Chapter 1. Overview and concepts 11
On certain platforms, you can also configure your Content Manager OnDemand system with 
a library server on one node and one or more object servers on different nodes. These nodes 
can run the same or different operating systems. This configuration is known as a distributed 
library/object server system. The distributed library and object server configuration supports 
the caching of documents on different servers. Y ou can add an ASM to one or more of the 
object servers to maintain documents on archive media that are attached to different servers. 
One of the key requirements in a distributed library or object server system is that all of the 
distributed components must be at the same Content Manager OnDemand code level.
1.3.2  Content Manager OnDemand server components
A Content Manager OnDemand server environment contains several components:
/SM590000A request manager provides client, network, and operating system services, security, and 
accounting. The request manager is on the library server.
/SM590000A 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.
/SM590000Database 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.
/SM590000A 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.
/SM590000An 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.
/SM590000If your Content Management OnDemand System is installed on an MP platform and you 
need to download documents from a z/OS system, you can use a download facility to 
automatically transfer spooled files to the MP server. As a preferred practice, use 
Download for IBM z/OS, which is a licensed feature of IBM Print Services Facility™ (PSF) 
for z/OS. Download for IBM z/OS provides the automatic, high-speed download of Job 
Entry Subsystem (JES) spooled files from an z/OS system to Content Manager 
OnDemand servers. The download facility is not applicable to the IBM i server. 
/SM590000Data indexing and conversion programs can create index data, collect required resources, 
and optionally convert Line Data reports to AFP data. Content Manager OnDemand 
provides several indexing programs:
–T h e  Advanced Function Presentation (AFP) Conversion and Indexing Facility (ACIF) 
can be used to index IBM z/OS Line Data, ASCII data, and AFP files, collect resources 
that are necessary to view the reports, and convert Line Data files to AFP data. 
–T h e  IBM OS/390 Indexer is a high-performance indexer that can be used to index 
various data types and is available on both IBM z/OS and IBM AIX®. 
–T h e  IBM OS/400 Indexer can be used to index various data types. It is the most 
common Content Manager OnDemand indexer for IBM i spooled files. 
–T h e  Content Manager OnDemand PDF Indexer can be used to create index data for 
Adobe Portable Document File (PDF) files. 
–T h e  Content Manager OnDemand Generic Index File Format can be used to provide 
index data for almost any other type of data, such as HTML documents, 
word-processing documents, and Tagged Image File Format (TIFF) files.
