I am back ! ! !

It has been a while since my last post here. To be honest, it wasn't lack of time to post. I just got distracted. Anyways, I think I am ready to post some more now. I will try to post at least on a weekly basis.

I added RSS feed functionality to the site so that my readers (no-existent species) can follow up any new posts through their news aggregator of choice.

Ps. In case you are wondering about the picture. Yes, it is an U-turn sign. What does is have to do with anything ? It represents me going back to posting, making a u-turn towards my blog. I know go far with my pictures and posts. But hey, consider it a characteristic of my blog.

First Comment

I got my first comment ! ! ! I am so happy ! ! ! I feel so disvirgined ! ! ! And it was by Mr. Marcio Portes. People are actually reading this stuff.


PS. Pretty cool picture huh ? I got it from here

Transparent Networking Substrat

Does anybody know what TNS (from tnsname.ora) actually stands for ?

It stands for Transparent Networking Substrat. Just a "Did you know ???" kinda question. I love those "Did you know" questions. They are interesting for a sort while, make you think you discovered some extremely important stuff and you never memorize the info on them because it is so useless. :O)
Just though it would be interesting to post TNS here. I have asked experienced people what TNS stood for and they couldn't tell. They were like "All you need to know is that it contains the necessary info to connect to instances of some database".
Now that I know what it stands for, whenever I feel like talking intelligently I will be like:

Some user/developer:

Gleisson Henrique, I can't connect to the database. It says it can't resolve the TNS name. What should I do ? Please help me ! ! ! ! !

Gleisson Henrique:

Well, all you need to do is make sure your Transparent Networking Substrat file is configured properly.

I bet they will be more lost than before talking to me.

PS. Don't I have the stupidest ideas? Look what I wrote three little meaningless letters ! I should be reading my books instead.

Update on status

Just a update on my crusade. I will be honest, I haven't read as much as I would like to. For one reason, I am out of time and secondly I am reading Digital Fortress by Dan Brown which is pretty damn good. Anyways, I am about to start Chapter 5 - Architecture of Beginning Oracle programming. Up to that point, the material was very basic. Really designed for no-prior experience people. Really good book to start off with.

My tools

In order to achieve my goals, I will use a couple of tools to me help me out. Here they are:

1. This blog.
   

I would post comments, updates, progress, new things I am learning, how something makes sense now.

2. My books.

The books I have in the picture are not my only ones. I have 22 books and counting on Oracle Technology (Database, PL/SQL, and Forms) and a set of 4 books for 9i certification. So not even half of my books made to the picture above. Most of them I own for about an year now and never touched. That's very sad and disappointed. But hey, now is not the time to be sorry. I am taking action on it. I will start with very basic chicken soup kind of book and then move on to more in depth concepts of the technology. The ones that made the picture are the ones I will read in the following order:

I hope by the time I am finished with them, I will be a proficient programmer with DBA knowledge.

3. AskTom

Great forum for questions and answer by someone no other that Mr. Tom Kyte.

4. OTN

If there's one thing that simply rocks about Oracle is the network of support, forums, documentation, how-to's and etc that the company has put together.

5. "Links I am addicted to" section in my blog.

Just a very small list of blogs I read about people with experience talking about technology.

6. Steven Feuerstein

Great programmer, great citizen, great activist. You can find him here, here, here.

7. The Tom Kyte blog

Tom Kyte is just out of this word. I read his blog religiously.

8. Google

Great little search engine you might have heard about.

9. Online communities and support.

Orafaq, my oracle related communities at orkut , Oracle-l.

10. And a bunch of other sources.

There are blogs I didn't mention such as The Dizwell, Mark Rittman and others that I didn't mention here.

11. Your replies.

Of course my visitor's replies (if I have any).


My only fear is that I get lost in middle of the road. I will have to do a lot of reading, but it isn't just reading is understanding and putting into practice and building up good ethics and practices.

Hopefully, I will be successful with my little project. If not, at least I read a lot of good books.

To Learn Oracle

I have decided that I will learn Oracle in depth. So long "I think this works like this" or "I would just google for xyz syntax or best way to do something" or "I better not touch 'cause it's working fine". It will be a long way I know. Knowledge is a never ending quest, but enough is enough. I have been in the Oracle world for a little over two years now. Much of what I know is basic, note that I have a tendency to discredit myself a lot, I want to be the guy everybody turns to when something happens. I am that guy right now at job, but not for the right reason. I am the only one in my IT Division. Don't get me wrong I have never turned down an user's request because I didn't know what to do. I guess my developer side is pretty good and have, always, helped me a lot.

It just seems logical. I have everything in my favor. My job is not really high demanding I can easily take two hours to study everyday. I own about 15 books on Oracle and PL/SQL Programing. Heck, I even have the study program to certification and never even cut the wrapping plastic. So what the hell is wrong with me ? Or why did it take so long ? Lack of good tutoring and dedication. A tutor, a mentor is everything. Somebody experienced that you can turn to is essential in every area. My tutor has been Google . And dedication ? Well that's just all on me. I have planed to do this earlier a couple times before but I gave up. It was too much. I never though I would be able to detain so much knowledge and information. But now I won't give up this time. I will read, study, and analyze every little piece of info I can get my hands on.

So watch out Tom Kyte pretty soon I will post questions for you at AskTom .

Blogging here I am.

Pretty new to all this blog stuff. I am not much of a reader nor of a writer. So I don't think I can really put a paragraph together that will start, develop and then finish a thought. But hey my english professor says that blogging is good to improve writing .

A lot of stuff came to my mind before I put my first post, the blog is up for almost a year now just so I could say I had a blog like everybody else did. First, what to blog ? I wanted to do something that I could share but at same time would be interesting to people. But what could I do ? I still don't know. I will post whatever I fell like, mostly of the posts will be about Oracle and PL/SQL and all the boring stuff about programming.

Second thing came to mind was whether to post in english or portuguese. I am from Brazil and moved to the US in 99. Since I intend to post mainly about programming I will post mostly in english. One thing I learned is whatever I learned in English I really don't know how to say in Portuguese. For example, I entered the Oracle world after I moved to the US, so most of the stuff I know about Oracle is in english and I can't really think of a way to say it in portuguese. For example, triggers ! In english it makes perfect sense to say that an event triggered the database. How about in portuguese? Um evento engatilhou o banco de dados or Um envento disparou o banco de dados. It just sound funny and like bad portuguese to me. Plus coding in english makes easier to read the code. The keywords are in english and your variables are in english just makes more sense when you are reading the code. But anyways I will throw some portuguese from time to time and hopefully I will learn all the technical lingo in portuguese someday.

In summary that's it ! hopefully I somebody will read my blog ! Please, please, please read me people !!!!!
