Solaris 32-bit 64-bit for Oracle

Oracle Database Tips by Donald BurlesonJanuary 23, 2015

Question How can I tell of my Solaris system is 32 bit or 64 bit? Also, can I run a 32-bit Solaris application on a Solaris 64-bit ystem? Is there a command to tell if I am 32-bit or 64-bit Solaris?

Answer: Yes, you can run a 32-bit Solaris application on a 64-bit OS, but not conversely.

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
