text: When you use DB2 as the database, Content Manager OnDemand supports the use of 
  storage management subsystem (SMS) and automatic table space. See the DB2 
  documentation for the use of automatic table spaces. The use of the SMS table space allows 
  the operating system to increase the size of the table space, as required, during a load 
  process. 
  
  When you create an instance that uses table space, you must create an ARS.DBFS file. We 
  created the ars.dbfs file in our scenario. Each line in this file must contain the name of the file 
  system and the type of table space to be stored. The naming convention of these files is 
  shown: 
  
  /filesystem SMS 
  
  The name of the file system must identify the table spaces that can be created in the file 
  system. For example, the following line identifies the SMS table space file system: 
  
  /arsdb/db1/SMS SMS 
  
  These file systems must be owned by the database instance owner and the group. In our 
  scenario, the file system is owned by db2iadm1 and belongs to the sysadm1 group. See the 
  following example for the correct permissions: 
  
  drwxrws--- 4 archive db2iadm1 512 May 17 12:58 /arsdb/db1/SMS
