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.

`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)

How to Display a System's Logical Processor Type

Use the psrinfo -v command to display information about a system's processor type.
```
$ psrinfo -v
```
On an x86 based system, use the isalist command to display the virtual processor type.
```
$ isalist
```

Example 5-8 SPARC: Displaying a System's Processor Type

This example shows how to display information about a SPARC based system's processor type.

$ psrinfo -v
Status of virtual processor 0 as of: 04/16/2004 10:32:13
  on-line since 03/22/2004 19:18:27.
  The sparcv9 processor operates at 650 MHz,
  and has a sparcv9 floating point processor.

Example 5-9 x86: Displaying a System's Processor Type

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)

Switzerland (German), Switzerland (French) ]

Done.

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)
.
.
.
The Central Europe region (ceu) is installed on this system
