Thanks,
RahulFor future growth, there's no such thing as wasted education. Real career growth comes from having good knowledge from a broad range of subjects and being able to bring that knowledge together to solve problems. It doesn't come from attending a specific course on a specific subject and letting that define a specific job title and/or letting a specific job title define the specific tasks you do on the job.
The most valuable people in a business are not those who narrowly define their jobs by the last formal class they took. They are people who define their jobs as "problem solver".
I would look at studying Oracle apps as an expansion, not a shift. As would studying networking .... and unix systems management ... and storage management ... and data anlysis .... and business systems analysis .... and human behavior .... and ... and ...

Which has better opportunities Oracle DBA or Oracle Applications
Hello,
I am a fresh MCA candidate currently working in infosys as a Software Engineer. i would like to switch either to Oracle Apps or Oracle DBA. But I am unable to decide which will have better career opportunities.
Regards,
Amjad Khan>>
As a fresher can I apply for ORacle Apps Jobs after completion of my OCP certification.

Oracle Apps has new certification and if I am nost wrong, it is still in beta.

Is Oracle DBA a higher level then Oracle Applications ?

For me, as a CORE DBA, Oracle Apps doesn't excite me much because I can't play with Oracle Apps database as I do with the CORE database.
There are other areas which should be considered as an Apps DBA.

5 Year MSSQL SERVER DBA to ORACLE DBA 11g ( ORACLE ENTERPRISE LINUX )
First of all thanks in advance for reading this thread.
I'm a senior consultant with 5 year experience as MSSQLSERVER DBA.
My company is starting new projects using ORACLE RAC 11g on ORACLE ENTERPRISE LINUX, I would like some guidance to enter the linux & oracle world.
I have some linux basics & oracle basics, but i would like to follow a learning path.
I would be very appreciated if someone help me.
Thanks in advance !concepts manual: [ http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/toc.htm|http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/toc.htm]
you can also search for any Oracle User Group in your area and join them. Most people there are willing to give helping hands in many areas, and often it's easier to discuss problems, or even attitudes with a beer or another than only in a forum. (my personal opinion)

Advice on Oracle DBA Associate (OCA) Certification
Hi, All
i'm a newbie to Oracle. I was given a task of passing Cetrtification Exam 1z0-042 for
Oracle DBA (OCA - Oracle Certified Associate)
which is the lowest certification level for an Oracle DBA.
My Q: what Edition of Oracle database should I use in my preparation for the Exam: Oracle Express Edition OR Oracle Standard (enterprise?) Edition?
I started to use E-learning materials from Oracle and I see that most of the examples are given referencing Oracle Enterprise manager, which is not the part of Oracle Express Edition [if i'm wrong pls correct me]
Thank you in advance for your help
If anyone needs help with regular expressions, feel free to stop by at
http://regexadvice.com/forums/68/ShowForum.aspx
where I'm one of the [unoffical] moderators.
Sergei ZFor DBA learning, you'll want to use Enterprise Edition with all the bells and whistles (partitioning, RAC, bitmap indexes, you name it). Its free to download for this sort of purpose.
Check out www.dizwell.com for articles on installing Enterprise Edition (through VMWare or directly) on various platforms. -
Difference between Oracle Apps DBA and Oracle ERP Consultant
Dear All,
Can any please give me some idea about the difference between Oracle Applications DBA (apps dba) and Oracle ERP Consultant.
Which career is most rewarding one in terms of Salary, Job Security and Least amount of work
I am working as Core DBA which career will be most suited to me and easy to learn
Which Module of Oracle ERP is most used and would be suited for me
I have done Oracle 10g DBA certification what certifications would you recommend to me
Any help in this regard is highly appreciated.

"Which career is most rewarding one in terms of . . . Least amount of work"
"which career will be . . . easy to learn"
Since "easy" and "least work" seem important to you, I'd suggest a career in something besides IT. I could make some specific suggestions but run the risk of insulting people who work in those areas. -

Which is a better carrer option,DBA or oracle apps developer,please help?
I am a trainee and have been offered a choice between the oracle DBA and the oracle apps finance developer.
What is the future of a DBA guy ,can he get into the management side in an IT industry or just stick to the tech side all through the life?
Is getting into a managerial side more easier in the DBA or the apps developer side?

Mahen,
Before giving an opinion, the most relevant part would be to know that you want to do what, be a manager or be a techie or both? AFIK, in the dba track as well, after few years, a person can become a manager , project/team lead. It all depends on this fact tht you want to be a manager or not. I have got couple of friends, some are managers but some chose to stick with technology only despite that they were offered to become a manager as they didn't like the idea of analyzing the appraisal reports than Statspack reports.
Getting into the manager side would only come(or should come) with a proven record. I am not from Apps background, never did that but I feel that's a more functional side that you have mentioned. If you are a finance guy, having a strong base in finance, you should go for it. I don't think that if you are not having a base in this stream, you should be opting for it. You are still a trainee as per your saying, think about being good in either side of the technology than being the manager. You can always be once you have spend some time with either of the tracks.

Experienced Oracle DBA want to become Apps DBA and need guidence
Hi Apps Gurus,
I am an experienced Core Oracle DBA having 7 years of experience in Oracle Database Administration. I have always been interested in Apps DBA but never got suffient time to pick that up. This time I have taken a months's leave to be able to spend time and gather Apps DBA knowledge. I need a thorough knowledge in Apps including the very basics and architechture. I dont want to jump into advanced skills without having my basics strong. Please guide me with steps/milestones to be identified and achieved. I would appreciate if somebody can give me an idea regarding how much time it generally takes to pick up to a level where the candidate can work as an Apps DBA.
Any suggestion and guidence is appreciated.
Thanks.
A.DHi AD,
I am looking for the same thing here, after doing 6 years of Core DBA job, i was looking to have some aaps dba exposure, but still could not find any thing except some ebooks, let me know if you find some thing ................

Difference between oracle 10g dba and oracle 11i apps dba
hi
can any one please explain this.
thank youHi,
can any one please explain this.An Oracle Applications DBA is very different from a regular Oracle database administrator and requires specialized skills in business administration and Oracle application server architectures. The Oracle Applications DBA job role is less compartmentalized than a traditional Oracle DBA and the Oracle Applications DBA must also have skills in these areas:
Database Design - Many shops require customized functional extensions and reporting data marts and the Oracle Applications DBA must have outstanding Database design skills.
Oracle Application Server - The Oracle Applications DBA must understand the internals of the Oracle concurrent manager and understand how to monitor and tune Oracle Applications.
Functional Expertise - Many shops requires a business degree and a general understanding of the Oracle Applications module. For example, accountants are widely used to support Oracle eBusiness Suite (Oracle Financials), and accountants with an IT background are easily trained in Oracle Applications DBA support.

Are the oracle DBa's seeing an end to their career
It's been 2-3 years i am working as an oracle dba in a mid range shop and i was pretty happy with it. After having the satisfaction , I was always worried about the future of an oracle dba. I always heard sql server and db2 are much much better than oracle as they are less complex to administration and their cost is less. Though the oracle people would talk about performance and scalability but with the recent releases , those db have overcome those problems. The problems for oracle dba are coming from several ways:
1.Companies are shifting for sql server or db2 as for low cost and low required of man power.
2.Oracle itself becoming automated.
3. Company like IBM offering main frame solution with free db2 database for the entire data center.
4.With the concept of Cloud computing storage would be third party location , where few employee can take the responsibility.
And..many moreeee...
It gives me a COLD feelings what would i be doing in 3-5 years from now and how could a dba would evolve himself with the change??? I hope this time i am not right.. all the points that i showed is wrong...

In next N years ultimately everything in RDBMS will be automated.
This is a common trend and Oracle is leading flagship in it.
Ultimate goal, as I see, is to eliminate DBA, minimizing cost of ownership.
This will attract business to such products - self-managed software.
I do not see it to happen tomorrow, though. But it is going there.
Yeah, well 30 years ago the experts were predicting the end of the need for programmers (the old term for 'developers'). "End User Computing" would put the power in the hands of the business users and eliminate the entire IT department. No I'm not exaggerating. That was the prediction. And people like you were insisting it would come to pass.
You don't even have to go that far. Look at the predictions for the 'paperless office' . . .
Many here will argue with me, but look of the definition of DBA

DBA Responsibilities
Installation, configuration and upgrading of Microsoft SQL Server/MySQL/Oracle server software and related products.
Evaluate MSSQL/MySQL/Oracle features and MSSQL/MySQL/Oracle related products.
Establish and maintain sound backup and recovery policies and procedures.
Take care of the Database design and implementation.

Interface with MSSQL/MySQL/Oracle for technical support.
ITIL Skill set requirement (Problem Management/Incident Management/Chain Management etc)
>
Well, that's ONE "definition" of a DBA. It's far from "the" definition.
I'll tell you what. I've actually sat on committees that drew up lists like that. I can tell you first hand that while a lot of things on the list may look legit, there is also a lot of pressure just to fill up the list with as many things as possible in order to justify head count to the bean counters. You could just as well add 'weekly cleaning of the left-hand smoke shifter.'
Then lets look at them one by one:
Installation, configuration and upgrading of Microsoft SQL Server/MySQL/Oracle server software and related products.How often Installation happens? Once for one new app. Usually app vendors have recommendations that DBA should follow. So, what is DBA's role here? Start installer and to follow.
Configuration and upgrading will be more and more automated.
Except the app vendor left out critical details they didn't think were critical because they don't understand the database. Or have bogus 'requirements' because they don't understand the database. Or their recommendations were based on how they did it in their pristine development lab and they never even knew about critical dependencies that might not exist outside of their lab.
Week before last I spent 50 hours working on installing a new database based on the app vendor's specifications ....
Evaluate MSSQL/MySQL/Oracle features and MSSQL/MySQL/Oracle related products.Again, how often? When new App is about to be created and designers need to choose which DB they will need.
And then they proceed to develop on rdbms-A using best practices they learned from rdbms-B -- which turn out to be worst practices on rdbms-A. And only when they go live do they discover that their design doesn't scale because they tried to re-invent (poorly) functionality built into the database.
Establish and maintain sound backup and recovery policies and procedures.Again, how often yo need to establish policies and procedures? Every time you put in a new app with a different SLA.
Backup itself is 100% automated already today. Only if you buy off on the lowest common denominator.
Recovery is close to 100%.Oh? Go spend some time in the RMAN forum ...
And even if it were close to 100%, 'close' only counts "when playing horseshoes or hand grenades."
Most of enterprise backup software support backup and recovery of major RDBMSs.
Just specify a date "from" and click Go.
A little bit complex with RMAN. You have to type(!) RESTORE DATABASE; RECOVER...
Until the cause of failure was something the automation didn't anticipate. Or you then discover that your 100% automated-out-of-the-box backup didn't work the way thought it did. Oh, it 'worked' all right. Just not the way you thought it did.
Take care of the Database design and implementation.Where? Only in development shops.
Depends on what you mean by 'database design and implementation'. And most companies have some sort of development, even if they don't recognize it or call it that.
Implement and maintain database security (create and maintain users and roles, assign privileges).Centralized enterprise security (Domain etc) are in use. Many apps have their security and use basic RDMS security to login App running user.
Until such time as "nothing changed" but "I can't connect to my database".
Database tuning and performance monitoring.Greatly automated. Ultimately will be 100% automated.
Until it's not. See my comment above about developers.
Application tuning and performance monitoring.There are enterprise solutions for monitoring. Also Oracle has Grid Control.
Application tuning can be done by app vendors.I've NEVER met an app vendor that knew **** about how their app impacted performance. 100% of them throw it back on the DBA. I had an app vendor tell me that Oracle was incapable of sustaining more than five concurrent connections.
DBA cannot tune App itself. It may only modify some things in DB that will perform better. And this will be automated.
No, because the database cannot anticipate what stupid things the vendor may do. And it can only work with what it is given.
Setup and maintain documentation and standards.How often?
As often as anything that is documented, changes. As often as it is discovered that something that should be documented, isnt'
Plan growth and changes (capacity planning).Well, DBA should do it. But, again, how often?Should be almost constantly. Given budget cycles, you can't wait until your disk is 98% full before asking to buy more.
>
Work as part of a team and provide 7×24 supports when required.Where such 7×24 support policy exists.Look at my comments above about how these lists get created in the first place.
I can tell you from experience that such 24x7 policies are more common than you seem to think. Just about any financial processing business, logistics and transportation business, telecom business ...
And what from above should be supported during a night by a human?
I see just a restore/recover DB, because a human should make a decision "From which Date".
Do general technical trouble shooting and give consultation to development teams.Yes, in Dev shops. Most of shops are not development shops, though may do custom and ad-hoc reporting and small app development. Do they need a dedicated DBA for this? I doubt. Either a developer will be (self)trained to do some DBA's tasks or DBA will become a SQL developer in that team.
Interface with MSSQL/MySQL/Oracle for technical support.Oh yeah... :)
ITIL Skill set requirement (Problem Management/Incident Management/Chain Sure, two days of training to know basics of ITIL to understand what manager of Helpdesk (Support and Incident Management Team) is talking about.
So, I see DBA should go in of 3 directions:
1. Very deep technical expert that can help in some rear and difficult cases. How many of them will be needed?
2. SQL/ETL/etc Developer. There is not much automation in software development yet.
3. DB Design and Architecture. How many of them will be needed? May be more that #1.You seem to think that automation will solve everything. Take that to it's logical conclusion and it will put all of IT out of work. See my comment above regarding "End User Computing'. What you forget is the human element. Not the human DBA trying to do things you think are or soon will be automated. No I'm talking about the humans that create the kinds of problems that automation is *always* trying to catch up with. Pointy Hair Bosses dreaming up new requirements. Bean counters refusing to by an additional 10 gb of disk. Developers that refuse to learn and/or follow best practice. Developers that can't think beyond clicking an icon to create a table. Developers that treat an rdbms as a data dump and try to use Java to re-invent every bit of functionality the db already provides. Systems administrators that delete all of your online redo logs because he needed disk space and 'log files are expendable'. End users that forget their password *EVERY F****** DAY!*
No, I don't spend my time managing extent distribution like I had to do with 8i. Yes, a lot of things I had to do manually in 8i are now successfully automated to the point I don't have to do them .. or have simply been engineered out of the system. But no amount of automation will overcome the ways humans (Executives, managers, supervisors, other IT team members, and users) figure out how to bring a system to its knees.
This whole discussion reminds me of Dippin' Dots. "The Ice Cream of the Future". Well, it's been "The Ice Cream of the Future" for almost 30 years ....

Recommended OPEN CURSORS setting for Oracle serving a web app
G'day
Hopefully Phil is still lurking here, so might see this. Or anyone else that knows about Oracle.
I've always thought the default for "maximum pooled statements" setting for an Oracle DSN - which is 300 - is way too low to be sensible for a web app (which, let's face it, any CF DSN is going to be used for!). I usually find I end up with it up around 1000-2000, depending on the sizeof the app, and how busy it is.
I'm adequate with monkeying around with Oracle, and have needed to do a moderate bit of that sort of thing in our dev environment, but I am by no means a DBA, so it's all very seat-of-the-pants.
So I'm keen to know what other people have their maximum pooled statements / open cursors setting set to for their Oracle-driven web sites/apps.
One of the reasons I'm asking is that I wonder if it might be worth while to suggest the default for CF9 is upped to 1000 or so..?
Thoughts / comment?
AdamI personally would not set the limit any higher than 300, and I'd consider keeping it even lower.
Each pooled query / open connection is imposing resource-burdens on both the CF and the Oracle servers by creating what might be thought of as "a very crowded restaurant." Most of them are just standing around, but they nevertheless are occupying the restaurant, and the potential exists that every one of them might try to order a burger-and-fries at exactly the same time.
The "number of pooled statements" should be such that your SQL-server can actually handle that number of simultaneous requests, both in terms of active searches and of maintaining the still-open result sets. Beyond that point, incoming web requests should be forced to wait. Set an "occupancy limit" to your proverbial restaurant such that everyone could come in and be timely served at the same time.
Categorically, if you plot out response-time graphs about such things (SQL servers, virtual memory subsystems, and so on), they exhibit a fairly-linear performance curve up to a point, after which "the elbow- or knee-point is reached" and beyond that point it becomes exponential in a very, very bad way. I saw this happen in a batch-processing subsystem long ago on a very small mainframe: (yeah, I'm makin' these numbers up...)
Number of Jobs at Once
Completion Time per Job
1
30 seconds
3
40 seconds
8
9 minutes
12
4.5 hours
It was just-about that bad. And what I did to (dramatically...) address the problem was to impose simultaneous-job limits on that subsystem. As long as the number of simultaneous jobs was constrained to "less than 3 at a time," a workload of 12 jobs could be reliably completed in (4 * 40) seconds, whereas if all 12 jobs tried to run at once, the computer would have reason to file a lawsuit for abuse. -
