How to Start/Stop manually an oracle 9i database with a bat file?

Hi;
I have a manual Start/Stop of the db.
How can i Start/Stop the 9i database all services with a batch file (windows 2000) ?
All in one batch files ( One for Start & one for Stop)(Including listener)
thanks for your answer !

Save the scripts below in a batch file and use the first one to start your services, and the second one to shutdown.
This script will shutdown your database first using SQL*Plus and stop the service later. This way you will avoid the timeout.
Also will ask you for confirmation if you are sure to start Oracle services and database. press Y for yes and N for No.
@echo off
%systemdrive%
REM #
echo.
echo You are about to start Oracle Services and Database
echo.
set /p Input=Do you want to continue? (Y=Yes N=No) =
IF /i "%Input%"=="Y" (goto Proceed)
exit /b
:Proceed
echo Oracle Instance and Services Startup in progress
echo.
Net start OracleOraHome92Agent
Net start OracleOraHome92HTTPServer
Net Start OracleOraHome92TNSListener
Net Start OracleMTSRecoveryService
Net Start OracleServiceORCL
echo.
echo Oracle ORCL Instance and Services Startup completed Successfully
echo Good Bye
echo on
EXIT /BSave this one in a seperate batch, again it will ask for confirmation, and shutdown the database using SQL to avoid timeout
Just replace the connect string with your own and the {SID} with your Database name
@echo off
%systemdrive%
echo.
echo You are about to shutdown Oracle Instance and Services
echo.
set /p Input=Do you want to continue? (Y=Yes N=No) =
if /i "%Input%"=="y" (goto Proceed)
exit /b
:Proceed
echo.
echo Closing and Dismounting ORCL Database
echo.
echo shutdown immediate | sqlplus "/ @ORCL as sysdba"
echo.
echo Shutting down Oracle system services
echo.
Net Stop OracleService{SID}
Net Stop OracleOraHome92HTTPServer
Net Stop OracleOraHome92TNSListener
Net Stop OracleMTSRecoveryService
Net Stop OracleOraHome92Agent
echo.
echo Oracle Instance and Services Shutdown completed successfully

How to start XML reports in Oracle Apps

Hi All,
As im new to develop XML reports in Oracle Apps. And Im used to develop oracle reports. But i have a new requirement came and i need to develop new XML reports.

2) How to make columns mapping in rtf file.
If any knows please let me know as it is bit urget for me.
Im leaving in Duabi, if any is intrested to teach me i will join or pls let me know any instute
Thanks,

Assuming that you intend to create a layout template to use against an existing report, then you should start by changing the output type in the concurrent program definition to XML. You should then run the report and save the XML file output. This will form the start point for yout layout template.
In order to create the layout template, you need to download the BI Publisher desktop. This is the add-in for Word which is used to build the template.
When you have these tasks completed, you can open up Word and you will find you have some new menu options. Load the XML data you created in the first step, and you can build your template. You will also be able to preview the output from within Word.
When you have completed the template, you need to go into XML Publisher responsibility. You should create a data definition which has a code the same as the concurrent program short name. This is the link between the template and the concurrent program.
You then need to define a template for this data definition which will have the layout template uploaded.
Having done this, switch to systeem administration responsibility, select the concurrent program menu entry and query back the program you are workin on. Click on the 'update' icon. You then need to click on the 'Onsite setting' tab. This allows you to attach the template to the program.
Hope this helps.

So how i can run the new address link You mean that after the restart of teh machine, EM doesn't work? Did you check that whether the service of the EM is running or not?
emctl status dbconsoleIf it shows that the EM is not running then you must start teh service using,
emctl start dbconsoleAnd also check that you are not using DHCP, in case of which EM would keep on crashing since the IP would be changed all the time. For this, you must ensure that you configured EM using a static IP only.

HOW TO START MAKING DATABASE USING ORACLE SQL PLUS in 10g?

how will i create database using sql plus?
does the code of sql applicable to it..?
do i have to use the "create db <database name>", use and " create table also,.."
pls help me..
thanks

At dos prompt :
C:\>set ORACLE_SID=<your SID>
C:\>sqlplus / as sysdba
you get connected as sys user. Don't use this connection to create your own objects, create users instead.... but it would be useful to read some documentation, for example Starting SQL*Plus and manuals mentioned there.

Path to become a DBA

Hi buddies,
I do have something crawling in my mind.
Would like to know whats the path to become a DBA. I did my OCP around one year ago in Oracle 9i DBA track.
Now working as a database executive, where my job task is to provide support for the client in generating reports, counts, batch load and many many more things in maintaining the database. I also spent 20 % of my working time in PL/SQL, web PL SQL, and so on.
My SQL has improved dramatically.
I have been here for 6 months.
Is this a way to become a DBA as well?
Is there a lot more to learn being in this track? I believe being strong in SQL is equally important for a DBA but its just my perception. Please do comment. I am not doing anything to do with DBA tasks except for small things like creating tables, job scheduler and so on.
I am a completely different person now compared to when I stepped in. I have worked before but nothing to do with Oracle.
Please advice. Is this how we start off to become a DBA or am I totally in a wrong track?
Hope to hear from all of you.
Thank You so much.

I also spent 20 % of my working time in PL/SQL, web PL SQL, and so on.There's a good indication that a job title can mean anything at all . . . and nothing at all. In my part of the world, the term 'executive' automatically means someone above mid-management level. (and even that is not a precise description) Certainly not someone who does the low-level work you describe. A "database executive" calls to my mind something akin to a CIO.

Re: difference between Oracle Apps DBA and Oracle ERP Consultant
Re: Future of Oracle DBA
I'm always amused and confused by questions about career that seem to indicate a beliefe that one punches certain tickets then applies for a job description that somehow magically matches. DBA (no matter how you describe it as "core", "apps", "executive" or whatever) is not an entry level position. Anyone who hires someone into a DBA position without some proof of real-world experience is not a company I'd want to work for. So, one gets into a DBA position by doing a good job at what they are currently doing, develop a good working relationship with the DBAs there, show an aptitude and let it be known what you are doing on your own (self study, practice on you own system, etc). An opportunity should eventually present itself. In my own career, beyond my initial job in a designated 'trainee' position, I've never sought out a change of job responsibilities ... they always came to me by the process described in one of the threads referenced above.

Become a DBA, SQL ? Oracle? Both?

HI everyone,
I am wanting to start my journey to become a DBA.
I do not want to take any shortcuts and want to do this the best way possible. I realize this will take years, but I am stubborn and determined , no matter what I do.
I am concerned that I go down the correct path right from the start.
to give you some background, I am currently an IT Administrator for a business unit of ATS Automation.
I am responsible for around 125 users and counting.
We currently Use SQL 2008, thats where my confusion starts.
Do I start with some SQL learning before Oracle? I have seen this suggested in another thread here.
I am not sure whether I should have my sights set on being an Oracle DBA or SQL or is Oracle an extension on SQL? it seems that way to me by reading the other thread.
I think that in the end I want to be an Oracle DBA. I just want to be sure that I know before I even start my Education of databases, that I know where it is that I need to be.
I know that to be a great DBA one must know what and if possible how the Programmers are thinking, for communication reasons. And also what the Business needs to get out of the Database.
Could anyone please suggest books and the proper sequence that I should be starting this endeavor? as well as answering the other Questions I have in this thread.
Thank You in advance for all of your answers, I know they are going to be great!

Stubborn and determined is a substantial portion of the requirements! Another portion is to be able to instantly change to flexible and open-minded.

I think that in the end I want to be an Oracle DBA. I just want to be sure that I know before I even start my Education of databases, that I know where it is that I need to be. The real problem with giving advice here is the range of what DBA means. In some places, it just means a super-duper developer. In other places, it means being able to change rapidly from a nerd in the corner decoding trace files to a strong unyielding pointy headed boss defending the production database from the heretical developers. In still other places it means being able to work as interchangeable cogs in a team. The upside of this is, whatever your strengths are, you can find a place that plays to them. The other side is you may be happier doing something else.
>
I know that to be a great DBA one must know what and if possible how the Programmers are thinking, for communication reasons. And also what the Business needs to get out of the Database.I'm not convinced there is any formula, though those and a positive attitude are certainly necessary. All I can say is try it, see if you find you are loving it, bail if you are not. By the time you are into it for a couple of years, things may be quite different anyways. The trend is for many of the boring junior dba tasks to be automated or gui'd, but the unspoken secret is there will be demand for those who have a range of knowledge and depth of experience to figure things out. Virtualization, disk technologies, app technologies, web technologies and all their interactions with the db and the business will fall under the DBA purview, though it may change in name.
