Chapter 3. Administration 53
Y ou must consider several factors when you use large object support:
/SM590000The report must be indexed with an indexing program that generates a large object by 
dividing large documents into smaller parts and defining the indexing information that is 
used to retrieve the documents. 
/SM590000The amount of data per page and the number of pages that you divide documents into 
affects retrieval and viewing response time. The number of bytes per page typically 
dictates the number of pages that you can divide documents into. In general, the larger the 
page size in bytes, the smaller the number of pages that you can divide your documents 
into. For example, if the average page in the document contains 2.5 KB of data, choose 
100 - 1000 pages per Large Object (LO) segment; if the average page in the document 
contains 50 KB of data, choose 1 - 100 pages per LO segment. 
/SM590000The capacity of your network and the traffic in the network might determine the number of 
pages that you need to divide your documents into. Larger document sizes (large byte size 
even when compressed) require more network bandwidth (or more time if the bandwidth is 
not available) to transfer from a Content Manager OnDemand server to a client. The 
number of users that are concurrently accessing Content Manager OnDemand and the 
sizes of the documents that are being retrieved determine the overall load in the network. 
/SM590000Response time requirements. The goal of Content Manager OnDemand large objects is to 
provide better performance and usability. Large object support clearly provides enhanced 
usability. However, you must implement large object support so that dividing your 
documents into parts provides better overall performance than other methods of 
segmenting the input data. 
When you choose a large object, Content Manager OnDemand displays the Number of 
Pages field. Specify the number of pages that you want Content Manager OnDemand to 
divide documents into in the Number of Pages field.
To generate large objects, the indexer that is specified on the Indexing Information page must 
be AFP Conversion and Indexing Facility (ACIF), OS/390, or OS/400. When you select the 
Large Object check box, Content Manager OnDemand automatically adds the INDEXOBJ=ALL 
parameter to the indexing parameters (which causes the indexing program to generate the 
large object indexing information).
Exporting an application
It is not possible to export an application to application groups with different database fields or 
attributes. However, you can export applications to a different server if the application group 
on the target server is identical to the application group on the source server (the server on 
which the applications are defined). 
Ensure that no existing application has the same application ID in the target application 
group. For more information, see the section “Adding items to a server” in the IBM Content 
Manager OnDemand for Multiplatforms, V9.5, Administration Guide, SC19-3352.
Selecting font by line data graphical indexer
The font that is used by the line data graphical indexer to display a document can be changed 
from within the line data graphical indexer at the Content Manager OnDemand Administrator 
Client.
