Listers,
Here is a little summary of commands to identify the bit version of an o/s and 2 methods of identifying whether a database is a 32 bit or 64 bit installation

Operating System

Compaq Tru 64 - will be 64 bit

HP-UX  	/usr/sbin/swlist | grep -E '32|64' returns 
	HPUXEng64RT           B.11.00.01     English HP-UX 64-bit Runtime
Environment if 64 bit
Sun 		isalist -v

If the return contains the phrase 'sparcv9' then it is a 64 bit o/s Oracle Version
To check Oracle version - 2 methods
do a file on $ORACLEHOME/bin/oracle returns either ELF-32 or ELF-64 executable
Within sqlplus desc v$session and look for the definition of saddr (if raw(4) then 32 bit else if raw(8) 64 bit)
