OC4J uses data sources to define connections to databases. When OC4J starts, it creates DataSource objects based on it's configuration information. These DataSource objects act as connection factories, and allow applications to obtain a connection without knowing the physical details of the database being used. Data sources are defined by default in the file J2EE_HOME/config/data-sources.xml. See similar questions...

A mode is not linked to a particular database. Modes can be set locally to the session (connection), or globally for the server. you can change these settings using SET [SESSION|GLOBAL] sql_mode='modes'. See similar questions...

The system we use requires some high-level programming knowledge. We use a relational database, MySQL, along with our own customized programs and storage system. You can read about our image retrieval system here: http://calphotos.berkeley.edu/retrieval.html. Our programs are freely available to other developers who want to build similar systems. The page above contains instructions on how to do that. There are several commercial image databases. See similar questions...

Developing a database connection pool is a relatively advanced project. You should consider using an existing open source tool like the Apache Commons database connection pool component. The Statement executeUpdate(String) method takes a single string argument. The string concatenation syntax you have used is incorrect and represents multiple comma separated string arguments, not a single string. See similar questions...

Look at the Enterprise JavaBeans Developers Guide and Reference. Provide the type of the elements in your Collection. With this information, OC4J generates the correct orion-ejb-jar.xml file for you. Once you have the correct orion-ejb-jar.xml file, you can use this and remove the items_type attribute from your code. See similar questions...

With Domino 1.5b3 and later, add "&Login=1" to a Domino URL. This will force the user to log in before allowing access to a database (without requiring you to set Default and Anonymous access to No Access). See similar questions...

The first step would be to upload your Access database up to the web server. We prefer that you put this in the /db directory on the same level as the /wwwroot directory but you can if desired put it in other folders inside the wwwroot directory and request we set read/write permissions on it there. Then create a support ticket at our HelpDesk with the name and location of the database file and the DSN name you would like to use so we can create a DSN for you. See similar questions...

sDSN = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=<%=server.mappath("vsproducts.mdb")%>;" Upload this file to the database folder on your web and open the page in your browser. You should see one line of text such as... Now you just need to paste this line into your db_conn_open.asp file using notepad. Make sure there are no line breaks and that all other entries in db_conn_open.asp are commented out or deleted. If you get an error that the test. See similar questions...

No. Even though system itself runs on the client computer, it relies heavily on the Internet connection. The system will be virtually unusable if a dial-up connection is used. See similar questions...

Java database programming requires some relatively complicated classpath and database-specific configuration and class loading which are explained elsewhere. This example focuses on creating and executing an SQL insert statement using a PreparedStatement, with values taken from command line parameters. It uses a fixed database driver class name, database URL, user name and password for simplicity. See similar questions...
