For Remote DB access : Can i remove 127.0.0.1 this default ip from /etc/hosts ?


Good Morning to all ;

I need some information about n/w connectivity. Really i am getting much confusions so i am preparing to submit new document to my Juniors.

Every time i am saying "Oracle DBA Team".

Even i ask my co workers (unix team) few things are not understandable so i am coming here.

From vi /etc/hosts/

127.0.0.1

Quote:
IP ADDRESS 127.0.0.1 always mean "This machine on which I am sitting". So, all computers are known as "localhost" or 127.0.0.1". - No remote client can ever connect to DB Server using 127.0.0.1
QUES 1 :

For Remote DB access : Can i remove 127.0.0.1 this default ip ?

QUES 2 :

My ip and domain_name , machine_name configured here , what is the need to update neat file ?

Note : I won't update anything in taht file. Just i am going to submit env doc for my team. That's it !!

Thanks in advance ..

Right...and every time we are saying "if you aren't a Linux administrator, why are you trying to train others in Linux?"

And again, if you can't talk to your co-workers, you have serious issues at your workplace that you should take to your superiors.

No, never, for any reason. This is well documented and explained in the documentation you have been sent BEFORE, in some of your other threads.

No idea what you mean by a 'neat' file. There are utilities that are Red Hat/Fedora specific that start with 'neat', but they are just front-ends for editing network configurations. Again, read the documentation you've been pointed to before about configuring network on Red Hat.

Again, if you're writing training documentation for your team (and your team is comprised of ORACLE administrators), then why don't you write the Oracle pieces, and give the document to the Linux administrators for their input? That would ensure it's accurate, and that your 'juniors' will get correct information.

The Red Hat documentation about /etc/hosts that you've been sent before is just ONE PAGE of a larger document. Try reading those other pages, or searching Red Hat's knowledgebase.

Please TBone. I am not focusing Entire Linux. I want to know minimum things (efficiently to work with oracle).

Hmm.. If you wish , please Hit here .. because some concepts are necessary to know about LINUX and training to my Oracle Juniors.

http://www.scribd.com/doc/121116319/...ssion-in-Linux
http://www.scribd.com/doc/121119776/...ssion-in-Linux

- Above mentioned links are some sample docs to my juniors.

Hmm .. I am interacting with unix team as well as i can't ask (UNIX TEAM) to teach LINUX concepts. Here also i'm n't asking to teach linux. (JUST i'm asking to clarify some basic doubts) Here This is good place and I can interact with experts (LINUX GURUS).


Why i am teaching linux concepts to Oracle folks

Everyone should know about our work - That's it. I'm also not expert in oracle or linux. but learning ..


Quote:

Yes , but what about LINUX concepts (How can i solve knowledge gap in linux )

TBONE :Again i'm saying only one point( I can't ask tutting linux concepts with unix team and always i am interacting with unix team)

# neat comamnd in linux : what is the need to update neat file about my domain name , ip address?

Thanks TBone[GURU] ..

Preparing documents to my juniors is my Important Work .. I should do that (even linux with Oracle).

Ok...then you really should start by reading the Oracle documentation, on how to install it on Linux, and configure a Linux system to run Oracle, shouldn't you? Those documents are already available with Oracle, and if you want to drill down into those concepts more (like how to make a directory or edit a file), then use that as a base and expand on it. But the things you're asking are not really relevant to installing/configuring Oracle, and have also been answered several times already.

No thanks.

And AGAIN...WHY is asking a team of people who know these things a bad idea, especially if you WORK WITH THEM, and you're doing ON THE JOB TRAINING??? And aren't the people you work with, at your company, 'Linux Gurus'??? If you can't talk to your co-workers, you have serious issues at your workplace that you need to address.

You start by looking things up, and reading what's given to you. You asked for information, but only seem to read one page of it.
Quote:

And again I'm asking WHY YOU CAN'T TALK TO YOUR CO-WORKERS???? They are the Linux Team, who work at the SAME COMPANY AS YOU DO. Asking a question should be trivial. Your response is "I can't ask them, because they're the Linux team, and I always interact with them", makes no sense whatsoever. Asking your co-workers who work with Linux every day a question about Linux (that is also WORK RELATED), would be the most logical thing to do.

And AGAIN, you don't seem to read/understand what folks are asking you. I said "No idea what a neat file is"....and you still haven't said what it is. What 'neat file" are you talking about? Where? Name? The file with that information in it, is /etc/hosts, and you've been given examples of it a few times now. AGAIN...read the documentation you've been given (several times). Your domain name and other information can also come from DNS, but again, reading the Red Hat documentation is a good start...and AGAIN....you can go to the Red Hat knowledegbase, since you're paying for access to it, and read all of this easily.

Right...which is why it's essential that you give them CORRECT, ACCURATE INFORMATION. Which is why you need to talk with your co-workers....read/understand documentation, and learn how to look things up on your own.
