How to become a good DBA

hi
i am working in oracle from 1 year
on developer and oracle 8i database.
now i am intersting in oracle dba field.
because in INDIA there is a good career of oracle DBA.
so please guide me in DBA filed
1.how we can start learn dba concept.
2.books of oracle dba.
3.interview question related with dba.
4.what are the main concept of dba on that i will work hard.
thanks all.

Some thoughts:
1) You should know datamodelling. This is not specific to Oracle but to a DBA in general. A good DBA knows how to model data! There are several books on datamodelling out there, have a look at any online bookstore. You need this knowledge if you ever want to write good SQL and understand performance impacts and backup & recovery strategies.
2) Read the Oracle concepts documentation. It explains the architecture of Oracle and is the basis of what you need to know when becoming a DBA.
3) As Frederic said: know SQL*Plus! If all else fails, this will allow you to fix things in any circumstance. Certification also revolves around command line interaction.
4) Read the administrator guide. This explains things you need to know for maintaining an Oracle DB.
5) Read a good DBA-tasks book to get an idea of day-to-day things you need to do (the repetitive stuff).
As to what version: it depends on your environment. If you need to work on 8i in your company, start with that. It doesn't make sense to read something you can try out since the version of the database does not allow it. If you have a choise, I would suggest 9i since 8i is old and almost de-supported and phased out soon enough. 10g will come in beginning 2004. Once you have the basic knowledge, it could be handy to at least read the 'new features' documents on the web and keep doing this on a regular basis. They allow you to see differences and how they can be beneficiary to your company/clients. This additional value will be very visible in your company!
I don't agree that you should forget about 10g for the next 3-4 years. It doesn't hurt to keep in contact with the new developments so you know when to use an old version and when a new version. Also, stability is usually not a serious factor. Little cosmetic bugs are fixed fast and shouldn't hamper you in most of your normal DBA work. Besides, within a year you will see companies ask for specific 10g knowledge in their recruitement efforts. So keep your eyes open.
Ask Tom is really good and a must read(!), but not essential in the first weeks of reading. Know sql and Oracle concepts before you read that site, 'cause otherwise it can be confusing at times.

How do i become a better DBA ?

I'm still kind of new the the DBA role and still learning. Well normally I am.
Lately I've not been really busy. All the databases seem to be running OK, there are lots of them, but they aren't in high demand.
So what do i do now ?
What do you recommend I look at or investigate to work towards becoming a better DBA ?
Thanks.

Well, you're already doing a few things right....
You've recognized you have a lot to learn, and you're reading these forums. Those are good things. Also, have a look at the Oracle-L mailing list. (See http:///www.freelists.org and search for 'Oracle-L'.) Look for postings that have questions that interest you. See if you can figure out how to assemble a test case that answers the question. Load Oracle on your home or work laptop or desktop machine, so you have test bed for playing and experimenting. Reading books and documentation is great, but at some point, you have to get hands on, and when that happens, it's good to have a database that you can dsestroy and recreate, with no consequence.
Next, get involved with your local Oracle user group. If you're US based, most major metro areas have a local Oracle user group. If you're based outside the US, it's more likely that you'll find a regional or national level user group. Find out where/when they meet. See what people are working on and/or talking about. Finally, one of the best ways to learn about something, pick a topic, and do a 45-minute or one hour presentation on it at the local OUG. There's really no better way to learn something, than to try to teach it to someone.
Finally, stay interested and curious, for the long haul. Oracle puts out new database releases, each with new features, at an incredible rate. If you're not ready for a lifetime of continual learning, you're in the wrong career. :-)
Hope that helps,
-Mark

What does it take to be a good DBA.

Hi i am a student with 1 year to go and i interested in becoming a DBA i have no real world experience but i have done java ,php,prolog and i have good knowlege of sql queries. I do understand that you need to be good a drivers1,2,3 and 4

Not really. What you need to know and do to be a good DBA is basically be a control freak and totally paranoid about loosing anything... also have an intimate knowlege about backup and recovery and database design. DBA's are paid to ensure the data is there 24X7 365 days a year... yes, every day all day.
If you loose it, don't bother coming back to work.
When the world crashes--and it will--your worth is measured directly by the speed you can recover it all... Yes, all of it, even that stuff that just was updated... oh, the moment the system decided it needed to go south for the winter.
Depending on the shop you are in, you may have other duties--database design, sql queries, programming--helping the developers.
First and foremost you will be the person in charge of making the data secure and accessible to those that need to see it.
Depending on your environment--you may never be allowed to touch Java, php, or prolog. It maybe that you have to subsist on programming in the SQL scripting language or a shop standard.

Thanks1) Get a good java book and read it from start to finish. Understand and then use every technique demonstrated in the book before moving onto the next.
2) Develop good programming practices in general. Use resources like Code Complete and software engineering books to improve the quality of your code and development practices. This is a typical programmer's bookshelf:
[http://www.codinghorror.com/blog/images/my-programming-bookshelf-small.jpg|http://www.codinghorror.com/blog/images/my-programming-bookshelf-small.jpg]
3) Learn new things, always. Start witing things in J2EE. Start writing things in Swing. Even pick up a new language. Different perspectives help you see things in different ways and let you think in new directions.
4) Pay attention to detail. Strive to write the very best code you can every time. Think constantly about how you can do it better.
5) Solicit feedback from peers, coworkers, and quality online communities. Ask them how you can do it better. Post code examples and trust your gut if you suspect that something could be done a better way.
6) Accept that it won't happen overnight. The road to being a "good" programmer is a long one.

- Do an Apps installation yourself (on Linux/Windows)
- Set up users/responsibilities/printers/CM ..etc
- Practice Cloning
- Apply Patches
- Practice AutoConfig to manage system configurations
- Upgrade Database/Application
Go for Oracle Apps training if you can afford it. Moreover, consider to get the following books:
(Oracle Applications DBA Field Guide)

(Installing, Upgrading and Maintaining Oracle E-Business Suite Applications Release 11.5.10+)

How to become a junior DBA?

Hi everyone,
I finished my oracle training program and want to become a junior DBA.
I know 10-month training program is not enough for becoming a junior DBA. SO, could someone please tell me to the way or your story to become a junior DBA?
Thanks in advance for any advice!

nice to hear that u have finished ur course so better to install a oracle old version in your system like 9i or 8i versions Just out of curiosity, why are you recommending he install and practice on versions that are so old they are out of support. Where would he even get them?
and then install a patches the OP would have to have a MetaLink account to get patches. Since he doesn't even have a DBA job, it's extremely doubtful he has access to MetaLink
to ur oracle for updating by doing these you can learn how to update the database it is most important role in DBA and make some tuning to your database without using any tools go through sql optimization method by doing these you can learn all commands very well. then after practicing all these take your database backup and unistall oracle in your system after doing that again install oracle and import that previous backup database by doing these you can learn importing and exporting concepts and also learn RMAN concepts when ever ur attending any interview please go through all these concepts.
better luck for your future.

Is there a way to become a product tester for apple?

So there a way to become or appy for testing iPhones ? I'm a UPS driver and am in a good posstion to put a iPhone thru a vigorous test of everyday life in the working world.

Even if there were, you wouldn't get to Apple through here. We are all users just like you.
And anyway, that kind of testing would likely be done internally within Apple, by Apple employees.

How & where to start with?Do you have any experience programming in any language? If not and you want to start with Java, look up Java Tutorials on google. Or check out java.sun.com for tutorials and examples that are good for beginners. At least learn the basic syntax and structure of the Java language first. From there you can move onto other things like algorithms and design patterns.
Any dress code?How you dress doesn't make you a better or worse programmer. However, if you work for a company you should follow their dress code.

What's the best way to be a good programmer

hi everyone .........
I'm a beginner in Java and I'd like to know the best way to be a good programmer in Java ...
I'll be thankful if u help me and tell me how .

Spend the time to learn the basics of Java first - before you try to write code. A sound understanding of object-oriented principles will allow you to progress much faster than if you blindly start cranking out code without understanding why.
Sun's Java Tutorial is organized so that you learn 00 principles first. It can be pursued either online, or downloaded to your machine, or you can purchase it as a book.

Becoming a Good Editor

Hello, I have just recently graduated with a Bachelor of Arts in Video Production. I want to pursue a career as a video editor, hopefully using FCP. I know the technical aspects of editing, FCP and have even become certified through apple. I don't have much experience since I have just graduated a couple weeks ago. My education has taught me the technical ins and outs of editing, but where I find my weakness is in the esthetics. Anyone can learn the programs, but what makes a good editor? When do you know when to cut? I read the book "In The Blink of an Eye" and was wanting any advise as to where I can learn more about editing, not the technical aspects. Maybe this will just come through experience.
I would appreciate any advice.
Thank you,
Meg

Practice, practice practice... but um...
Here's what I have to suggest (hinted at by others).
DON'T keep yourself in the practice room. You will learn more by surrounding yourself with editors... directors... DPs...
I am in NO way an Editor (capital E), but some of the BEST learning I ever got was by hanging around editors (as a producer) and listening to them talk as they cut the film/video. It is amazing (once you get by the cussing) what they actually say... things like - man, I need a wide shot here (ask why) or aargh, I remember seeing this shot without the boom pole in it - now where was it (why do you KNOW THAT?)... I'm going to cut this riggggghhhhhtttttt HERE (why?)... man, I need to trim three frames off this bugger (why?)
The thought process Murch lays out is nice, but to actually see someone go thru the process INNATELY (or inanely) is priceless.
I am a classically trained musician and conductor... getting past the technique is one of the MOST self rewarding experiences in the human existence. It is also a road of self discovery... and ISN'T taught in schools. Schools crank out film students as much as they do musicians knowing 90% of them shouldn't even be out there, but they do have to justify their budgets.
Just by asking this question and KNOWING that there is more in store for you puts you in that 10%. Now it is up to you to be in the top 10% of them.
Good luck,

Way to become oracle developer

Hi,
I am a MCA garduate interested in oracle development. plz suggest to how to learn oracle step by step to become good oracle developer as I am good in SQl basics.
Regards

Hi,
I can tell you from my experience that if you're genuinely interested in this field, then start applying at places that have entry level positions for people with a desire to learn and grow. Then, on-the-job experience will get you where you want to go. Just think: you will be getting paid to learn (and produce a good working product of course).
As you grow your knowledge and experience, then more opportunities will open up. For your first gig, without experience, it's going to be tough to make a case that you have any kind of specialized knowledge. So start at the entry level and just get your feet wet. There will be plenty of time for on the job learning. Most companies hiring entry level developers are more interested in your aptitude than your experience and/or specific knowledge.

How to become a good ABAPER

Hi Friends ,
i want to become a String and very good ABAPER..
1) how to improve my ABAP SKILLS .
2) First how to analyze the Issue when issue comes from Functional Consultant?
3) how do improve to writting ABAP coding??
pls advice.
Rgeards,
Sreenu

Hi Sreenu,
Let me take a simple example of a report program which displays the sales order data. If the functional consultant gives you an issue which says that the net price appearing in the output is incorrect. I would follow the following steps if given such an issue:
1) Identify which report program is an issue. In other words find which object is giving an issue
2) Understand the issue so that you can narrow your search further. Since the net price is incorrect, I will check the portion of the code where in, the net price (NETWR field in VBAP table) is being populated.
3) If the net price is being populated from the right table, check if it is being manipulated further down in the code.
4) if not, check if this is being changed before the display of the output.
This is only an example and once you get different kind of issues, you will become more used to fixing issues.
Before fixing any code, keep in mind the following:
Will there be any other impacts by fixing the code.
Look at performance considerations
Ensure proper unit testing is done by you and by the functional consultant before the code is transported
Thanks,
Sandeep

Best way to find a good app developer?

My company has an idea for an app that we'd like developed for IP4....
Can anyone here steer us in the right direction insofar as how we find a good app developer who will do contract work?

Where's the best bet to find them? We did contact a few advertising on Monster and some other places, but turns out none of them have been published yet.... Do you know of a good web site or board where we might find a seasoned developer?
Honestly, become an Apple Developer.
http://developer.apple.com/
They have forums where you can ask questions, like "I need an App developer...HELP." Someone will point you to someone. Or volunteer.
Also, LinkedIn has an iPad/iPhone developer group. I belong to a medical apps subgroup, and I can tell you there's a lot of "advertising" of skills and such. Moreover, LinkedIn gives you the chance to do some background checking.
With these two groups, you will get the best of the best. Don't google for one. You'll get junk surrounding the few diamonds.
