Check Oracle Client/Windows running on 64 Or 32 Bit

April 4, 2012

How to find if  Windows OS and Oracle client is 32 Bit or 64 Bit version ?

(A) How to know installed Windows bit version

1) Using cmd.exe OR command prompt

C:\> set processor_arc (throws one of the following outputs)

C:\Documents and Settings\e518138\Desktop>set processor_arc

Result Interpret from above output:

PROCESSOR_ARCHITECTURE=x86 (this means – you’re using 32-bit Windows )
PROCESSOR_ARCHITECTURE=AMD64 (this means – you’re using 64-bit Windows )
PROCESSOR_ARCHITEW6432=AMD64 (this means – you’re running a 32-bit cmd interpreter on 64-bit Windows )

2) Alternatively the bit version could be know via below
This information is also available  via  msinfo32 or sysinfo32 command.

Start=> Run => TYPE msinfo32

3) Following command helps find OS bit version and can be redirected to file.

REG.exe Query HKLM\Hardware\Description\System\CentralProcessor\o   => Here ( o is Numeric 0)
C:\Documents and Settings\e518138\Desktop> REG.exe Query HKLM\Hardware\Description\System\CentralProcessor\o


Component Information       REG_BINARY      00000000000000000000000001000000
Identifier  REG_SZ  x86 Family 6 Model 15 Stepping 11
Configuration Data  REG_NONE        FFFFFFFFFFFFFFFF0000000000000000
ProcessorNameString REG_SZ  Intel(R) Core(TM)2 Duo CPU     E6550  @ 2.33GHz
VendorIdentifier    REG_SZ  GenuineIntel
FeatureSet  REG_DWORD       0xa0033fff
~MHz        REG_DWORD       0x917

Previous Update Signature   REG_BINARY      00000000B6000000
Platform ID REG_DWORD       0x1

Result Interpret from above output:
if query returns “x86 Family 6” windows is 32-bit.
if query returns “Intel 64 Family 6” windows is 64-bit.

(B) How to know installed Oracle Client bit version on Windows.

(A) From command Prompt :
C:\Documents and Settings\e518138\Desktop> hostname

C:\Documents and Settings\e518138\Desktop> tnsping

TNS Ping Utility for 64-bit Windows: Version – Production on 27-MAR-2012 06:52:39

TNS-03502: Insufficient arguments.  Usage:  tnsping <address> [<count>]

 (B) Oracle Inventory Logs in Program files :
On 32-bit windows : Only one folder C:\Program Files

On 64 bit windows : There are two folders with Program files :
(a) C:\Program Files             (if any 64 bit apllication is installed their information goes here)
(b) C:\Program Files(x86) (if any 32 bit apllication is installed their information goes here)

Go to Folder C:\Program Files\Oracle\Inventory\logs\ and look for file => installActionsYYYY-MM-DD_HH-MI-SSPM

Open the file and search for value “64-bit”
