Need help in database industry

I am doing a project in Database Software Industry and will very much
appreciate if you can help me understand the following:
1) What database do you currently use, what Operating System it runs on, and
are you using any database options?
2) Over the next 6 - 12 months are your going to buy more database or any
databse options, if so which ones?
3) What do you like the most in your current database product?
4) Any specific issues you find in your current product?
5) Are you using any open-source products, if so which ones and for what
prime reason?
6) How would you compare Oracle, DB2, MS-SQL , Sybase and OpenSource?
7) Are you switching any database in favor of an alternative - if so which
ones?
8) What trends are you seeing the the database market in general?
Thanks

I was glad I came across this note. I recently started a tutorial on J2EE , and have run into exactly the same error. Have you found a solution? Can you share it with me?
Thanks.....

Need help with database configuration

Hi all,
I have an Oracle 9i release 2 Database running on Windows server 2000. There I intend to insert data using a consol application. The program runs fine from other machines connected to it through lan and data is inserted all right. But when I run the program on the same machine as the database server, it gives the following error message
"ORA-01843: not a valid month
ORA-06512: at "FASTDB.SPINSMODSALESCENTERSMESSAGES", line 16
ORA-06512: at line 1 .."
The program is written in C# and the server has .NET FrameWork 2.0 and MDAC 2.6 installed.
I don't understand if the program were wrong, then how does it run properly from other machines. And if it runs correctly on the other machines then why doesn't it run on the server machine..
The procedure looks like this
CREATE OR REPLACE PROCEDURE SPInsModSalesCentersMessages(pv_1MessageId integer,
     pv_2requestMsgs varchar2,
pv_3replyMsgs varchar2,
pv_4messageStatus integer,
     pv_5outStatus out integer,
     pv_6SerialNo varchar2,
     pv_7SaveDateTime varchar2)
AS
vn_IsMsgsId integer;
BEGIN
     pv_5outStatus:=-1;
     SELECT count(1) into vn_IsMsgsId
     FROM TBLDataTranc_Client
     WHERE TBLDataTranc_Client.messageId = pv_1MessageId;
     IF vn_IsMsgsId = 0 then
          INSERT INTO TBLDataTranc_Client(messageId,serialNo,saveDateTime,resquestMsgStr,replyMsgStr,messageStatus)
          VALUES(pv_1MessageId,pv_6SerialNo,to_date(pv_7SaveDateTime,'mm/dd/yyyy hh12:mi:ss AM'),pv_2requestMsgs,pv_3replyMsgs,pv_4messageStatus);
     ELSE
          UPDATE TBLDataTranc_Client
          SET      resquestMsgStr=pv_2requestMsgs,
          replyMsgStr=pv_3replyMsgs,
          messageStatus=pv_4messageStatus,
          serialNo=pv_6SerialNo,
          saveDateTime=to_date(pv_7SaveDateTime,'mm/dd/yyyy hh12:mi:ss AM')
          WHERE TBLDataTranc_Client.messageId = pv_1MessageId
          and TBLDataTranc_Client.messageStatus =1;
          pv_5outStatus:=1;
     END if;
end;
Please help me if you can.

Need help regarding database connection

hello
iam new to j2ee i am using Jsp,Ejb and Jboss server i need to connect to the oracle database with the above configuration wher can i find the tutorials can anybody help me please

a word of advice - if you're new to jsp, jboss, and ejbs, and obviously know nothing about jdbc either, this isn't the way to learn it.
start with the jdbc tutorial and see if you can get a single java class to connect to a database and execute some sql. then work up from there.
what you're doing is something known as "biting off more than you can chew".

Need help with database migration using export/import

Hi,
I am planning to do a database migration from 8.0.6 to 10.2.0.4. I am using export/import. Please answer some of my queries:
1) Do i need to do full export using SYS/SYSTEM user.
exp80 system/manager file=c:full.dmp log=c:\full.txt full=y consistent=y
2) Will there be any data corruption while export.
3) Is export/import the only method of migration/upgradation.
Please help
Thanks.

I'll answer the specifics that I know about your questions, but please look at the post from Srini for additional info:
1) Do i need to do full export using SYS/SYSTEM user.
exp80 system/manager file=c:full.dmp log=c:\full.txt full=y consistent=yA full export will move as much information (metadata/data) as possible. In order to do a full export/import, you need to do this from a
privileged account. A privileged account is one with EXP_FULL_DATABASE for export and IMP_FULL_DATABASE for import.
2) Will there be any data corruption while export.The data in the objects that you are exporting is being read, nothing is written to user data. I'm not sure what this is available in 8.0.6,
but if you need a consistent export, look to see if consistent=y is available in 8.0.6. All this means is that the dump file created will have
consistent data in it.
3) Is export/import the only method of migration/upgradation.If you are changing hardware, the only supported way from 8.0 to 10.2.0.4, that I know of, is using exp/imp.
Hope this helps.

Need help on database capasity planning

Hi All,
Basically I am JAVA developer, I need database help.
User Interface(UI) screens design was completed as a part of Requirements study. Is there any way that to do database capasity planning and load in future?
Thanks in advance,

What we usually do in our shop is do some basic DB design as part of the requirement gathering stage. Just a quick idea of what the tables will look like, what queries will run, etc.
This helps the DB team plan the db requirements, because once you know what data will sit in which table, you can say things like "This table will be populated once with 300 rows, that table will get about 3 new rows a day, but the other table will get 3000 new rows every minute", and now you know that as part of your requirements you show decide how long you want to keep data in that huge table (delete data older than a week? month? year?) and this allows you to calculate hardware requirements (especially diskspace, memory and IO). Then you look at the queries and get started about indexes...
That was a huge question you asked. I hope this gave you some sort of a clue where to begin.
BTW. If you find that you have lots of huge tables that grow fast, this may be the right time to hire a DBA :-)

Need help connecting database in Dreamweaver MX

I'm using Dreamweaver MX, XP Pro and IIS. I installed the
latest version of PHP (5.2) and have mySQL and the ODBC driver
installed.
I set up the testing site in Dreamweaver. Yet, Dreamweaver
cannot locate my database(s).
I followed steps to edit the PHP.INI file to work with
Dreamweaver correctly, yet it's not working. However, now instead
of getting "An unidentified error has occured", I'm getting the
vague "HTTP Error Code 500 Internal Server Error" error.
PHP was installed manually at first but that didn't work
right so I reinstalled it using the auto install. It should be
accurate, only I can't see where I would enter the path to the
database files; there is no line for that in the SQL section. But
it's in the default directory so it should know where it is
automatically ... ?
Help???!!! Can someone walk me through the steps to see why
it isn't pointing to the databases?

Hi,
The "DB-SYSTEM-NAME" is nothing but the business service which is defined for that database in your Integration directory. In this business service only you have to define ur jdbc communication channel. So by giving the details of BS and CC you will get the DB connectivity during runtime.
Cheers!!

NEED HELP WITH DATABASE WEB SERVICE INTEGRATION

Hello everybody. I have created a web service with returns a list of records extracted from a database. It works, Apex references the web service and get the result when I test it, but I want to display results in a page type "Form and Report on Web Service" and when I associate the web service to the page and click on "Finish Button" I get this message:
"This Web service does not have a result tree in its definition that is appropriate for a report. You may wish to run the Form on Web Service wizard instead.".
It is correct, of course, but I do not have an example of how to do an appropriate definition for this kind of report.What kind of definition is it waiting for? What I do in the web service is to return a list of items (a resultset of a query such as "SELECT PRODUCTID, PRODUCTNAME, PRICE, IMAGEHREF FROM PRODUCTS") concatenated in a string (commas-separated values). What kind of output must the web service produce or how have I to structure the associated wsdl document in order to display the result with a "form and report on web service" page?
Every help or example is welcome.
Thanks a lot and have a nice day

Any help is appreciated

1. Don't do 'SELECT *' it's yucky, and you never know what your gonna get.
2. In one point you are doing getInt and two lines later you are doing setString, on the same column. I think the driver is asking you to make up your mind.

Need help with database connection and trasaction!

Hi, I'm trying to load data from a huge report to DB2. My old way of doing this is: 1. using DriverManger.getConnection to get a connection.
2. Then set autoCommit to false.
3. Keep the connection open.....
4. con.commit once I reach a section, let's say around 5000 records per section.
5. Close the connection once I finish loading, (Finally block)
I'm still new in the java world and kind of concern of the way of what I'm doing. Then I did some research. Perhaps using javax.sql.DataSource is a better approach. But I couldn't use it in WSAD. Do I need do some configuration? I heard it's in j2ee 1.4 . Is that the reason I couldn't use it?
And.......I tried to use DAO pattern to talk with DB. By that way, I have to open and close connection everytime I invoke the dao method. Then how can I control the transaction? Because I don't want to insert each record data in to the table right away. I want to do the commit once I get all records for one section. No idea how can I achieve this.
Any suggestion will be really appreciated!!!

Student needs help with database planning

Preliminary Plan
I work at the headquarters of a small company of 8 offices and 26 employees. I am the central database system. Right now, information is only accessible through me, by me, from me, and to me via fax, phone, mail, or email. I have several spreadsheets with different information resulting from personal information, cell phone information, laptop information, government vehicle information, contract information, and training information.
I want to develop a database that will automatically keep track of this information as entered by the user. Whenever there is a change or update, the system will be able to automatically accept this information into the system. Information will come from each workstation in the office that only the managers and I can see. The managers will however only have access to their individual employee information, but I will have access to ALL the employee information. All information created, provided, and maintained between me and the managers will be conducted through RDBMS. Triggers will be used so that information can be updated or inserted through SQL. LAN-to-LAN connections are already in place so that information on the network can be accessible. Preliminary plan is as follows:
WEEK 2: January 15-21, 2007
Develop preliminary plan for two sentence concept of BPS
WEEK 3: January 22-28, 2007
Finalization of preliminary plan
Creating the database i.e., connecting, granting privileges, adding systems
Designing and creating tables, databases which are already in spreadsheet format
WEEK 4: January 29-February 4, 2007
Designing and creating tables, databases which are already in spreadsheet format
Installing, configuring, and securing the database;
WEEK 5: February 5-11, 2007
Develop triggers using SQL; test database
WEEK 6: February 12-18, 2007
Design, develop, and test user interface application
WEEK 7: February 19-25, 2007
Test application again. Test database again. Test project application and database together.
WEEK 8: February 26-March 4, 2007
Finalize project details to incorporate into a PowerPoint presentation for submission.
WEEK 9: March 5-11, 2007
Demonstrate and present project. Evaluations due.

My major is information system. I want to be able to
access information from all 8 stations where the user
inputs the information, but only have access to their
employees and I will have access to all 26 employees.
I being the central database system.Still quite vague, if you ask me. If it's just an entry formular with user authentification, your time schedule may work. Installing XE and developing with APEX could just be the right tool for this job, but without any further information (data structures, authentification concept, user interface) it will remain pure speculation from my side. Why not ask your teacher if he/she thinks your plan is reasonable?

Need help with database error

hi i get this error when trying to create a program -
> Could not allocate space for object 'SNAP' in database 'D01' because the 'PRIMARY' filegroup is full.
can someone tell me how to fix this problem.
thanks in advance

Yes,
Wat version of SQL are you using?
For SQL 2000 logon to Enterprise Manager, from the console window navigate to the database and check the name of the database that you have provided. right click and go to properties and check the "datafiles" tab. At the bottom of the screen you will find file properties, check wat are the properties.
also you can delete the data from SNAP table by running some standard progam "RSSNAPDL". Refer SAP Notes 11838, 40918 and 126974 and then implement the program in your system so that the SNAP table doesnt get full.
Thank you
