com.sap.dbtech.jdbcext.DataSourceSapDB Class

To connect your Java application to a database and to open a database session, you can use the com.sap.dbtech.jdbcext.DataSourceSapDB class (part of sapdbc.jar). This class implements the javax.sql.DataSource interface of the Java platform. More information: http://java.sun.com

Note Note

Alternatively, you can use the java.sql.DriverManager.getConnection method of the Java platform.

End of the note.

Prerequisites

You have started the SAP MaxDB X Server (communication server).

More information: X Server, Starting the X Server

Note that you must start X Server even if the Java application and the database are located on the same computer.
You have loaded the JDBC driver.
More information: Loading the JDBC Driver

Properties of DataSourceSapDB Objects
<property_name>	Default value	Description
`cache`	-	Specifies for which SQL statements in prepared statements the JDBC driver saves information (for example, on the used parameters) in a dedicated cache Possible values: `all`: all SQL statements Combination of the following letters `s` (SELECT statements) `i` (INSERT statements) `u` (UPDATE statements) `d` (DELETE statements) Example `cache=iud` The database system saves information on INSERT, UPDATE and DELETE statements in the cache. End of the example.
`databaseName`	-	Database name
`description`	-	Description
`loginTimeout`	30	Timeout for the logon (in seconds)
`password`	-	Password
`port`	7210	Port of the X Server on the database computer More information: X Server, Ports and Protocols of the X Server
`reconnect`	`on`	RECONNECT mode Possible values: `on`: The system automatically reconnects to the database instance after a command timeout. `off`: There is no automatic new connection.
`serverName`	`localhost`	Database computer
`sqlMode`	`INTERNAL`	SQL mode `ORACLE \| INTERNAL`
`timeout`	-	Timeout for the database session (in seconds) If you specify this connection option, you override the timeout that has been configured for the database instance with the special database parameter `SessionTimeout` (see Database Administration, Special Database Parameters).
`trace`	-	`<directory>/<jdbc_trace_file>` If you specify this connection option, then the database system writes a JDBC trace in the `<jdbc_trace_file>` file in the directory `<directory>`.
`traceSize`	-	Maximum number of lines in the JDBC trace file. If this number of lines is exceeded, the database system begins to overwrite the content of the JDBC trace file
`transport`	`socket`	Communication method for communicating with the DBM server Possible values: `socket`: TCP/IP connection `secure`: SSL connection, see Setting Up an SSL Connection
`unicode`	`false`	Unicode Support `true`: the JDBC driver sends the user name, password and SQL statements in Unicode to the database instance `false`: the JDBC driver uses ASCII
`url`	-	Connection URL
`user`	-	Name of the database user

You can also transfer most properties as connection options within the connection URL url. The following properties are exceptions: description, databasename, servername, url, port, loginTimeout.
