For x86 based systems, the isalist command can also be used to display this information.For more information, see theisalist1 man page. The isainfo command output for an UltraSPARC system that is running previous releases of the Solaris OS using a 32-bit kernel is displayed as follows:$ isainfo -v 32-bit sparc applicationsThis output means that this system can support only 32–bit applications.The current release of the Solaris OS only ships a 64–bit kernel on SPARC based systems. The isainfo command output for an UltraSPARC system that is running a 64–bit kernel is displayed as follows: $ isainfo -v 64-bit sparcv9 applications 32-bit sparc applicationsThis output means that this system is capable of supporting both 32–bit and 64–bit applications. Use the isainfo -b command to display the number of bits supported by native applications on the running system.The output from a SPARC based, x86 based, or UltraSPARC system that is running the 32–bit Solaris Operating System is displayed as follows: $ isainfo -b 32The isainfo command output from a 64–bit UltraSPARC system that is running the 64–bit Solaris Operating System is displayed as follows:$ isainfo -b 64The command returns 64 only. Even though a 64–bit UltraSPARC system can run both types of applications, 64–bit applications are the best kind of applications to run on a 64–bit system. The isainfo command output for an x86 based system that is running the 64-bit kernel is displayed as follows:$ isainfo amd64 i386This output means that this system can support 64–bit applications.Use the isainfo v command to determine if an x86 based system is capable of running a 32–bit kernel.$ isainfo -v 64-bit amd64 applications fpu tsc cx8 cmov mmx ammx a3dnow a3dnowx fxsr sse sse2 32-bit i386 applications fpu tsc cx8 cmov mmx ammx a3dnow a3dnowx fxsr sse sse2 This output means that this system can support both 64–bit and 32–bit applications.Use the isainfo -b command to display the number of bits supported by native applications on the running system.The output from an x86 based system that is running the 32–bit Solaris Operating System is displayed as follows: $ isainfo -b 32The isainfo command output from an x86 based system that is running the 64–bit Solaris Operating System is displayed as follows:$ isainfo -b 64You can also use the isalist command to determine whether an x86 based system is running in 32–bit or 64–bit mode.$ isalist amd64 pentium_pro+mmx pentium_pro pentium+mmx pentium i486 i386 i86In the preceding example, amd64 indicates that the system has 64–bit Solaris capabilities enabled.

The q option and a locale queries the system to see if that locale is installed on the system. To see if the Central European region (ceu) is installed on your system, for example:# localeadm -q ceu locale/region name is ceu Checking for Central Europe region (ceu) . . . The Central Europe region (ceu) is installed on this system Task Directions For Instructions Manually set a system's date and time. Manually set your system's date and time by using the date mmddHHMM[[cc]yy] command-line syntax. How to Set a System's Date and Time Manually Set up a message-of-the-day. Set up a message-of-the-day on your system by editing the /etc/motd file. How to Set Up a Message-Of-The-Day Change a system's host name. Change your system's host name by editing the following files:/etc/nodename /etc/hostname.*host-name /etc/inet/hosts If you are running the Solaris 3/05, 1/06, 6/06, or 11/06 releases, you also need to update the /etc/inet/ipnodes file. Starting with Solaris 10 8/07 release, the Solaris OS does not have two separate hosts files. The /etc/inet/hosts file is the single hosts file that contains both IPv4 and IPv6 entries. How to Change a System's Host Name Add a locale to a system. Use the localeadm command to add a locale to your system. How to Add a Locale to a System Remove a locale from a system. Use the r option of the localeadm command and the locale to remove of locale from your system. How to Remove a Locale From a System This section describes commands that enable you to change general system information.&rolestep.sgm;Enter the new date and time. # date mmddHHMM[[cc]yy]mmMonth, using two digits. ddDay of the month, using two digits. HHHour, using two digits and a 24-hour clock. MMMinutes, using two digits. ccCentury, using two digits. yyYear, using two digits. See the date1 man page for more information. Verify that you have reset your system's date correctly by using the date command with no options. The following example shows how to use the date command to manually set a system's date and time. # date Wed Mar 3 14:04:19 MST 2004 # date 0121173404 Thu Jan 21 17:34:34 MST 2004 Edit the message-of-the-day file, /etc/motd, to include announcements or inquiries to all users of a system when they log in. Use this feature sparingly, and edit this file regularly to remove obsolete messages. &rolestep.sgm;Edit the /etc/motd file and add a message of your choice.Edit the text to include the message that will be displayed during user login. Include spaces, tabs, and carriage returns. Verify the changes by displaying the contents of the /etc/motd file.$ cat /etc/motd Welcome to the UNIX Universe. Have a nice day. The default message-of-the-day, which is provided when you install Solaris software, contains SunOS version information. $ cat /etc/motd Sun Microsystems Inc. SunOS 5.10 Generic May 2004The following example shows an edited /etc/motd file that provides information about system availability to each user who logs in. $ cat /etc/motd The system will be down from 7:00 a.m to 2:00 p.m. on Saturday, July 7, for upgrades and maintenance. Do not try to access the system during those hours. Thank you. A system's host name is specified in several different locations.Remember to update your name service database to reflect the new host name.Use the following procedure to change or rename a system's host name.You can also use the sys-unconfig command to reconfigure a system, including the host name. For more information, see the sys-unconfig1M man page. &rolestep.sgm;Change the system's host name in the following files:/etc/nodename /etc/hostname.*interface /etc/inet/hosts /etc/inet/ipnodes – Applies only to some release Solaris releases. Starting with the Solaris 10 8/07 release, there is no longer two separate hosts files. The /etc/inet/hosts file is the single hosts file that contains both IPv4 and IPv6 entries. You do not need to maintain IPv4 entries in two hosts files that always require synchronization. For backward compatibility, the /etc/inet/ipnodes file is replaced with a symbolic link of the same name to the /etc/inet/hosts file. For more information, see the hosts4 man page. If you are using a name service, change the system's host name in the hosts file. Rename the host name directory within the /var/crash directory.# cd /var/crash # mv old-host-name new-host-name Reboot the system to activate the new host name.# init 6 &rolestep.sgm;Add the packages for the locale you want to install on your system using the localeadm command.
