Mackie V7.0 manual Procedure

Configuring Xprint V7.0 Administering hosts

As a guideline, experience has shown that there is a practical limit of 50 potential masters/slave hosts in a single domain. If there are too many potential master/slave hosts, it is difficult to keep all the databases updated. If more than 50 hosts are needed then parasite hosts can be defined, or the domain can be divided into a number of smaller domains.

Parasite hosts import the database from their supporting host (potential master or slave) by means of a file sharing utility (e.g. NFS) which needs to be set up by the administrator. Parasite hosts depend on the supporting hosts, as Xprint V7.0 cannot run on the parasite if it hasn’t been started on the supporting host.

If you divide the original domain into several smaller domains, printers that are now in a different domain can be accessed by prefixing their names with a gateway name. If the devices must be accessed with the same name from every host, independently of which host they belong to, then this can be achieved by replicating the definition of the network devices in each domain. A physical printer can then be defined with the same logical name in each network. A user can then access the printer by using this name from any host in the system

Procedure

Once at least the primary master host is defined, you can add all the other systems to Xprint V7.0. The order in which you configure them also determines the order of the host hierarchy. If one computer is entered after another computer it also ranks below this one in the hierarchy (see section “Xprint V7.0 objects” on page 9).

To add a new host to the Xprint V7.0 configuration, you must perform steps on both the active host and the host to be added. First the new host must be regis- tered in the existing Xprint V7.0 configuration, then it can import the Xprint V7.0 database and become part of the Xprint V7.0 network.

To configure a new host, proceed as follows:

●Log in to an active host. If the Xprint V7.0 administrator is defined as a user there, log in as the Xprint V7.0 administrator, otherwise as root.

●Enter the following command to add the new host to the database: xpadd -hoshost_name -rehost_type [-shsupporting_host]

where host_name is the name of the relevant host and host_type the value you have entered in the worksheet. The option -rehost_type (re stands for responsibility) may be omitted for potential masters. If the value PARASITE is specified for host_type, the value supporting_host for -shspecifies on which system the database for this parasite host can be found.
