How can I tell if Oracle client is 32 or 64-bit?

The fastest way to see if an Oracle Client is 64bit or 32bit, too look for "lib32" and "lib" folders under ORACLE_HOME. If the Oracle Client is 32 bit, it will contain a "lib" folder; but if it is a 64 bit Oracle Client it will have both "lib" and "lib32" folders.

What is the difference between 32 bit and 64-bit Oracle client?

A: No. The 64-bit version simply allows your program to use more memory. There is no real advantage to 64-bit unless you want to fetch a one-billion-row table all into memory on your PC within a Toad data grid.

A simple way to find this out in Windows is to run SQLPlus from your Oracle homes's bin directory and then check Task Manager. If it is a 32-bit version of SQLPlus, you'll see a process on the Processes tab that looks like this:

sqlplus.exe *32 

If it is 64-bit, the process will look like this:

sqlplus.exe

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

Look for <DEP_LIST> on ~second screen.
If following lines have

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

    You may have both 32-bit and 64-bit Oracle Homes installed.
