Tips required to practice oracle dba tasks on home comp.

hi Guys,
i want to practice oracle dba tasks at home. I am guy just graduated in MS. I want to practice oracle dba tasks on my personal comp. I have oracle on linux installed.
Can some tell me in detail as to what tasks i can do on my personal comp.
it will be great if anyone lists out the tasks in detail that i can do.
there are not a lot of companies who want to hire a junior dba. I guess i am of the view that I will practice what ever i can on personal comp.
detailed answer will be highly appreciated.
Thanks a lot in advance

It's tough to practice at home because you don't really have a dynamic database that changes or experiences abuse like a real one does. Probably the best things to do are to make sure you know the syntax of parameters and views. For example, when you use log_archive_dest do you need yo include the word "location" in your setting? Or is you need to kill a session, what view will you query and what information do you need from that view? IT's always good to know about non-Oracle things too, like how to construct a .cmd file in NT or a shell script in Unix. How do you set up an ODBC driver for a non-Oracle db connection? Make sure you know how to do exports and imports (easy once you've done them a few times but intimidating the first time). Know how to check your database only using DOS commands in NT. Learn vi or another Unix text editor. Have knowledge of how a three and four tier set up works.
When you're first hired as a Jr. DBA you'll probably be doing grunt work that the senior doesn't want - like writing scripts, checking the backups and exports each morning, doing installs, etc. Make sure you know where to look for these things, how to tell if an online backup is successful or if it is stuck in online backup mode. Know OFA compliant locations. Know what and where the OFA ORACLE_HOME is. Know where the tnsnames file is, how to troubleshoot it.
Keep a sense of humor and be humble. Keep an open mind and always keep the attaitude that you can learn something everyday from someone else.
Hope this helps,
EC

Performing Oracle DBA task on Linux OS

Hi,
I an Oracle 9i OCP DBA fresher. I've been performing DBA tasks on windows XP. But, now I wish to switch to linux as dual OS.
Please tell me which distribution of linux would be suitable for me ( I've never used Linux before.). I also wish to upgrade to Oracle 11g OCP.
I think for that up-gradation, I'd have to take 1zo-055 exam. Could anyone help me getting the right material for the preparation of this exam.
Thanks .

Hello Aman,
If you have OCP already and go take teh oca and ocp exam you dont need any further courses or the sql exam as far as i know.i upgraded from ocp 10 g to ocp 11g doing it this way.Mohamed,
The reason that I mentioned your answer as wrong that you suggested the same for a fresh OCA and OCP. The person is exempted from training only if he is going for an upgrade exam not for the complete track which you mentioned in your reply.
Please see the complete track and upgrade path pages which mentions it clearly,

Additional training is not required to upgrade your certification from one version to the next.

DBA Tasks - Industry standard guidelines

Hey :
As a DBA what are the recommended tasks that we should be doing regularly?
- Daily tasks
- Weekly tasks
- Sanitary checks frequency
- Must have documented reports
- What else??
I am looking at putting a system in place for the team. Any industry standard reference and guidelines would be good starting point for me.

Hi,
Any industry standard reference and guidelines would be good starting point for me. Everybody has a differing idea of the DBA job role. I've been a DBA for 25 years, and I would say the main duties include:
Install, patch and maintain all Oracle software
Tune all Oracle instance components including SQL and PL/SQL
Approve all production schema changes
Approve changes to database design
Control all migrations of Oracle schema objects
Design and implement a backup & recovery system
Implement Oracle failover technology
In addition, in some shops the DBA's take-on responsibility for a whole new set of Oracle DBA tasks:
Data modeling and Oracle database design
Data interface protocols
Managing data security
Managing development projects
Predicting future Oracle trends for hardware usage and user load
I have more notes here:

Doesn't look like a good class to me.
I don't know what the format is but anyone calculating time to the second isn't allowing discovery or questions.
Anyone offering to teach you Oracle on VM has totally ignored Oracle's support matrix.
16 minutes on Oracle processes? Is this the speed reader's version?
Time wasted on the deprecated product iSQL*Plus.
It looks like a total waste of both time and money.
A decent class just on RMAN is a minimum of two days.

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...

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.

Take care of the Database design and implementation.
Implement and maintain database security (create and maintain users and roles, assign privileges).
Database tuning and performance monitoring.
Application tuning and performance monitoring.
Setup and maintain documentation and standards.

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 ....

Interview questions for oracle dba

Hi I am trying to find teh interview questions for oracle dba .
What will be your answer to the following questions. Can somebody shed some light...
. What is the day to day duties of oracle dba?
·     Did you use online or off-line backups?
·     What version of Oracle were you running?
·     Haw many databases and what sizes?
·     If you have to advise a backup strategy for a new application, how would you approach it and what questions will you ask?
·     If a customer calls you about a hanging database session, what will you do to resolve it?
·     Compare Oracle to any other database that you know. Why would you prefer to work on one and not on the other?
Thx
KK

. What is the day to day duties of oracle dba?
I have got a checklist, designed for my daily, weekly, fortnightly and monthly tasks. For example, in the daily checklist tasks, I check for the alert log file, competion and correction of my exports and operating system backups. DB space situation, Antivirus status, standby database status, space on disks, any rogue queries etc.
· Did you use online or off-line backups?
Both.
· What version of Oracle were you running?
8i(not any more), 9i, 10g
· Haw many databases and what sizes?
8 databases, ranging from 1 TB to 10 GB. I have segregated them into OLTP production, testing, cm, and development and a Datawarehouse.
· If you have to advise a backup strategy for a new application, how would you approach it and what questions will you ask?
How much they could afford to lose data or they want zero data loss and also I will get their requirements about down time and up time of database.
· If a customer calls you about a hanging database session, what will you do to resolve it?
First I will identify it, then see to it what exactly it is doing, capture that situation and then either try to release the locks(if its a blocking or blocked session), or kill the session, if its hanging on a runaway query.
· Compare Oracle to any other database that you know. Why would you prefer to work on one and not on the other?
Oracle passes the ACID rule with distinction as compared to the other databases. Moreover, the multiversion read consistency, recovery, flexibility and challenges of Oracle are matchless.
Cheers

Tips and best practices for translating C into LabVIEW? SERIOUS newbie...

I need to translate a C function into LabVIEW. This will be my *first* LabVIEW project. I've been reading some tutorials, and I'm still struggling to get my brain out of "C/C++ mode" and learn the LabVIEW paradigms.
Structurally, the function that I need to translate gets called from a while-loop and performs a bunch of mathematical calculations.
The basic layout is something like this (this obviously isn't the actual code, it just illustrates the general flow control and techniques that it uses).
struct Params
// About 20 int and float parameters
int CalculateMetrics(Params *pParams,
float input1, float input2 [etc])
int errorCode = 0;
float metric1;
float metric2;
float metric3;
// Do some math like:
metric1 = input1 * (pParams->someParam - 5);
metric2 = metric1 + (input2 / pParams->someOtherParam);
// Tons more simple math
// A couple for-loops
if (metric1 < metric2)
// manipulate metric1 somehow
else
// set some kind of error code
errorCode = ...;
if (!errorCode)
metric3 = metric1 + pow(metric2, 3);
// More math...
// etc...
// update some external global metrics variables
return errorCode;
I'm still too green to understand whether or not a function like this can translate cleanly from C to LabVIEW, or whether the LabVIEW version will have significant structural differences.
Are there any general tips or "best practices" for this kind of task?
Here are some more specific questions:
Most of the LabVIEW examples that I've seen (at least at the beginner level) seem to heavily rely on using the front panel controls to provide inputs to functions. How do I build a VI where the input arguments(input1, input2, etc) come as numbers, and aren't tied to dials or buttons on the front panel?
The structure of the C function seems to rely heavily on the use of stack variables like metric1 and metric2 in order to perform calculations. It seems like creating temporary "stack" variables in LabVIEW is possible, but frowned upon. Is it possible to keep this general structure in the LabVIEW VI without making the code a mess?
Thanks guys!

There's already a couple of good answers, but to add to #1:
You're clearly looking for a typical C-function. Any VI that doesn't require front panel opening (user interaction) can be such a function.
If the front panel is never opened the controls are merely used to send data to the VI, much like (identical to) the declaration of a C-function. The indicators can/will be return values.
Which controls and indicators are used to sending data in and out of a VI is almost too easy; Click the icon of the front panel (top right) and show connector, click which control/indicator goes where. Done. That's your functions declaration.
Basically one function is one VI, although you might want to split it even further, dont create 3k*3k pixel diagrams.
Depending on the amount of calculations done in your If-Thens they might be sub vi's of their own.

Future of Oracle DBA

Hello Experts
I am seeking for your guidance regarding to future of the Oracle DBA(Core).
I have following questions:
1. What areas in Oracle we need to strong(e.g RAC, dataguard,...etc.)
2. How much OS level skills are required (e.g. basic, middle, experts...etc)
3. What will be the effect of SUN and Oracle Deal on DBA's life
4. What are the extra skills needed except Oracle Database
5. Who is better APPS DBA or Core DBA
Thanks & Regards

I have following questions:Expert or not, opinions are like belly-buttons - eveybody has one. Here's mine (opinion, that is ...) ;-)
>
1. What areas in Oracle we need to strong(e.g RAC, dataguard,...etc.)Yes.
2. How much OS level skills are required (e.g. basic, middle, experts...etc)Middle, but see my response to #4
3. What will be the effect of SUN and Oracle Deal on DBA's life. I wouldn't expect much if any. Oracle RDBMS is still the company's flagship product. That won't change. It has certainly had no effect on this dba's life! My alarm clock still goes off too early. I still get home too late. I still don't spend enough time with my family or practicing my trumpet or paddling a canoe.
4. What are the extra skills needed except Oracle DatabaseSome OS, some networking, some programming in the language de juor. In my opinion no education or knowledge is ever wasted. And as a DBA you are at the juncture of OS/network/programming/system design. And everyone else always believes every problem they have is the dba's responsibility because "it has to be the database!". Network people never believe they have mis-configured a switch or router, or that they have failing hardware. OS people never believe they did any damage be deleting log files (as in .. redo01a.log). Programmers never believe bad data could enter the system, so never code to trap it. They never believe that the way they code SQL could have a detrimental impact on performance or scalability. Designers never believe the database and rdbms is anything more than a data dump.
So it always falls to the DBA to do other people's troubleshooting for them.
5. Who is better APPS DBA or Core DBA Define "better".
Define "APPS DBA"
Define "Core DBA"

DBAShell - New Open Source Project for Oracle DBA's

I'd like to have this project included in the Open Source Oracle tools list at: http://www.oracle.com/technology/community/opensource_projects.html
I've been an Oracle DBA for quite some time (since 7.0.13) and a developer for many years. One of the things I've always wished for was an easier way to set up environment variables for different Oracle Homes and a way to provide passwords to scripts without embedding them in plain-view.
About 3 years ago, I started a set of functions and scripts at my company that did exactly just that and provided many more functions for things like checking database status, running scripts quietly unless errors are detected, running actions in parallel (like fast shutdowns at once, or multiple analyzes), restarting databases in a guaranteed fashion, aliases to common folder locations, etc..
About a month ago, after putting all this time and effort into these scripts and using them in production all this time, I realized I wanted more out of the scripts like support for other databases and thought that it would be best if I gave it new life as an Open Source project.
So that is how http://sourceforge.net/projects/dbashell/ was started. Now its in a second release (DBAShell 0.85) that is more modular and would allow other people to easily add support for other OSs, other Shells, and other Databases.
Here is a description of the project from the latest news item:
DBAShell is a project based around Shell functions and scripts designed to make it easy for DBA's to use Databases in a command line environment. Currently supported is Oracle with ksh and bash on AIX, Solaris, Linux. The code base itself is 3 years old and has been in use in Production environments all of that time.
Features include:
* Automatic setting of all environment variables based on SID requested.
* Manage PATH's and other path like variables for each ORACLE_HOME needed.
* Run scripts with stored passwords (no more hard-coding of passwords!!)
* Automatically set SID based on Script location (makes it easier to share scripts between SID's)
* manage temporary script output and check for oracle errors in output
* check database status and versions from scripts
* stop/start databases in parallel (faster startup)
* compile all database objects
* analyze objects in parallel (Faster analyzes)
* set aliases and variables for common SID areas, etc..
* many helpful commands for common Oracle tasks
Over a thousand people have already downloaded the prior release and more are downloading every hour.
I'm seeking feedback from anybody that would be willing to take a look at the project, trying it out, give me any feedback you have on it, and perhaps even direct me to where I could best promote this project.
I wrote a tutorial that shows at a glance some of the more useful features of DBAShell:

Always glad to have people thinking about the poor DBA's. Usually, the developers get most of the attention in open source.
