Does anyone know Oracle e-Delivery (link below)? It looks like free download of linux is available form this site.

Question:
1. What is the difference between Oracle Linux x86 32 bit and x86 64 bit?
2. How can I verify which one (x86 32 bit vs. x86 64 bit) I need for my PC?
3. What's the difference between the two below (one with Source and the other without 'Source')? I am trying to figure out which one I need.
- Oracle Linux Release 5 Update 2 for x86_64 (64 Bit)
- Oracle Linux Release 5 Update 2 Source for x86_64 (64 Bit)

1. means what it says; in very short terms 64 bit OS can address much larger amts of RAM natively, can be useful for eg Oracle DB
http://www.redhat.com/rhel/compare/

2. http://www.cyberciti.biz/faq/linux-h...64-bit-or-not/ note that if you have a 64bit processor, you can run 32 bit OS if you want (although you prob wouldn't).
Note also that as Oracle Linux is a copy of RHEL, 64 bit will be multilib, meaning a 64bit OS+kernel can still run 32bit SW if you don't have the 64 bit available.

3. without src means what it says, you just get the binaries, which is normally all you need.
The src is for if you want to re-compile/customise the SW yourself. Very unlikely if you are asking this qn

4. bonus answer: As above, OEL is based on RHEL, which is currently on 5.6 for v5.x and 6.1 for 6.x series.
See http://www.linuxtopia.org/online_boo...ion_index.html for the relevant manuals

Stop! and I mean that in a nice way.

You need to start with live cd's instead of that. Your questions show me that you will just bork your system.

To make your live easier I believe they offer that in a pre-made virtual machine download. The next newbie step up from live cd's is maybe virtual machines.

Thank you, both for replying.
