a report at set intervals that adds the report files to the sales_reports directory object. This directory object corresponds to a directory on the inst1.net database's computer file system. Each time a new report is run, the report files in this directory are copied to a different directory on the inst2.net database's computer file system.

The illustration shows a file group repository in the inst2.net database with two versions of this tablespace set: sales_reports_v1 and sales_reports_v2. Other versions can also be added to the file group repository. The illustration also shows the directory objects on the inst2.net database's computer file system that store the files in these file groups. The sales_reports1 directory object stores the files for version sales_reports_v1, and the sales_reports2 directory object stores the files for version sales_reports_v2.
