text: **1.3.2 Content Manager OnDemand server components**
  
  A Content Manager OnDemand server environment contains several components: 
  
  (cid:2) A*request manager*provides client, network, and operating system services, security, and 
  accounting. The request manager is on the library server. 
  
  (cid:2) A*database manager*maintains the index data for the reports that you store on the system. 
  The database manager is a relational database management product, such as IBM DB2®. 
  The database manager is on the library server. 
  
  (cid:2) Database*control information*is information about the users, groups, application groups, 
  applications, folders, cabinets, storage sets, and printers that you define on the system. 
  The control information determines who can access the system, the folders that a user 
  can open, and the application group data that a user can query and retrieve. The database 
  is on the library server. 
  
  (cid:2) A*cache storage manager*maintains documents in cache storage. If the archive storage 
  server is accessed through the network, cache storage can be used for high-speed 
  access to the most frequently used documents. 
  
  (cid:2) An*Archive Storage Manager (ASM)*is an optional part of the system. The ASM is for the 
  long-term storage of one or more copies of documents on archive media, such as slower 
  disk or tape storage libraries.
