32-bit? 64-bit?
swlist -l fileset | grep -i bit
HP
getconf KERNEL_BITS (show 32-bit support)
Also try:
isainfo -v
Is my Operating System 64-bit?
In Solaris, from the command line (you don’t have to be root in most cases) run this command:
/usr/bin/isainfo -kv
If your OS is 64-bit, you will see output like:
64-bit sparcv9 kernel modules
If your OS is 32-bit, you will get this output:
32-bit sparc kernel modules
For Linux users
If you are running Linux, you can check your distribution with the uname command:
uname -m
The output will read x86_64 for 64-bit and i686 or similar for 32-bit.
How about this Oracle install? Is it 64-bit?
The question here is weather your Oracle binaries are 64-bit. While some of the binaries associated with Oracle may be 32-bit, the important ones will be 64 bit. To check those, follow these steps from the command line:
cd $ORACLE_HOME/bin
file oracl*
This will display the file type of your oracle binaries. If you are running 64-bit binaries, the output should look like this:
oracle: ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked, not stripped
oracleO: ELF 64-bit MSB executable SPARCV9 Version 1, dynamically linked, not stripped
If your binaries are 32-bit, the output will look like this:
oracle: ELF 32-bit MSB executable SPARC Version 1, dynamically linked, not stripped
