public class OracleDataSource extends Object implements OracleDataSource, oracle.jdbc.replay.internal.OracleDataSource, Serializable, Referenceable, oracle.jdbc.internal.Monitor
A
DataSource
object is a factory forConnection
objects. An object that implements theDataSource
interface will typically be registered with a JNDI service provider. A JDBC driver that is accessed via theDataSource
API does not automatically register itself with theDriverManager
.This data Source supports Application Continuity (AC) and transparent JDBC operation replay upon a failover. To disable such feature, set
"oracle.jdbc.enableACSupport"
to false either as a Java system property, or as a connection property on this data source.The following example illustrates the use of this data source to create a JDBC connection:
oracle.jdbc.datasource.OracleDataSource ods = new oracle.jdbc.datasource.impl.OracleDataSource(); ods.setURL("jdbc:oracle:thin:@//dbhost:dbport/dbservice"); ods.setUser("User"); ods.setPassword("Passwd"); ods.setConnectionProperty("connProp1", "value1"); ods.setConnectionProperty("connProp2", "value2"); Connection conn = ods.getConnection();
The following example illustrates the use of a connection obtained from this data source for Application Continuity protection:
oracle.jdbc.OracleConnection conn = (oracle.jdbc.OracleConnection) ods.getConnection(); conn.beginRequest(); ...... // JDBC calls protected by AC conn.endRequest();

setSSLContext
public final void setSSLContext(SSLContext sslContext)
Description copied from interface:OracleCommonDataSource
Specifies aSSLContext
to use as a factory for SSLEngine objects that carry out the TLS protocol.The SSLContext must be initialized before establishing a connection to the data source. The certificates specified by that initialization will be used in place of any connection properties that would otherwise have specified certificates, such as key store and trust store property values.
Specifying a null value will clear any non-null value that may have been set previously, causing this data source to behave as if this method had never been called at all.
- Specified by:
setSSLContext
in interfaceOracleCommonDataSource
- Parameters:
sslContext
- An SSLContext to use as an SSLEngine factory.

setTokenSupplier
public final void setTokenSupplier(java.util.function.Supplier<? extends AccessToken> tokenSupplier)
Description copied from interface:OracleCommonDataSource
Sets a supplier function that generates an access token when creating a connection with this
DataSource
. The supplier function is invoked each time thisDataSource
creates a connection. Instances ofAccessToken
that are output by the supplier must represent a token type that is supported by Oracle Database for client authentication. The supplier must be thread safe.It is invalid to configure this
DataSource
with both a token supplier and with a user name or password. If invocations ofOracleCommonDataSource.setUser(String)
,OracleCommonDataSource.setPassword(String)
,OracleCommonDataSource.setConnectionProperties(java.util.Properties)
, orOracleCommonDataSource.setConnectionProperty(String, String)
have configured thisDataSource
with a user name or password, and an invocation of this method has also configured a token supplier, then aSQLException
indicating an invalid configuration is thrown when creating a connection with this datasource.Note that
AccessToken.createJsonWebTokenCache(Supplier)
can be called to create a thread safeSupplier
that caches tokens from a user definedSupplier
.- Specified by:
setTokenSupplier
in interfaceOracleCommonDataSource
- Parameters:
tokenSupplier
- Token supplying function. Notnull
.
