To create a data source for an Oracle database, you create a managed datasource. You can create a managed data source using the Application Server Control Console (see "Using Application Server Control Console") or deployment XML (see "Using Deployment XML").
For more information, see the following:
"Data Sources" in the Oracle Containers for J2EE Services Guide
You can use Application Server Control Console to create a managed data source dynamically without restarting OC4J.
For more information, see http://www.oracle.com/technology/tech/java/oc4j/1013/how_to/index.html
.
You can configure a managed data source for an Oracle database by configuring a connection-pool
element and managed-data-source
element in the data-sources.xml
file, as Example 20-1 shows.
Example 20-1 data-sources.xml For an Oracle JDBC Data Source
<connection-pool name="ScottConnectionPool"> <connection-factory factory-class="oracle.jdbc.pool.OracleDataSource" user="scott" password="tiger" url="jdbc:oracle:thin:@//localhost:1521/ORCL" > </connection-factory> </connection-pool> <managed-data-source name="OracleManagedDS" jndi-name="jdbc/OracleDS" connection-pool-name="ScottConnectionPool" tx-level="global" />
Be sure to specify a service-based connection URL in the connection-factory
element (see "How do you Define a Connection URL in OC4J?").
By default, a managed data source supports global (two-phase commit) transactions. To configure a managed data source to support only local transactions, set the managed-data-source
attribute tx-level
to local
. For more information, see "What Transaction Types do Data Sources Support?").
For more information, see the following:

If you configure a managed data source using this method, you must restart OC4J to apply your changes. Alternatively, you can use Application Server Control Console to create a data source dynamically without restarting OC4J (see Using Application Server Control Console)
