Rules for configuring the system Introduction to administering Xprint V7.0

Servers

A server can control any number of supervisors. In practice, however, three supervisors is a good number.

Where possible the server should be defined on the host of the supervisors.

Note that in this case the availability of the printers depends exclu- ! sively on this particular host. If you distribute servers and supervisors

over several hosts, you must remember that both hosts must be available in order to use the printers.

Supervisors

Each supervisor must be controlled by a server.

A supervisor can control any number of printers; in practice, however, fifteen printers per supervisor are recommended.

The supervisor must be defined on the same host on which the printers are defined.

Automatic server and supervisor object creation

If no specific setting is used when creating a new device, Xprint V7.0 automati- cally generates default supervisors and server objects, following the rules hereafter:

A new supervisor is created for each 15 devices.

A new server is created for each 3 supervisors.

These defaults settings can be changed by means of 2 envivariables:

XP_SPV_BY_DFTSRV

Description: maximum number of supervisors by default server

Initialisation time: before xpadd -dev

Possible values: from 1 to 15

Behaviour if unspecified: 3 is used

Behaviour if a value larger than 15 is specified: 15 is used

XP_DEV_BY_DFTSPV

Description: maximum number of devices by default supervisor
