text: The cache file system must be owned by the Content Manager OnDemand instance owner. 
  The permissions on these file systems are important. On AIX servers, the cache file system 
  must be owned by the root user and the system group. On Linux, HP-UX, and Sun Solaris, 
  these file systems must be owned by the root user and the root group. You must ensure that 
  no other permissions are set. On AIX, the file system permissions need to be similar to the 
  following example: 
  
  drwx------ 3 root system 512 Sep 22 13:08 /arscache/cache1 
  
  **ARS.DBFS**
  The ARS.DBFS file location is identified in the ARS.INI file. It is read when the instance is 
  started. The ARS.DBFS file contains the file names in which Content Manager OnDemand can 
  store table spaces, and it determines the type of table space that Content Manager 
  OnDemand can create. Storing application group index data in a table space is optional, but 
  recommended. We also recommend that these file systems contain only Content Manager 
  OnDemand data and that each instance on the server has its own file systems on which to 
  store data. In general, the more table space file systems that you define, the better the 
  system performance is. When you use more than one table space file system, each table 
  space file system needs the same allocated disk space.
