Maintaining the NetWare Server
Managing the Server
If a large number of packets is dropped because a server message indicates
that the server is busy, you may need to add another engine. Adding too
many engines, however, may decrease performance.
For more information, see “nxinfo” in Utilities Reference.
Checking Client Activity
Use this procedure at the HP-UX server console to configure the NetWare
watchdog (a connection-monitoring feature).
The watchdog sends packets to inactive connections and eventually logs out
connections that remain unresponsive. Use the watchdog variables to
configure how much watchdog information is recorded or displayed and
how long an inactive connection can remain unresponsive before it is logged
out.
Watchdogs can only be configured with the nwcm command. The
parameters watchdog are listed below.
console_display_watchdog_logouts. This variable controls messages sent
to the server’s display device when the watchdog logs out a connection.
“Yes” means messages are sent to the console. “No” means no messages are
sent.
If connections are unexpectedly losing their connection to the NetWare
server, set this variable to “Yes” until the problem has been corrected. The
default is No.
number_of_watchdog_packets. This variable specifies the number of
unanswered watchdog packets the NetWare server sends to a client before it
disconnects. Valid values are 5 to 100. The default is 10.
log_watchdog_logouts. This variable controls the creation of log entries
when a client is logged out by watchdog. “Yes” means the entry is logged
into SYS$LOG.ERR. “No” means the entry is not logged into
SYS$LOG.ERR or any other error file. The default is Yes.
delay_before_first_watchdog_packet. Delay before First Watchdog
Packet. This variable determines the time (in seconds) the server waits
without receiving a request from the workstation before sending out the first
watchdog packet to that workstation. The default is 296.
