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.

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 to become an apps DBA

Hi,
I have been an DBA for almost 4 years and right now, I will like to move towards administrating Oracle 11i server.
Can anyone out there recommend me on how should I move towards that direction?
Kindly please advise me.
thanks
Kenny

I would say that without question the best training is doing. A rather basic two-tier linux system from Dell for your own testing can host an 11i Vision Demo. Practice the installation a couple of times and then start on patching basics - adpatch type patches, Forms6i type patches, database patches. Come up with a good backup and recovery strategy and do some crazy things like apply major rollup patches and skip a prereq just to see what happens. Then try and troubleshoot why it failed. Of course, this all within your own personal Vision Demo instance where you have total freedom to break things. No one would do this a "real system". :-)
Once you've mastered patching basics, expand out into the advanced topologies and setup a DMZ such as in Note:287176.1. Set up a RAC, setup parallel concurrent processing, go nuts!

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

Junior dba please help

hello,
our production server is DEDICATED SERVER,upto last month max sessions for
the server is 50 -60 ,but now sessions are increased to 170 - 180.So due that
server performance become very slow,So we wan't to change from DEDICATED
SERVER to SHARED SERVER.For this as a junior DBA i wan't help from u.
as far as i know when we change the server from DEDICATED
SERVER to SHARED SERVER the following parameters will be used
DISPATCHERS:
SHARED SERVERS
i wan't to know how many DISPATCHERS and SHARED SERVERS
i have to create,and how many
As far as i know of connections exceed more than 1000 then no of dispatchers =2
but for ur server max no of connections opening are 200.And for every 10 connections one SHARED SERVER.Is this estimation correct or not
please help
regards

I suggest you to use a more meaningful title for your thread.
Next, just for the fact your database has become slower and the number of users increased doesn't mean that setting shared servers will be the solution, it could be but i couldn't as well, unless of course, you have determined you have run into a memory shortage and you are already running on virtual memory.
Your system will benefit from shared servers only if its activity is mainly oriented to OLTP, if you have DSS operation (FTS, sorts, analytic queries and batches) it will produce the opposite effect and no performance gain will be noticed.
As far as i know of connections exceed more than 1000 then no of dispatchers =2
but for ur server max no of connections opening are 200.And for every 10 connections >one SHARED SERVER.Is this estimation correct or notIf you are certain Shared Server is the solution for your performance loss, the above criteria is just an empirical a priori estimation, you have to set according to your load and monitor, leave a wider shared server and dispatchers growth margin and monitor using V$SHARED_SERVER, V$DISPATCHER, and V$CIRCUIT dynamic views.

- 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:

How to become Mentor & Moderator?

Dear Friends,
I was just tracking the earlier post regarding how to become a Moderator, but there seem no definite answers...
Can someone please tell me answers to following:
1. How to become a Mentor in any one of SDN Forum?
2. How to become a Moderator in any one of the SDN Forum?
Thanks,
Jignesh Mehta

> My observation says, Mentor and moderator are opposite roles. Mentors should have more patience to encourage members participation. They never recommend the members to search forum even for a basic question. Moderators should not have soft corner and if somebody violates the rules of engagement of this forum, they move the threads to other forums, lock the threads, guestify the members. If any thread is found inappropriate, they will move it to coffee corner by default.
I disagree with you on this from both angles.
First, although not a SCN Mentor, I mentor and have mentored many juniors/freshers. It's a sometimes frustrating, but mainly rewarding task, that I'm glad to undertake. As a mentor though, I have zero patience for people who won't try to help themselves and expect answers to be spoonfed. I want those under my guidance to learn how to fish - not just give them a fish.
So mentoring involves not just helping with the specifics, but also guiding people in the techniques for solving problems themselves.
Now, moderating isn't all about enforcement - it's also about education.
With regards to easily searched, basic questions, if the person has clearly tried and still not got it, then I'll gladly help. But questions like "how do I convert dd/mm/yyyy to yyyymmdd", "how do I send external email from SAP", "how do I download a table to my PC" - these Frequently Asked Questions - no-one, never mind mentors should be responding. They should be reported to the moderators.
Now, with newbies, I, at least, strive to be gentle, by for example, sending them an email asking them to read the Rules of Engagement, and to try to search first. I even suggest what keywords to use. But if they've a few hundred posts, then they'll get a stern rejection. Even then, some people just don't pay attention. sigh On the other hand, some people manage to get a stay of execution by showing, and proving, a desire to change. One of our best contributors came very close to guestification in the early days, but "heaven has more joy over one sinner who repents...!".
My goal as a moderator is to keep the forums clean and useful. Not just as a place to ask questions and get answers, but also a searchable resource. Otherwise, we might as well just delete all questions older than a month!

How to become a java master-hand?

Excerpt from: The Touch of the Master's Hand by Myra Brooks Welch
"A thousand dollars, and who'll make it two?
Two thousand! And who'll make it three?
Three thousand, once; three thousand, twice;
and going, and gone!" said he.
The people cheered, but some of them cried,
"We do not quite understand
What changed its worth?" Swift came the reply:
"The touch of the masters hand."
But the Master comes, and the foolish crowd
never can quite understand
The worth of a soul, and the change that's wrought
by the touch of the Master's hand.

Hi,
Read all what is available about SOA on SDN. This is the best to do now.

How to become microft community contributor or MVP

Hi,
How can i achieve MCC / MVP award. :-)
Cheers, Hemendra-MCTS "Yesterday is just a memory,Tomorrow we may never see"

Thanks for asking this question! Everybody also wants to know this!
Sometimes answers aren't what we want them to be. The process might not be as detailed as we want, but that's by design (for flexibility and other reasons). Since this forum is to discuss recognition, the recognition aspect is as follows: When
you become an MCC or MVP, then you receive the appropriate "MCC" or "MVP" mark.
To find out how to become an MCC or MVP, we should go check out their sites and ask them. The "MCC" and "MVP" marks on here only reflect that the award was given... and the Recognition Points might inform the award. But the award itself has nothing
to do with the Recognition system or the forums. So here's the answer and links for you to find out more information if you want it...
MICROSOFT COMMUNITY CONTRIBUTOR (MCC)
Q14. How do I contact Microsoft about the Community Contributor Award?
A14. You can send questions to the Microsoft Community Contributor Global Administrator at
[email protected] (MCCGA at microsoft.com).
FAQ:
https://www.microsoftcommunitycontributor.com/faq.aspx
PROCESS: Current MVPs and Microsoft personnel recommend people as MCCs based on quality, quantity, and impact on "online technical communities." Current MVPs and Microsoft personnel then evaluate those recommended on the same factors (impact on
online technical communities) and base the award on those evaluations. If you think they should be more transparent about the process, let them know with the links above.
Tips to becoming an MCC (based on the FAQ):
1) Make an impact in the community, using tools like TechNet Forums, Gallery, and Wiki.
2) Become noticed by MVPs and Microsoft's MCC representatives (start building relationships with these folks and collaborating).
MOST VALUALBE PROFESSIONALS (MVP):
Become an MVP:
http://mvp.support.microsoft.com/gp/mvpbecoming (if it doesn't open, paste into a new tab or window)
Nominate an MVP:
http://mvp.support.microsoft.com/gp/mvpnominate (if it doesn't open, paste it into a new tab or window)
Process: After reading the "become an MVP" page, you'll see that the process is rigorous. "MVP nominees undergo a rigorous review process. A panel that includes members of the MVP team and Microsoft product groups evaluates each nominee's technical expertise
and voluntary community contributions for the past 12 months. The panel considers the quality, quantity, and level of impact of the MVP nominee's contributions." Essentially the panel evaluates the nominees and then bases their award on those evaluations in
quality, quantity, and level of impact.
Tips to becoming an MVP (based on the MVP site):
1) Give quality assistance, advice, processes, scripts, and consultation. Test your own advice and ask first. Experts in your area will be evaluating samples of your community work. You don't want them to be evaluating the one communication issue you had
or mistake you accidentally made (and thus thinking that you make it a regular practice).
2) Give high-quantity contributions. Be active in your technology's forums and on blogs. The TechNet and MSDN forums are being monitored by current MVPs and Microsoft personnel.
3) Share your knowledge in blogs, Wiki articles, white papers, and Galleries. You must create your own unique content and help build the community around your content.
4) Speak at conferences, local groups, and user groups. Speak online in virtual events. Go show your expertise and teach large groups. These conferences and events are different for every product. Go find them.
5) Become the leader. Instead of just plugging into conferences, events, local groups, and user groups, build them, organize them, and lead them. Bring the community off-line.
So even if this isn't what we want, this is what the programs have made available, and you can contact them for more information.
Thanks!
