Spool Server

Definition

The spool server is an SAP application server that provides spool processing. It therefore

requires at least one spool work process.

SAP Note 108799 in the SAP Service Marketplace explains how many spool workprocesses you should configure for each server.

A spool server processes the data for transfer to the spool system of the operating system. You

can set up a spool server by adding the profile parameter rdisp/wp_no_spo to the instance profile

of the corresponding server (Administration p CCMS p C onfiguration p P rofileM aintenance) and entering the desired number of spool work processes.

Setting or Changing Properties of a Spool Server

You can enter additional attributes and administration information for spool servers.

To do this, call transaction SPAD (T ools p CCMS pSpool p Spool Administration), and, onthe Devices/ S ervers tab page, choose the Spool S ervers pushbutton. The list of defined spoolservers appears. If you double click the relevant spool server, a window showing the attributes of

the spool server appears.

The following example shows the attributes for a mass printing server:



You can enter or change the following attributes in this window:

y Server Name: You can enter a description of the spool server in the long field of theServer Name area.

y Server Class: Choose a suitable entry, depending on the intended use of the server, from theinput options for the server class field, such as production printing, mass printing, and so on.

The classification of the spool server helps you to realize your planned printing architecture, that is,to assign newly defined output devices to the corresponding spool server. If you specify the spoolserver in a device definition, the spool system compares theclassification of the output deviceto theclassification of the server. If they do not match, then the spool system warns you.

If you are preparing to assign a mass printer to a time-critical production server, then thespool system warns you of this disparity.

y Alternative server: You can specify a ³replacement printer´, the alternative server, for a spoolserver. The alternate server takes over the processing of output requests if the original server isdown or unavailable. For more information, seeAlternative Server .

y Allow Load Balancing: You can define whether the output processing workload of a server may

be distributed among its alternate servers. By default, load balancing is deactivated. Instead, thespool system ensures that output requests are printed in the order that they are generated.

y Logical server: You can define spool servers as logical servers. A logical server is a name thatcan, in turn, stand for one or more logical or real servers (a real spool server is a server thatactually has spool work processes and can run in the SAP System).

Using logical servers, you can transport a complete printing architecture to another system withonly minimal changes. To activate printing in the target system, you only need to edit theassignment of the logical server. You can do this using theM apping field. For more information,see Logical Spool Servers.
