Installing and Running the Oracle Connection Manager Write the connection string that targets the Connection Manager. Using the Oracle Connection Manager requires two steps: Use a signed applet to connect to the database directly.įigure 6-1 Applet, Connection Manager, and Database Relationshipĭescription of "Figure 6-1 Applet, Connection Manager, and Database Relationship " There are two possible ways to make your application work with this important security restriction:Ĭonnect to the database by using the Oracle Connection Manager. Usually, your applet connects to a database on a host other than the one on which the Web server runs. You seldom find both servers running on the same computer. However, a Web server and database server both require many resources. If you use the TNS keyword-value pair to specify the connection information to the JDBC Thin driver, then you must declare the protocol as TCP. String connString = ods = new OracleDataSource()

You can provide it in the form of host:port:sid or in the form of a TNS keyword-value syntax.įor example, if the database to which you want to connect resides on host prodHost, at port 1521, and SID ORCL, and you want to connect with user name scott with password tiger, then use either of the two following connect strings: You can connect to the database as you would from an application.Īs with connecting from an application, there are two ways in which you can specify the connection information to the driver. If your database and Web server are running on the same host, then there is no issue and no special steps are required. This means that without these steps, your applet can connect only to a database that is running on the same host as the Web server. This is the host on which the Web server is running. Because of applet security restrictions, unless particular steps are taken, an applet can open TCP/IP sockets only to the host from which it was downloaded.
Oracle jdbc thin client connection driver#
The most common task of an applet using the JDBC driver is to connect to and query a database.
Typically, on the server side, this driver is used to access the Oracle Database from a Java stored procedure on the database.Ĭonnect ing to the Database through the Applet On the server side, this driver is used to access a remote Oracle Database instance or another session on the same database.
On the client side, you use this driver to access application servers, from a Java method to access data on Oracle Database, and to access applets. The JDBC Thin driver can be used on both client side and server side.
The Oracle Net protocol runs over TCP/IP only. Both of these protocols are lightweight implementation versions of their counterparts on the server.
The driver allows a direct connection to the database by providing an implementation of TCP/IP that implements Oracle Net and TTC on top of Java sockets. It can be used for application servers as well as for applets. The JDBC Thin driver communicates with the server using TTC, a protocol developed by Oracle to access data from Oracle Database.

Also, this driver does not require any additional Oracle software on the client side. The JDBC Thin driver is written entirely in Java, and therefore, it is platform-independent. It provides high performance, comparable to the performance provided by JDBC Oracle Call Interface (OCI) driver. The JDBC Thin Client is a pure Java, Type IV driver.
