text: **13.1.3 System management**
  
  For effective system management, set the appropriate value for**ARS_NUM_DBSRVR**and create 
  the correct file systems for various Content Manager OnDemand components. 
  
  **ARS_NUM_DBSRVR**
  The**ARS_NUM_DBSRVR**parameter is set in the ars.cfg file. This parameter is the maximum 
  number of threads that are concurrently open between the Content Manager OnDemand 
  library server and DB2. Typically, this value is set to a number between 4 - 30. This number 
  must be large enough to support all of the concurrent database requests from all users and 
  clients and Content Manager OnDemand commands and daemons, such as**ARSLOAD**,**ARSDOC**, 
  **ARSDB**,**ARSMAINT**, and**ARSADMIN**. This number must not exceed the number of DB2 batch 
  connections (**MAXDBATS**for z/OS and**MAXAPPLS**for Multiprocessing (MP)). The number of DB2 
  batch connections must be greater than the**ARS_NUM_DBSRVR**, plus all of the other connections 
  that are required by all DB2 applications that you defined in your DB2 configuration. 
  
  For systems that are running several large load jobs in parallel, or for systems with large 
  numbers of active users, increase this parameter from the default of 4.
