Oracle Pre Built VMs for Database Development 32-bit or 64-bit
The Oracle pre-built VMs for database development are a great productivity booster. You can download them and immediately start development being assured that the entire stack is installed correctly and working.
Here's how you can check to see whether or not you have a 32-bit or 64-bit installation.
cat /proc/version file /sbin/init
you should see output similar to this for 32 bit
[oracle@localhost ~]$ file /sbin/init /sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped [oracle@localhost ~]$ [oracle@localhost ~]$ cat /proc/version Linux version 2.6.18-126.96.36.199.1.el5 (firstname.lastname@example.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Wed Sep 29 15:40:03 EDT 2010 [oracle@localhost ~]$
Hope this helps, George
