Find database bit version (64bit, 32bit)

There are several ways to determine that.  But let’s discuss just one version for Linux, one for Windows and one for Database.  🙂

If OS is Linux you can check it by file command.

 file $ORACLE_HOME/bin/oracle

/u01/app/oracle/product/12.1.0.2/dbhome_1/bin/oracle: setuid setgid ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, not stripped

So my oracle is 64bit.

If it is windows:

Go to %ORACLE_HOME%\inventory\ContentsXML folder and open comps.xml file

Look for <DEP_LIST>
If following lines have

• PLAT="NT_AMD64" then this Oracle Home is 64 bit.
• PLAT="NT_X86" then – 32 bit.

The above commands was from OSs itself. You can get this information from database also.

select metadata
from sys.kopm$ ;

0000006001240F050B0C030C0C0504050D0609070805050505050F0
5050505050A050505050504050607080823472347081123081141B047…

If you see B047 then software is 64bit and if there is B023 then 32bit.
