• The Command Console can be started by running the following:
$ cd $RHINO_HOME
$ ./client/bin/rhino-console
Interactive Management Shell
[Rhino (cmd (args)* | help (command)* | bye) #1] State
SLEE is in the Running state
• The Web Console can be accessed by directing a web browser to
https://<hostname>:8443
. The default user-name is
“
admin
” and the default password is “
password
”.
The default port number to connect to can be changed during installation from the default "8443". The relevant install
question refers to the “
Management Interface HTTPS port number
”.

4.5 Setting the system clock
As with most system services, it is a bad idea to make sudden changes to the system clock. The Rhino SLEE assumes that time
will only ever go forwards, and that time increments are less than a few seconds. If the system clock is suddenly set to a time
in the past, the Rhino SLEE may show unpredicable behaviour.
If the system clock is set to a value more than 8 seconds forward from the current time, nodes in the cluster will assume that
they are no longer part of the quorum of nodes and will leave the cluster. Because of this, it is vitally important that system time
is only ever gradually slewed when it is being set to the correct time. It is recommended that the NTP (network time protocol)
service is set up to gradually slew the system clock to the correct time.
Use extreme care when manually setting the time on any node.
When using a cluster of nodes, it is useful to use
ntpd
to keep the system clocks on all nodes synchronised and to have all
nodes configured to use the same timezone. This helps, for example, for keeping timestamps in logging output from all nodes
synchronised.
The reader is referred to the
tzselect
or
tzconfig
commands on Solaris or Linux for instructions on how to configure the
timezone.
4.5.1 Configurating ntpd
The actual configuration of
ntpd
is beyond the scope of this document and the reader is referred to the documentation provided
with the
ntpd
package or on the Internet.
