Chapter 7. Indexing and loading 165
Consider the following information about Table 7-1 on page 164:
/SM590000The Generic indexer requires the user to manually create an index file in the generic index 
format before the user starts the load process. The Generic indexer allows the capture of 
documents, index values, and resources that are identified to it. These documents, index 
values, and resources are then loaded into the Content Manager OnDemand archive and 
stored in the same manner as though they were loaded through any of the other indexers. 
An existing resource file can be loaded with a generic index file. 
For more information about the generic index format, see IBM Content Manager 
OnDemand - Indexing Reference, SC19-3354.
/SM590000The ACIF , PDF , XML, and OS/400 indexers all generate intermediate files. These files are 
then used to load the indexes and data into the Content Management OnDemand system.
/SM590000The OS/390 indexer creates the index data while it loads the indexes and data into the 
Content Management OnDemand system.
/SM590000Conversion refers to a conversion by the indexer. Other products integrate with Content 
Manager OnDemand that also convert data.
/SM590000Because of the architecture of PDF documents, large object support for PDF documents is 
not possible.
/SM590000Starting with V9.5, the PDF Indexer runs in the PASE environment on IBM i. PASE is a 
prerequisite on IBM i for V9.5.
/SM590000Starting with V9.5, the PDF Indexer is no longer supported on z/OS.
7.2  Getting started with PDF indexing
PDF is a standard that is specified by Adobe Systems, Incorporated, for the electronic 
distribution of documents. PDF files are compact. They can be distributed globally through 
email, the web, intranets, or CD-ROM, and viewed with Adobe Reader.
PDF is a data type or file format that is platform (hardware, operating system)-independent. A 
PDF file contains a complete PDF document that is composed of text, graphics, and the 
resources that are referenced by that document.
Two PDF file layouts are possible:
/SM590000Non-Linear (not “optimized”)
This file layout is optimized for space savings. Storing a PDF file by using a Non-Linear 
layout consumes less disk space than storing the same PDF file linearly. It is slower to 
access or display this type of layout because portions of the data that is required to 
assemble pages of the document are scattered throughout the PDF file, so the whole PDF 
file must be downloaded and accessed before the file can be displayed.
/SM590000Linear (“optimized” or “web optimized”)
In this file format, the PDF file is created in a linear (in page order) fashion. This file format 
allows the PDF viewer to start displaying the PDF document pages when they are 
downloading without waiting for the whole PDF file to be downloaded.
