Figure 121: Load Balancing
For an output request for a spool server with load balancing (the setting
canbemadeforlogicalserversandspoolservers),thesystemdetermines
the server with the lowest load. The algorithm is recursive: The same
selection criteria are used on the mapping and the alternative server (both
could be logical servers themselves).
Sequential request processing (property of an output device) has priority
over the load balancing shown here (property of a spool server). This
means that output requests for an output device with sequential request
processing would not be distributed in accordance with the current load,
although assigned to a spool server with load balancing.
Transporting the Print Landscape
The concept of logical servers supports you when defining a consistent,
transportable print landscape. Logical servers can - unlike real spool
servers - have the same name in various SAP systems. In this way, you can
defineaconsistentSAPprintarchitectureinthedevelopmentsystemand
then transport it to other systems. After the transport, you must only adjust
the mapping of the logical servers to the spool servers of the new system.
