Create a database - MS Access + JFrame.

I have a quiz application that writes questions and answers to an access database and a second app that retrieves them and then gives you a score - with hints during and explanations at the end. It is well.
What I would really like to do is to use a 'template' empty database so that when data is written to it it creates a new table and preserves the template for the next usage. Sorry if I've missed something obvious, but I cannot find this in the API, any clues /hints are welcome.

Thank you - it was one of those things that I thought there might be a java magic 'tool' for, but this is a workable solution.
Any other links - ideas?

How to create a read only access for database

I am developer but willing to lear some of the dba tasks. I would like to know the steps that i need to take to creat a read only access database that is going to be used for the report development.
I really appreciate if you tell me all the steps I need to create that. I have a full right to do this in the develpment database. thanks

thank you for your reply but it does not tell me how i can set up a read only access acccount for the user. Do i need to create a role and assign the role to the users?

Create a database link to access SqlServer 2005 view from oracle 11gr2

Hi All,
Greetings for the day.
Though I have seen quite a few posts but just wanted to cross-verfiy and double check hence posting.
Oracle Database : 11gr2
OS :SOLARIS SPARC 64 Bit
SQL Server Database : Sql Server 2005
OS : Windows 2003 32 Bit
The requirement is to access a view residing in the SQL Server 2005 Database using the Oracle Database. This involves creation of a Database link in the Oracle Database to access the SQL Server.
Can you suggest which approach should i follow ( I am able to understand that both do the same job ):
How to Configure DG4MSQL (Oracle Database Gateway for MS SQL Server) 64bit Unix OS (Linux, Solaris, AIX,HP-UX) post install [ID 562509.1]or
How to Configure DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX Itanium) to Connect to Non-Oracle Databases Post Install [ID 561033.1]Will they do the same job ? And can they be used on any OS and version of the SQL Server Database as version information for SQL Server is not specified anywhere?
Please let me know so that I can it forward with Business for approvals and budgetting.
Regards
KK

Your question is similar to the post: Oracle 11gr2 connection to Sql Server using dg4msql problem
Please visit: http://stackoverflow.com/questions/4658942/oracle-11gr2-connection-to-sql-server-using-dg4msql-problem
Answer on the website:
You seem to be using the Gateway for MySQL set-up rather than the Heterogeneous Gateway (for ODBC connections). Here is an overview of the process
On SQL Server create a database user and give it read access to the database/tables you want to read via the Oracle database link.
In the gateway home each SQL Server database you want to access should have an init.ora located in $OH/dg4msql/admin in the form initsid.ora where sid is the name of the database to be used in the link (e.g. initbob.ora), so create one
HS_FDS_CONNECT_INFO=msserver1:1234//Example_Database
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_RECOVERY_ACCOUNT=RECOVER
HS_FDS_RECOVERY_PWD=RECOVER
HS_TRANSACTION_MODEL=READ_ONLY
You must now add the new sid to the listener.ora in the gateway home using an additional SID_DESC section inside the existing SID_LIST, for example
(SID_DESC =
(SID_NAME=bob)
(ORACLE_HOME=/oracle/gateway/product/11.2.0)
(ENVS=LD_LIBRARY_PATH=/oracle/gateway/product/11.2.0/dg4msql/driver/lib;/oracle/gateway/product/11.2.0/lib)
(PROGRAM=dg4msql)
You should now stop and restart the gateway listener so that the new sid becomes active. NB a reload is not enough.
You must now add the new sid in the tnsnames.ora file for the listener of each database in which you will create a link. You don't need to do this in the gateway home unless it is also a database home in which you will create a database link.
bob =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = severname.example.com)(PORT = 1690))
(CONNECT_DATA = (SID = bob))
(HS = OK)
NB: The host and port are for the gateway not for the SQL Server database
In each database that requires a link to the MS-SQL database you should create a database link to your new gateway sid.
CREATE PUBLIC DATABASE LINK bob
CONNECT TO "ms_user" IDENTIFIED BY "ms-passwd" USING 'bob';
where ms-user and ms-password are the SQL Server user you created right at the start.
Now you can test the new database link
SELECT COUNT(*) FROM "Table_Name"@bob;
Once you have this working you can alter the initsid.ora file to add parameters to suit your connection. If you do it this way you can easily add and manage many different databases via the gateway.

Manual script to create database for Access Manager installation

Hi,
Is it possible to perform new installation on OAM Access server in the database using manual methods (By running specific scripts). Without using GUI method to create the component databases?
The databases for the OAM will be manually created, What are the list of scripts that needs to be run against the database which are responsible for creating the "OAM-Coreid Access" component?
Does not find the informationin the installation guide.
thanks in advance.

Hi Franck,
I have found the script(rw_server.sql). I want to known who will be the owner of objects which i will create with this script.
Can you explain me this sentence:"
alternatively just uncomment the references in rp2rro.pll."
Thank you for your help.

Is there a way to create a database with Test Stand?

Anyone know of a way to have Test Stand create a database? My company standard MS Office suite is Microsoft Access 2010, and TestStand does not support the .accmdb extension type(format), so I have to create new databases using old formats. I'm worried about backwards compatability down the road since good ole Microsoft doesn't seem to care about legacy formats.
I'm still a beginner with databasing, so any suggestions would be greatly appreciated.

TestStand 2012 SP1, and we are using a modified Generic Recordset (NI). The problem we are having right now is that the Build SQL instructions are not creating the database tables the way we are configuring them from the "Statements" and "Column/Parameters" tabs under Database Options.
What is happening is when we validate the schema, and drop all schema tables, it empties all the database tables, but then when you build using the TestStand generated sql file, we get errors(shown below) we are not understanding, and we can no longer write to the database and LabVIEW throws a "Data type mismatch in criteria expression" error like this
"Possible reason(s):
ADO Error: 0x80040E07

How to Create Public database link in oracle 9i?

Friends,
OS: RHEL AS 3
DB: 9iR2
database name 1 = nubul
database name 2 = test
in the 'nubul' database server using system user.
i created a database link to connect the 'test' database
sql> create public database link test using 'test';
database link created.
then i logged in as normal user....
sql> select count(*) from employee@test
Error at line 1:
ORA-12154: TNS: could not resolve service name
where i am making mistake?
i gave the linkname as my remote database name.
am i have to make any entry in the tnsnames.ora?
thanks & regards

You have to remember that when you access a dblink, the database where the link is defined is acting as a client to the database to which the link points ... exactly the same as if you you were using sqlplus on the machine hosting the db where the link is defined. In other words, given:
Host 'Host-src', with database 'db-src', with a dblink 'lk_target'
Host 'host-trgt', with database 'db-trgt'
When you connect to db-src and access lk-target, db-src is now acting as a client to db-trgt. Exactly as if you had opened sqlplus on host-src and connected directly to db-trgt. So, given the above scenario
host-src$> sqlplus scott/tiger@db-src
sql> select * from emp@lk_target;when you execute that SELECT to the link, the same tns considerations are in effect as if you had
host-src$> sqlplus scott/tiger@db-trgtThe same tnsnames.ora entry, on the source machine, is required for both.

SSMS crash when creating new database diagram

For several years I have been unable to create database diagrams from within SSMS. I have tried every combination of VS2005, VS2008, VS2012 and VS2013 with every combination of SQL2005, SQL2008, SQL2012 and SQL2014.
I have installed, uninstalled, and repaired many dozens of times. I am currently using VS2013 ultimate with SQL2014 express.
I have tried every related 'workaround' that I can find on the internet. Still the problem persists.
Any help would be deeply appreciated.
Here are the relevant details with file versions:
In SSMS, I right-click on a database and choose New Database Diagram. A Blank diagram window appears with the SSMS error dialog:

BEST PRACTICES FOR CREATING DISCOVERER DATABASE CONNECTION -PUBLIC VS. PRIV

I have enabled SSO for Discoverer. So when you browse to http://host:port/discoverer/viewer you get prompted for your SSO
username/password. I have enabled users to create their own private
connections. I log in as portal and created a private connection. I then from
Oracle Portal create a portlet and add a discoverer worksheet using the private
connection that I created as the portal user. This works fine...users access
the portal they can see the worksheet. When they click the analyze link, the
users are prompted to enter a password for the private connection. The
following message is displayed:
The item you are requesting requires you to enter a password. This could occur because this is a private connection or
because the public connection password was invalid. Please enter the correct
password now to continue.
I originally created a public connection...and then follow the same steps from Oracle portal to create the portlet and display the
worksheet. Worksheet is displayed properly from Portal, when users click the
analyze link they are taken to Discoverer Viewer without having to enter a
password. The problem with this is that when a user browses to
http://host:port/discoverer/viewer they enter their SSO information and then
any user with an SSO account can see the public connection...very insecure!
When private connections are used, no connection information is displayed to
SSO users when logging into Discoverer Viewer.
For the very first step, when editing the Worksheet portlet from Portal, I enter the following for Database
Connections:
Publisher: I choose either the private or public connection that I created
Users Logged In: Display same data to all users using connection (Publisher's Connection)
Users Not Logged In: Do no display data
My question is what are the best practices for creating Discoverer Database
Connections.
Is there a way to create a public connection, but not display it in at http://host:port/discoverer/viewer?
Can I restrict access to http://host:port/discoverer/viewer to specific SSO users?
So overall, I want roughly 40 users to have access to my Portal Page Group. I then want to
display portlets with Discoverer worksheets. Certain worksheets I want to have
the ability to display the analyze link. When the SSO user clicks on this they
will be taken to Discoverer Viewer and prompted for no logon information. All
SSO users will see the same data...there is no need to restrict access based on
SSO username...1 database user will be set up in either the public or private
connection.

You can make it happen by creating a private connection for 40 users by capi script and when creating portlet select 2nd option in Users Logged in section. In this the portlet uses there own private connection every time user logs in.
So that it won't ask for password.
Another thing is there is an option of entering password or not in ASC in discoverer section, if your version 10.1.2.2. Let me know if you need more information

Controlfile corrupted when creating a database - ORA-00202

Hi Oracle experts,
I have two virtual machines, the clusterware installed fine and is accessing shared disks, also ASM is running fine.
When I created the database using dbca everything went fine until the very last end, I saw a window indicating that instances on both nodes were starting then I got this error for the second instance:
PRKP-1001 : Error starting instance vrac2 on node monoravpc11

In the alert there are these errors:

They are good and valid.
So, any hint? any suggestion? I am lost here, I even created a new controlfile I still received the very same message.

How to create a database link on an ms acces data source

Hello every body
Is it possible to create a database link on an MS access data source under
oracle 10 g and Apex ?
If yes how to do it ?
Thanks in advace

I don't know what Apex is!!! But try to follow these instructions.
It works for Oracle 9i.
As far as I know, you are supposed to have installed other than ORACLE Client to complete these instructions.
1. Control Panel / Administrative Tools / Data Sources (ODBC)
Folder: System DSN /
click add
Choose : Microsoft Access Driver
Data Source Name : my_test
Description : any_description_you_want
click Database/Select... : full pathname for <your_file.mdb>
click OK
Click OK
2. Goto OH\hs\admin:
2.1) Create a copy of "inithsodbc.ora" file giving it this name:
initmy_test.ora
2.2) Edit "initmy_test.ora" and change as below.
# HS init parameters
HS_FDS_CONNECT_INFO = my_test
HS_FDS_TRACE_LEVEL = OFF
3. Add this entry to listener ( Don't forget to stop/start the listener )
(SID_DESC =
(SID_NAME = my_teste)
(ORACLE_HOME = <Path to OH> ) ### Ex: D:\ORANT901
(PROGRAM = hsolesql)
4. Now you need to add entries to point to the HS in the tnsnames.ora :
access =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=<your_host>)(PORT=1521))
(CONNECT_DATA=(SID=my_test))
(HS=my_test)
5. Now you need to go into the database and create the database link:
CREATE PUBLIC DATABASE LINK "ACCESS_DB" USING 'access';
6. select * from your_table@ACCESS_DB;

How to create a database using Java?

Hi there..
I'm a student who is currently studying IT and was asked to do a project based on database but create using Java.. since i'm a beginner..i was wondering whether is it possible to do that?
and if it is possible.. can you kindly show me a sample of code on how to start the project...
thank you
yours sincerely,
Shafini

While duffymo is correct in regard to most major database products, it's my understanding (warning! wild-ass guess coming) that the Hypersonic DB is more "application-centric" and the dynamic creation of databases is part of its design. It's pure Java database software, and therefore is not appropriate for all database projects, in particular those that require extremely high-performance.
See http://hsqldb.org/
I've not used it yet (but soon though), and I can't really advise anyone about it.
However, I'm wondering if you phrased you question in a way that is confusing us. To most of us in casual conversation, a "database" is both (1) a large organized collection of data and (2) the software that is used to organize and access it. However, the phrase "create a database" usually means creating a (1) database (a collection of data) using an already created (2) database software, such as Oracle, MySQL, DB2, HSQDB, etc., etc. If you'r question is, how do a create some new database software using Java, the answer is that this is a very very big and hard thing to do for the general case and probably not something you want to be doing.

How to create a database trigger for automatic run statspack.snap

Hi,
I want to create a database trigger to run statspack.snap at startup.
connect /as sysdba
grant create any trigger to perfstat;
connect perfstat/perfstat
create or replace trigger auto_snap
after startup on database
begin
statspack.snap;
end;
after startup on database
error at line 2:
ora-01031: insufficient privileges
connect /as sysdba
create or replace trigger perfstat.auto_snap
after startup on database
begin
statspack.snap;
end;
Trigger created.
after shutdown and startup the database, the trigger has not been run. (no statspack snapshot)
What I have done wrong?

hi... I have created a database link but it is showing some error. Can you please tell me, do we have to update the details in TNSNAMES.ora file regarding the database which i am creating now before creating database link?????
awaiting for your response,
Thanks in advanceI'm sorry, but "showing some error" is NOT an actionable error message. Why do you think we can solve your error if you don't tell us what the error is?
Yes you will need to adjust your tnsnames. When a process in a database_A accesses database_B via a dblink in database_A, the database_A is acting as a client to database_B. At that point database_A is just like sqlplus or sqldeveloper, and all tns considerations are the same.

How to display result of database query in JFrame?

How to display result of oracle database query in JFrame?
This is part of my code:
String username, password;
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
OracleConnection conn = DriverManager.getConnection(String url, String username, String password);
Statement s= conn.createStatement();
ResultSet q= s.executeQuery("SELECT A, B, C FROM TABLE X");
Forget what url, username & password are. Is there any problem with my code?

How to create JTable with unknown no. of rows? How to get no. of rows of a query?
I saw the demo of creating JTable on java.sun.com but the the table has a certain no. of rows which is not applicable to my case.
Suppose the result of query is a table with 3 attributes so there are 3 columns in the table.
R contains the result of the query.
Should it be something like this if I want to create JTable of the query?
How to make n rows of {R.getString(1),R.getString(2),R.getString(3)};?
public SimpleTableDemo() {
super(new GridLayout(1,0));
String[] columnNames = {"A",
"B",
"C",
while (R.next())
// content of a row
Object[][] data = {R.getString(1),R.getString(2),R.getString(3)};
I can't run it because I still can't debug my code which is said before.
Thx!
