Class PersistenceUnitProperties

java.lang.Object
  org.eclipse.persistence.config.PersistenceUnitProperties

public class PersistenceUnitProperties
extends java.lang.Object

The class defines EclipseLink persistence unit property names. These values are used to assist in the configuration of properties passed to Persistence.createEntityManagerFactory(String, Map) which override the values specified in the persistence.xml file.

Usage Example: Map props = new HashMap();

props.put(PersistenceUnitProperties.JDBC_USER, "user-name");
props.put(PersistenceUnitProperties.JDBC_PASSWORD, "password");

EntityManagerFactory emf = Persistence.createENtityManagerFactory("pu-name", props);

Property values are usually case-insensitive with some common sense exceptions, for instance class names.

PERSISTENCE_CONTEXT_CLOSE_ON_COMMIT

public static final java.lang.String PERSISTENCE_CONTEXT_CLOSE_ON_COMMIT

The "eclipselink.persistence-context.close-on-commit" property specifies that the EntityManager will be closed or not used after commit (not extended). In general this is normally always the case for a container managed EntityManager, and common for application managed. This can be used to avoid additional performance overhead of resuming the persistence context after a commit(). The property set in persistence.xml or passed to createEntityManagerFactory affects all EntityManagers created by the factory. Alternatively, to apply the property only to some EntityManagers pass it to createEntityManager method.

Values (case insensitive):

• "false" (DEFAULT)
• "true"

Constant Field Values

PERSISTENCE_CONTEXT_PERSIST_ON_COMMIT

public static final java.lang.String PERSISTENCE_CONTEXT_PERSIST_ON_COMMIT

The "eclipselink.persistence-context.persist-on-commit" property specifies that the EntityManager will search all managed objects and persist any related non-managed new objects that are cascade persist. This can be used to avoid the cost of performing this search if persist is always used for new objects. The property set in persistence.xml or passed to createEntityManagerFactory affects all EntityManagers created by the factory. Alternatively, to apply the property only to some EntityManagers pass it to createEntityManager method.

Values (case insensitive):

• "true" (DEFAULT)
• "false"

Constant Field Values

PERSISTENCE_CONTEXT_COMMIT_WITHOUT_PERSIST_RULES

public static final java.lang.String PERSISTENCE_CONTEXT_COMMIT_WITHOUT_PERSIST_RULES

The "eclipselink.persistence-context.commit-without-persist-rules" property specifies that the EntityManager will search all managed objects and persist any related non-managed new objects that are found ignoring any absence of CascadeType.PERSIST settings. Also the Entity life-cycle Persist operation will not be cascaded to related entities. This setting replicates the traditional EclipseLink native functionality.

Values (case insensitive):

• "false" (DEFAULT)
• "true"

See Also:

Constant Field Values

PERSISTENCE_CONTEXT_FLUSH_MODE

public static final java.lang.String PERSISTENCE_CONTEXT_FLUSH_MODE

The "eclipselink.persistence-context.flush-mode property configures the EntityManager FlushMode to be set as a persistence property. This can be set to either "AUTO" or "COMMIT". By default the flush mode is AUTO, which requires an automatic flush before all query execution. This can be used to avoid any flushing until commit. The property set in persistence.xml or passed to createEntityManagerFactory affects all EntityManagers created by the factory. Alternatively, to apply the property only to some EntityManagers pass it to createEntityManager method.

See Also:

EntityManager.setFlushMode(javax.persistence.FlushModeType), FlushModeType, Constant Field Values

ORACLE_PROXY_TYPE

public static final java.lang.String ORACLE_PROXY_TYPE

The "eclipselink.oracle.proxy-type" property is used to specify proxy type that should be passed to OracleConnection.openProxySession method. Requires Oracle JDBC version 10.1.0.2 or later. Requires Oracle9Platform or later as a database platform (TARGET_DATABASE property value should be TargetDatabase.Oracle9 or later).

Values:

• oracle.jdbc.OracleConnection.PROXYTYPE_USER_NAME,
• oracle.jdbc.OracleConnection.PROXYTYPE_DISTINGUISHED_NAME,
• oracle.jdbc.OracleConnection.PROXYTYPE_CERTIFICATE.

Property values corresponding to the specified type should be also provided:

• oracle.jdbc.OracleConnection.PROXY_USER_NAME,
• oracle.jdbc.OracleConnection.PROXY_DISTINGUISHED_NAME,
• oracle.jdbc.OracleConnection.PROXY_CERTIFICATE.

  Typically these properties should be set into EntityManager (either through createEntityManager method or using proprietary setProperties method on EntityManagerImpl) - that causes EntityManager to use proxy connection for writing and reading inside transaction. If proxy-type and the corresponding proxy property set into EntityManagerFactory then all connections created by the factory will be proxy connections.

  Constant Field Values

COORDINATION_PROTOCOL

public static final java.lang.String COORDINATION_PROTOCOL

The "eclipselink.cache.coordination.protocol" property configures cache coordination for a clustered environment. This needs to be set on every persistence unit/session in the cluster.

public static final java.lang.String COORDINATION_RMI_PACKET_TIME_TO_LIVE

The "eclipselink.cache.coordination.rmi.packet-time-to-live" property configures cache coordination for a clustered environment. Only used for RMI coordination. Sets the multicast socket packet time to live. The multicast group is used to find other members of the cluster. Set the number of hops the data packets of the session announcement will take before expiring. The default is 2, a hub and an interface card to prevent the data packets from leaving the local network. Note that if sessions are hosted on different LANs that are part of WAN, the announcement sending by one session may not reach other sessions.
