Figure 12-4   Horizontal and vertical scaling with multiple LPARs
This scenario is in organizations with large systems, such as AIX or z/OS, that are installed 
and that have enough available capacity to support the required Content Manager 
OnDemand workload. One advantage of this configuration is that you can control the priority 
of work and computer resource distribution to each of the LPARs, such as the number of 
processors or the processing priority (depending on the computer system/operating system 
architecture) that is allocated to each of the LPARs. So, for example, load jobs can be 
assigned a low priority during the day when the focus is on data retrieval and a high priority 
during the night when the focus is on data loading.
This setup supports horizontal scalability by using multiple technologies as appropriate. The 
main constraint is that clients must have access to all systems through TCP/IP . 
12.2.6  Multiple server configuration rules
The following general rules apply when you configure multiple Content Manager OnDemand 
servers. In all cases, for additional guidance, see the appropriate Content Manager 
OnDemand documentation or contact Content Manager OnDemand Lab Services.
/SM590000Each Content Manager OnDemand server has its own set of configuration files. 
/SM590000The parameters in all configuration files must be set so that all of the servers are part of 
the same instance. 
/SM590000The Content Manager OnDemand clients connect to the IP address listening port of the 
Content Manager OnDemand server (library server module). 
/SM590000The documents are retrieved from the various object servers based on the location 
information that is returned by the library server. This retrieval is transparent to the client 
systems.
/SM590000Parallel load processes must have separate temp directories.
Figure 12-5 on page 292 depicts this configuration type.
