text: **1.3 Content Manager OnDemand server and its components**
  
  On IBM z/OS® and Multiplatforms (MP) systems, the Content Manager OnDemand server 
  can be implemented as a library server and one or more object servers that are on one or 
  more nodes that are connected to a Internet Protocol network. For the Content Manager 
  OnDemand system overview, see Figure 1-1 on page 5. 
  
  **1.3.1 Library server and object server**
  
  A Content Manager OnDemand*library server*maintains two sets of database tables: 
  
  (cid:2) The first set of database tables contains indexes about the reports that are stored in the 
  Content Manager OnDemand Archive. 
  
  (cid:2) The second set of database tables contains information about the objects that are defined 
  to the system, such as users, groups, printers, application groups, applications, folders, 
  cabinets, and storage sets. 
  
  The database manager provides the database engine and utilities to administer the database. 
  The library server processes client logons, queries, and print requests and updates to the 
  database. The major functions that run on the library server are the request manager, the 
  database manager, and the server print manager. 
  
  A Content Manager OnDemand*object server*maintains documents on cache storage 
  volumes and an ASM. ASMs, such as Tivoli Storage Manager on Multiplatform systems, OAM 
  on z/OS systems, or ASM on IBM i systems, allow hierarchical storage management 
  techniques to be applied to the stored documents. An object server loads data, retrieves 
  documents, and expires documents. The major functions that run on an object server are the 
  cache storage manager, data loading and maintenance programs, and optionally, the ASM.
