Localizing the appliance
This section describes setting localization options such as the keyboard layout and the time zone. The UI, however, cannot be localized.
Setting the keyboard layout
The console keyboard layout can be temporarily changed using the loadkeys
command to test that a keyboard layout works correctly.
To change the keyboard layout to a US layout, enter the following command:
[root@london01 ~]# loadkeys us [root@london01 ~]#
To change the keyboard layout to a UK layout, enter the following command:
[root@london01 ~]# loadkeys uk [root@london01 ~]#
After you have determined that the layout works correctly, you should make the change permanent. To do so, change the KEYTABLE, MODEL, and LAYOUT variables in the /etc/sysconfig/keyboard
file. For example, to change the keyboard layout to a US layout, use the following:
KEYTABLE="us" MODEL="PC105+inet" LAYOUT="us"
The keyboard mapping files can be found in /lib/kbd/keymaps/i386/
but usually you can use the 2-letter
ISO Country Code. See the ISO website to find the code for the country you require. For example, us
(United States), uk
(United Kingdom), de
(Germany), and no
(Norway).
Setting the system timezone
The system-wide time zone in Linux is defined by the files /etc/sysconfig/clock
and /etc/localtime
.
The file /etc/sysconfig/clock
is used by the system during upgrades to ensure that /etc/localtime
references the latest information. The ZONE
value in /etc/sysconfig/clock
must reference one of the time zone data files in /usr/share/zoneinfo/
. These files contain all the time zone and daylight savings rules for a particular location (for example, /usr/share/zoneinfo/Europe/London
contains all the data for London). These files are part of the base packages installed by the system (they are from the tzdata
package in RHEL and Fedora).
To set the time zone, as the root user, update the value of ZONE in /etc/sysconfig/clock
and run tzdata-update
. You must restart the tideway service to bring the time zone change into effect. For example, to set the time to New York time:
[root@london01 ~]# cp /etc/sysconfig/clock /etc/sysconfig/clock.old [root@london01 ~]# sed -i -e s/ZONE=\"[^\"]*\"/ZONE=\"US\\/Eastern\"/ /etc/sysconfig/clock [root@london01 ~]# tzdata-update [root@london01 ~]# date Thu Oct 29 11:17:27 EDT 2015 [[root@london01 ~]# exit [tideway@london01 ~]$ sudo /sbin/service tideway restart
Setting the system time
You can set the time using the date
command. For example, to set the current date to ten past twelve on 4 July 2013, enter the following command:
[root@london01 ~]$ date -s "12:10:00 20130704" Thu Jul 4 12:10:00 BST 2013 [root@london01 ~]$
The format for the date string is HH:MM:SS YYYYMMDD
.
You can also configure the appliance to synchronize the internal clock to an ntp server. See Configuring the NTP client at the command line for more information.
Do not change the appliance time on to an earlier setting
After BMC Discovery has been running and has created nodes in the datastore, you must not change the system time to an earlier setting. The transaction scheme in the datastore is based on system time time stamps and setting an earlier system time makes data appear out of date causing many transactions to fail.
The system time is not affected by the timezone setting, which is an offset. You can change the timezone without encountering the transaction problems described in this warning.
