Fault-Tolerant Subsystem Operations
Printers are connected through the NetWare network to
•
The print server
•
A workstation on the network
•
The network cable through a network interface card (NIC)
The LAN Print Spooler for NetWare is a print process in the Spooler subsystem. The
LAN Print Spooler for NetWare reads in information based on its configuration file
(FASTCNFG). (See the Spooler FASTP Network Print Processes Manual for more
information on configuring the print spooler file.) Using the information provided by the
LAN Print Spooler for NetWare, applications can send a print job directly to a NetWare
print queue. The NetWare print server then routes the print job to the specified printer on
the NetWare LAN. (Note that the LAN Print Spooler for NetWare does not function as a
NetWare print server.)
The Spooler subsystem no longer monitors a print job once the job is sent to a NetWare
print queue. The NetWare administrator has complete control of the print jobs residing
in NetWare print queues, including accessing and modifying print-job attributes,
deleting jobs from the queue, modifying the queue status, or changing the order in which
print jobs are serviced.
The NetWare print queues must be configured on the NetWare file server before they
can be used by the NonStop™ Himalaya S-series print process. To the Spooler, each
NetWare print queue is configured as a device. The LAN Print Spooler for NetWare
process uses a NetWare user identification to deliver jobs to the NetWare print queue;
therefore, a user identification and corresponding password must be configured on the
NetWare file server. The user identification and password allow the LAN Print Spooler
for NetWare process to log onto the NetWare file server to send jobs to the NetWare
print queue.
Fault-Tolerant Subsystem Operations
A processor switch occurs in a NonStop™ Himalaya S-series server when the backup
processor becomes the primary processor. The following data is checkpointed and
maintained across a processor switch:
•
Opens
•
Services being advertised
•
IPXMGR information on IPXPROTO processes
Data flows are not checkpointed. Where a processor switch occurs, the application must
recover data flows.
The following subsections discuss the fault-tolerant operations of the IPXPROTO and
IPXMGR processes and the NonStop™ IPX/SPX interfaces.
