[HTML DB] How to use the existing database table?

[HTML DB] How to use the existing database table?
I installed Oracle 10g database in Computer A(Windows 2000), and I already create all the tables with data and the data size is about 300MB.
In Computer B(Windows 2000), I installed HTML DB 1.6.
How can I use /get the existing database table (in computer A) for HTML DB?
Could anyone help me on this? I am newbie and I need some detail instructions. or Where can I find the examples.....
Thanks

Well I guess if you wish to retain that architecture, i.e. HTMLDB on one machine and your data on another, you will have to establish database links to access the data. Oracle documentation will describe how to achieve that.

How to use the default database service name on creating procedure for data

how to use the default database service name on creating procedure for datagaurd client failover ??? all oracle doc says create a new service as below and enable at DB startup. but our client is using/wanted database default service to connect from application on the datagaurd environment (rac to non rac setup).please help.
Db name is = prod.
exec DBMS_SERVICE.CREATE_SERVICE (service_name => 'prod',network_name =>'prod',failover_method => 'BASIC',failover_type => 'SELECT',failover_retries => 180,failover_delay => 1);
says already the service available.
CREATE OR REPLACE TRIGGER manage_dgservice after startup on database DECLARE role
VARCHAR(30);BEGIN SELECT DATABASE_ROLE INTO role FROM V$DATABASE;
IF role = 'NO' THEN DBMS_SERVICE.START_SERVICE('prod');
END IF;
END;
says trigger created, but during a swithover still the service is listeneing on listener.
tns entry.
prod =
(DESCRIPTION =
(ADDRESS_LIST =
(LOAD_BALANCE = YES)
(ADDRESS = (PROTOCOL = TCP)(HOST = prod1)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = prod2)(PORT = 1521)) ---> primary db entry
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = proddr)(PORT = 1521)) --> DR DB entry
(CONNECT_DATA =
(SERVICE_NAME = prod)
thanks in advance.

Hello;
So in the example below replace "ernie" with the alias you want the client to use.
I can show you how I do it :
First an entry need to be added to the client tnsnames.ora that uses a SERVICE_NAME instead of a SID.
ernie =
(DESCRIPTION =
    (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP)(HOST = Primary.host)(PORT = 1521))
       (ADDRESS = (PROTOCOL = TCP)(HOST = Standby.host)(PORT = 1521))
       (CONNECT_DATA =
       (SERVICE_NAME = ernie)
)Next the service 'ernie' needs to be created manually on the primary database.
BEGIN
   DBMS_SERVICE.CREATE_SERVICE('ernie','ernie');
END;
/After creating the service needs to be manually started.
BEGIN
   DBMS_SERVICE.START_SERVICE('ernie');
END;
/Several of the default parameters can now be set for 'ernie'.
BEGIN
   DBMS_SERVICE.MODIFY_SERVICE
   ('ernie',
   FAILOVER_METHOD => 'BASIC',
   FAILOVER_TYPE => 'SELECT',
   FAILOVER_RETRIES => 200,
   FAILOVER_DELAY => 1);
END;
/Finally a database STARTUP trigger should be created to ensures that this service is only offered if the database is primary.
CREATE TRIGGER CHECK_ERNIE_START AFTER STARTUP ON DATABASE
DECLARE
V_ROLE VARCHAR(30);
BEGIN
SELECT DATABASE_ROLE INTO V_ROLE FROM V$DATABASE;
IF V_ROLE = 'PRIMARY' THEN
DBMS_SERVICE.START_SERVICE('ernie');
ELSE
DBMS_SERVICE.STOP_SERVICE('ernie');
END IF;
END;
/lsnrctl status - should show the new service.
When I do this the Database will still register with the listener. I don't give that to the clients. That one will still be available but nobody knows about it. Meanwhile "ernie" moves with the database role.
So in my example the default just hangs out in the background.

How to use your own database with your users to authenticate in a Web app?

Hello, everybody!
I'm starting to write my first web application and I'm going to use JSF, JPA and EJB3 in this application. One of the first things that I have to do on it is the authentication part where I'll have a page with a user name and a password for the user to login. So, as I'm new to all this in Java (I've already implemented this on .NET in the past), I was studying the Java EE 5 Tutorial, especifically the section "Example: Using Form-Based Authentication with a JSP Page". But I saw that the users that the sample application uses come from the file realm on the Application Server. The users are created there and assigned a name, a password and a group. After the users are in the Application Server we can simply uses forms authentication declaratively in the deployment descriptor (web.xml).
But the problem is that this doesn't work to me as I already have my own database with my users, so I want to use it instead of having to create the users on the Application Server.
So, I'm asking you how to do that. Of course I'm not expecting that you place the code here to me as I know that such a thing could be complicated. Instead, I'm asking if you know about some tutorial, article, book or something that teaches how to do what I want. But I would like to see theses examples using JSF and/or EJB3 because these are the technologies that I'm using to develop. It's a pity that the Java EE 5 Tutorial doesn't have an example using a custom database as I know that this situation is very common in the majority of web sites.
Thank you very much.
Marcos

From memory, it goes like this... You just create a
raw jdbc connection on your user database using a
special "login" DB user account, which has
permissions only to an "authenticate" stored query,
which accepts two arguments: username & password, and
returns a boolean 0 or 1 rows found.When I implemented this in .NET's ASP.NET I had the same solution. I had an special user created in the database that I used to log in. When the real user entered his username and password I was already logged in and I had just to check his username and password agains the right table in my database.
But that was only possible bacause when I connected to the database using my hidden user, I used the rights APIs in ASP.NET that coordinate the authentication process. This means that before login in, no one could access any resources (pages, atc...). So what I'm saying is that I can't manager this manually in Java. Java has to have some API or whatever to allow me to control the login process programmatically, while letting the Application Server control the access to the resources.

How to use OWN logical database

Hi all,
hope somebody can help me.
I copied a standard logical database (FPMF). The program which I use and have modified is also copied from standard.
How can I assure that the program use MY logical database instead of the SAP-One?
In my case I have some get statements. And these get statements all refer to FPMF and not to my copied database.
Do anybody what's the probelm?
Cheers
Philip

Yes, I know. And I am not happy with this solution.
But I didn't see another way for my issue.
Thank you very much.

How to use the JE database with other data types than byte arrays?

Hi! I searched the javadoc of Berkley DB JE, for a way to introduce entry (but I need also retrieve) data with other type than byte arrays, e.g. String, or anything else, as int may be, etc.
Still, I didn't find any such way, because the main (only?!) method to entry data into an open database - according what I found in javadoc - is:
"public OperationStatus put(Transaction txn, DatabaseEntry key, DatabaseEntry data) throws DatabaseException"
and both this and the corresponding method for retrieves, are based on the same DatabaseEntry type, which allow only entry data on byte[] support.
What if I need to use Strings or int, or even char? I must do a special conversion from these types, to byte[], to use the database?
Thank you!

On the doc page (this is also in the download package),
http://download.oracle.com/docs/cd/E17277_02/html/index.html
see:
Getting Started Guide
Java Collections Tutorial
Direct Persistence Layer (DPL)
All of these describe how to use data types other than byte arrays.

How to use the backup database to create report or update testing

Hi,
I have a fully backup of production database in the last month, and I have using Oracle 8.1.7. I want to known how can I use

How to use Forms Default Database Connection in java class

When a form based application is started, a connection is made with underlying database. This is the Default (Primay) Database Connection.
The problem is I have some of my business logic implemented in a java class. In this class I have to make a another connection with the same database. What I want to do is to use the original Database Connection in the java class. In this I may avoid the overhead of reconnection.
Could anyone pls guide me in this way...

you can't share the forms connection. Sorry :(

How to use a custom database authentication with APEX_AUTHENTICATION??

i have Custom user authentication method.
create or replace function user_check(username varchar2,password varchar2) return boolem
is
check_out integer;
begin
select count(*) into check_out from "user" where USER_EMAIL=username and USER_PASS=password;
if check_out >0 then
return true;
else
return false;
end if;
end;
apex_authentication.login() how to use. And how to make apex_authentication.login() use my method Verify User Login

You can't mix custom authentication and the internal APEX authentication functions.. So either you use the pre-built user authentication in APEX or you can build your own CUSTOM authentication...
Many examples of custom authentication are out there...
Thank you,

How to use non-MySQL database with DW and PHP...???

I need to connect to a data-source that is not MySQL from
with my PHP scripts. The only option I get under the Databases tab
in the Application panel is MySQL Connection. What about just
standard ODBC connections? Will DW not handle those for me? Do I
have to do all of that by hand??
Any information would be greatly appreciated. Thanks!

There once existed an opensource servermodel called phakt
that used the
ADODB database abstraction library,
the company that created and supported it was bought by Adobe
and
subsequently the project was cancelled.
A group of people (including me) started a community
initiative@
http://openphakt.sourceforge.net
to continue distribution and development of
phakt, but unfortunately I don't have access to Dreamweaver
CS3 due to lack
of funding.
Phakt will almost certainly NOT run on CS3 in it's current
state, but is
should support previous versions.

How to use EBS R12 Database (10.2.0.2) for report analysis tools?

Hi All,
My client wants to use reporting tools for bussiness analysis.For this I want to use a separate database which will be replica of production database.Is there any way to achieve this in R12 database(10.2.0.2)?
Kindly share your experience.

As Srini states, knowing more about your requirements would help us to help you. :-)
Do you need a daily twice/daily snapshot of your data? If so, then you might be able to implement the solution that Srini mentioned earlier. An added benefit of this method is that it can go beyond the creation of a reporting database: it can also be leveraged in the creation of additional clones for test and dev environments.
Do you need real-time replication of data to your reporting database? If so, then you might want to investigate Oracle Streams/Goldengate (disclaimer: I'm typing on the fly, so I'm not 100% certain that this is supported).
If you're willing to license more Oracle software to solve your problem, you might also consider Oracle Business Intelligence Applications, which has out-of-the-box integration with E-Business Suite for common reporting/business intelligence needs. There are additional costs involved, but you can weigh those against the development costs of "rolling your own" MVs and reports, and maintaining them.
Again, knowing your requirements, constraints, and points of flexibility will go a long way toward figuring out which option best suits you. :)

SDF files are used by Microsoft SQL Server Compact Edition. SQL CE is not supported for Windows Store Apps/Universal Apps. Only WP Silverlight Apps can use SQL CE. You will have to switch to a different database format.
As far as I know the only DB currently supported for local deployment with Windows Store Apps is SQLite.
This article gives an introduction on how to get started with SQLite in Universal Apps:
