Determine if 32-bit or 64-bit software is installed on server

Note:
It may be necessary to obtain root priviliges to run the following commands.

AIX

Code:
getconf HARDWARE_BITMODE

This returns the bit mode of the machine hardware, 32-bit or 64-bit.

Code:
getconf KERNEL_BITMODE

This returns the bit mode of the kernel (OS), 32-bit or 64-bit.

HP-UX

Code:
getconf KERNEL_BITS

This returns 64-bit if the operating system is running in 64-bit mode. If it is running in 32-bit mode, then getconf returns an error saying it does not recognize the KERNEL_BITS argument.

EXAMPLES:
On an HP-UX system running in 64-bit mode:

Code:
$ getconf KERNEL_BITS
64

On HP-UX system running in 32-bit mode:

Code:
$ getconf KERNEL_BITS
getconf: Invalid argument (KERNEL_BITS)

Linux

Code:
uname -a

If 'ia64' or 'x86_64' is displayed, the OS was compiled for and is running on a 64-bit processor.

If 'i386' is displayed, the OS was compiled for and is running on a 32-bit processor.

Solaris

Code:
isainfo -v

This command did not exist prior to Solaris 2.7 because by default, they are 32-bit operating systems.

EXAMPLE:

Code:
$ isainfo -v
64-bit sparcv9 applications
32-bit sparc applications

This means the Solaris machine is capable of running 32-bit as well as 64-bit applications.

Windows

Code:
Click on Start > Run. Type 'winmsd' to display the 'System Information' window. 
Look at the 'Item' column for the following entries:

OS Name - If the OS is a 64-bit version, it is listed in the Value column. If not, then it is a 32-bit version by default.

Processor - Find the processor module to determine if the CPU is a 64-bit CPU, such as 'ia64'. This is an Itanium 64-bit CPU.

EXAMPLE:

Code:
For 32 bit: Microsoft Windows XP Professional
For 64 bit: Microsoft Windows XP Professional x64 Edition (5.2, Build 3790)

DBMS

Oracle

To determine the version of Oracle that is installed on a system:

If 64-bit software is running, it is mentioned in the 'connection message'. If not listed, it is a 32-bit base version.

EXAMPLE:

Code:
Connected to:
Oracle8i Enterprise Edition Release 8.1.7.4.0 - 64bit Production.
With the Partitioning option
JServer Release 8.1.7.4.0 - 64bit Production
