Multiprocessing with Cognos Transformer Server

By upgrading to a multi-CPU server and running multiple instances of Cognos
Transformer in parallel, you can significantly decrease the build time for your
largest cubes. In a model that generates more than one cube, the overall creation
time is reduced to the time taken for the slowest cube to build.
Use th following strategies:
v Give each Cognos Transformer process its own CPU. Because each instance uses
system resources independently, ensure that each one has sufficient memory, I/O
bandwidth, and disk space.
v Provide each Cognos Transformer instance with its own configuration files.
v Do not share the locations of DataWorkDirectory and ModelWorkDirectory among
multiple instances.
v Add an ampersand (&) to the end of the UNIX or Linux command line to begin
your first process in background mode. For example, use
