Q. I just want to use suse linux with oracle ,can you tell twins perfomance?
A. SuSE / Novell has developed a package (called orarun.rpm) that does set the user and groups needed to do a basic Oracle (DB) install. it does however ## NOT ## check for the prerequisites.also, orarun.rpm is NOT OFA (Optimal Flexible architerture, Oracle's standard naming convention) compliant :(
i'm usually using the Oracle Installation guide for Linux (manual b15667 for 10.2) as simply follow the instructions (creating home directory, users, groups, rights aso.) AND(!) checking pre-requisites
you don't mention what SuSE (or openSUSE?) you plan to use, but i would recommend:
- SuSE 9 or 10.0 (NOT 10.3) if you plan to use the paying version
- opneSUSE 10.2 if you plan to go with the open source
(open-)SuSE 10.3 are not working smoothly with 10g R2 (or, as far as i could see, 11g) and require a lot of extra work.
actual tuning of the database is up to YOU, dba, following standard Oracle tunning advice once the software is installed and up & running. Novell provides a very good foundation for any software to run smoothly.

Going to school for Computer Information Systems and interested in Security?
Q. I'm currently in the middle of getting my degree at a 2 year community college, my major is Computer Information Systems specializing in IT Support, then transferring to a four year after to continue studies. Iv'e always been interested in Security but unsure of where to start learning about it. A few people have suggested tutorials with Linux Backtrack but I was just curious if anyone could point me in the right direction to learn more about security and working on getting certifications to help stand out when applying for jobs down the road?
A. Hi Alec,
Security is a great area of IT to study. Here is what I would suggest as starting point:
I would first complete the 2 year diploma which you are currently working on before making any significant specializations into IT security. Many people rush into wanting to get on the security side of computing and IT but do not have the basic knowledge to start with. Dependant on what type of security you are looking into I would make sure that you have a thorough understanding of the topics that interest you first.
Then I would start by studying for an IT certification in the Security sector such as the CompTIA Security+ - If you are attending a polytechnic institution then your school may have courses specifically designed to prepare for such certifications. Then you could move onto higher level credentials such as the CEH, CISSP and SSCP. CompTIA certifications are quite common and widely recognized by employers. The CISSP and SSCP are a bit more difficult and require some additional work experience in information security but are very valuable at a later point in time.
My advice to you would be to focus on your university education right now which is invaluable knowledge and provides a well rounded approach. Certifications are great but they do not replace a formal academic education so you are definitely on the right track. I would also take advantage of any security related courses that your school offers. And as mentioned above before you start moving directly into the security side of things I would gain a thorough understanding of the fundamentals such networking, programming the Linux operating system and client/server relationships. Once you have built a strong technical foundation then adding security specialization will not seem like much. Linux and Backtrack tutorials are great, but as mentioned, simply memorizing commands and following tutorials is not as beneficial as actually understanding what you are doing. Security and computer problems in general are presented in so many different ways in the real world so having a the basics down and understanding what is happening first can really help in giving you the ability to tackle any problem that comes your way.
I hope this was able to help and wish you all the best with your studies.
Regards,
Max

Could anybody tell me what's the big difference between linux and windows?
Q. Our office has purchased windows programs with license. Our administrator, however, insist to use linux?
A. Carl P's answer is very good, however there is something which a lot of people don't talk about. Windows evolved from MS-DOS (which itself was a port of CP-M) and conceptually still owes an AWFUL lot to it, even though microcomputers have changed so radically there probably isn't that much code yet.
In fact, we almost never use the term microcomputer for desktops any more. They aren't microcomputers. Microcomputers had a far simpler chip architecture than other computers and Windows had to accommodate this.
MS-Dos evolved on and for independent computers which did not connect with each other by default. These computers were often very simple, and didn't have the resources for forking and other basic things which UNIX used. The first GCC compiler for MS-Dos/Windows came about when D. J. Delorie heard Richard Stallman (who wrote GCC) give a speech where he discussed why he didn't think DOS would ever get a port. Delorie certainly had the right to, but Stallman didn't think it was possible till djgpp proved him wrong.
UNIX, since it was so widely used for networking (the Internet pretty much developed on it and it evolved with it) was and is a modular operating system with programs which work together regardless of what architecture they are compiled for.
As microprocessors started to get sophisticated enough to do things like fork(), Linus Torvalds wrote a kernel of an operating system which would run UNIX programs on the 386 and up microprocessors. Programs like X-Windows, which is what drives Ubuntu desktops and which you will see older versions of on films from Nasa and Carnegie-Mellon as far back as 1987.
There are a lot of profound differences which can be summarized as: Windows is an OS based on MS-DOS which is intended for consumers. Not users, consumers. That's why the hardware demands are so heavy and why Vista was expected to spur hardware sales then didn't. All their design choices are based on that fact and they are so willing to limit your choices that it doesn't provide a very good development environment. It's no wonder your administrator would prefer Linux.
A typical example of what I'm talking about. There was a recent email from Microsoft to the Blender Open Source project -- a three-dimensional animation project which began life as in-house software for an Amsterdam animation house. I don't know what inspired this, other than their efforts to encourage people to develop specifically for windows, but they were trying to get them to do that and talked up two features -- OOXML which has absolutely nothing to do with animation -- and DirectX which is so Windows-specific it makes it hard for programs which render with it to run on MacOS or Solaris or other operating systems.
And that is precisely important. To use two Linux-specific examples, a recent film sponsered by the Blender Foundation (and available for free at http://www.bigbuckbunny.org ) made to show off what the program can do was rendered on a network of Ubuntu boxes. A small, eccentric but neat Linux distro called dyne:bolic (for media activists) has specific documentation for Blender, but instead of talking about animation it discusses setting up networks to render the animations which somebody does.
Ubuntu markets itself as an OS for consumers. What it really is is the UNIX Development Desktop with a Linux kernel and a bunch of scripts and hacks which make it reasonably useful for consumers and the Computer-illiterate. Compare it to a Sun Solaris desktop and you will see what I mean.
Microsoft is a consumer oriented desktop. As such it is focusing more and more on OSes for computers with the latest hardware and unlimited broadband internet connections (since the nineties many of its programs have attempted to access the net with or without the User's permission). That's the bottom line -- there are downsides to Microsoft's approach the company does not discuss at all. And it has made Ubuntu very attractive to a lot of people.
But as an engineer your administrator probably prefers Linux because of the control it gives him over his own machine. Windows Machines, through required patches and validations, are controlled by Redmond. The motto of the free software movement is "free as in freedom, not as in beer."
