How to Determine Whether a System Has 32–bit or 64–Bit Solaris Capabilities Enabled
- Use the isainfo command to determine whether a system has 32–bit or 64-bit
capabilities enabled.
# isainfo options
The isainfo command, run without specifying any options, displays the name or names
of the native instruction sets for applications supported by the current
OS version.
- -v
Prints detailed information about the other options
- -b
Prints the number of bits in the address space of the native instruction set.
- -n
Prints the name of the native instruction set used by portable applications supported by the current version of the OS.
- -k
Prints the name of the instruction set or sets that are used by the OS kernel components such as device drivers and STREAMS modules.
Note - For x86 based systems, the isalist command can also be used to display
this information.
For more information, see theisalist(1) man page.
Example 5-1 SPARC: Determining Whether a System Has 32–Bit or 64–Bit Solaris Capabilities Enabled
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 applications
This 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 applications
This 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
32
The isainfo command output from a 64–bit UltraSPARC system that is running the
64–bit Solaris Operating System is displayed as follows:
$ isainfo -b
64
The 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.
Example 5-2 x86: Determining Whether a System Has 32–Bit or 64–Bit Solaris Capabilities Enabled
The isainfo command output for an x86 based system that is running the
64-bit kernel is displayed as follows:
$ isainfo
amd64 i386
This 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
32
The isainfo command output from an x86 based system that is running the
64–bit Solaris Operating System is displayed as follows:
$ isainfo -b
64
You 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 i86
In the preceding example, amd64 indicates that the system has 64–bit Solaris capabilities
enabled.
How to Display Solaris Release Information
How to Display General System Information
- To display general system information, use the showrev command.
$ showrev options
- -a

openprom version: 'OBP 3.15.2 1998/11/10 10:35'
How to Display a System's Installed Memory
- To display the amount of memory that is installed on your system, use
the prtconf command.
Example 5-6 Displaying a System's Installed Memory
The following example shows sample output from the prtconf command. The grep Memory command
selects output from the prtconf command to display memory information only.
# prtconf | grep Memory
Memory size: 128 Megabytes
How to Display the Date and Time
- To display the current date and time according to your system clock, use
the date command.

psrinfo Command Option to Identify Chip Multithreading Features
Solaris 10: The psrinfo command has been modified to provide information about physical processors,
in addition to information about virtual processors. This enhanced functionality has been added to
identify chip multithreading (CMT) features. The new -p option reports the total number
of physical processors that are in a system. Using the psrinfo -pv command
will list all the physical processors that are in the system, as well
as the virtual processors that are associated with each physical processor. The default
output of the psrinfo command continues to display the virtual processor information for
a system.
For more information, see the psrinfo(1M) man page.
For information about the procedures associated with this feature, see How to Display a System's Physical Processor Type.
How to Display a System's Physical Processor Type
- Use the psrinfo -p command to display the total number of physical processors on
a system.
$ psrinfo -p
1
Use the psrinfo -pv command to display information about each physical processor on
a system, and the virtual processor associated with each physical processor.
$ psrinfo -pv
The UltraSPARC-IV physical processor has 2 virtual processors (8, 520)
The UltraSPARC-IV physical processor has 2 virtual processors (9, 521)
The UltraSPARC-IV physical processor has 2 virtual processors (10, 522)
The UltraSPARC-IV physical processor has 2 virtual processors (11, 523)
The UltraSPARC-III+ physical processor has 1 virtual processor (16)
The UltraSPARC-III+ physical processor has 1 virtual processor (17)
The UltraSPARC-III+ physical processor has 1 virtual processor (18)
The UltraSPARC-III+ physical processor has 1 virtual processor (19)
When you use the psrinfo -pv command on an x86 based system, the
following output is displayed:
$ psrinfo -pv
The i386 physical processor has 2 virtual processors (0, 2)
The i386 physical processor has 2 virtual processors (1, 3)

This example shows how to display information about an x86 based system's processor
type.
$ isalist
pentium_pro+mmx pentium_pro pentium+mmx pentium i486 i386 i86
New localeadm Command
Solaris 10: The new localeadm command allows you to change the locales on your
system without reinstalling the OS or manually adding and removing packages. This command
also allows you to query your system to determine which locales are installed.
To run the localeadm command, you must have superuser privileges or assume
an equivalent role through role-based access control (RBAC).
For more information, see the localeadm(1M) man page.
For more information in this guide, see Chapter 5, Displaying and Changing System Information (Tasks).
How to Display Locales Installed on a System
- Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
- Display the locales currently installed on your system using the localeadm command.
The -l option displays the locales that are installed on the system. For
example:
# localeadm -l
Checking for installed pkgs. This could take a while.
Checking for Australasia region (aua)

How to Determine if a Locale is Installed on a System
- Become superuser or assume an equivalent role.
Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.
- Determine if a locale is installed on your system using the localeadm
command. 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)
.
