  The "eclipselink.jdbc.uppercase-columns" property configures native SQL queries are used, the JDBC meta-data may return column names in lower case on some platforms. If the column names are upper-case in the mappings (default) then they will not match. This setting allows for forcing the column names from the meta-data to upper-case.

  The "eclipselink.jdbc.allow-native-sql-queries" property specifies whether any user defined SQL is allowed within a persistence unit. This is of particular importance within a multitenant to minimize the potential impact of revealing multi tenant information. By default any persistence unit containing at least one multitenant entity will cause this flag to be set to "false".

  The "eclipselink.allow-zero-id" property configures if zero is considered a valid id on a new entity. If the id is not considered valid and sequencing is enabled for the entity a new value will be assigned when it is persisted to the database (INSERT). By default an id value of 0 is assumed to be null/unassigned. This allows 0 to be a valid id value. This can also be set per class using the PrimaryKey annotation and IdValidation.

• DEPLOY_ON_STARTUP

  public static final java.lang.String DEPLOY_ON_STARTUP

  The "eclipselink.deploy-on-startup" property controls whether EclipseLink creates the persistence unit when the application starts up, or when the persistence unit is first actually accessed by the application.

  Setting this to "true" causes the persistence unit to be created when the EntityManagerFactory is created, usually during deployment to a Java EE 7 container or servlet container. Enabling this option may increase startup time of the container/server, but will prevent the first request to the application from pausing while the persistence unit is deployed.

  When this property is set to "false" the persistence unit is not initialized until the first EntityManager is created or until metadata is requested from the EntityManagerFactory.

  When set to "false", there is a known issue with Fields of static metamodel classes ("Entity_" classes) being null until the persistence unit is initialized. This behaviour won't affect applications unless they use the static metamodel feature. (See bug 383199)

  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:

  • 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.

• JDBC_RESULT_SET_ACCESS_OPTIMIZATION

  public static final java.lang.String JDBC_RESULT_SET_ACCESS_OPTIMIZATION

  The "eclipselink.jdbc.result-set-access-optimization" property allows to set whether a query should by default use ResultSet Access optimization.

  The optimization allows to avoid getting objects from ResultSet if the cached object used. For instance, SELECT id, blob FROM .. with optimization would extract only "id" from ResultSet, and if there is a corresponding cached object and it's not a refresh query, "blob" would never be extracted. The draw back is keeping ResultSet and connection longer: until objects are built (or extracted from cache) for all rows and all eager references (direct and nested) for each row. Note that the optimization would not be used if it contradicts other query settings.

  Allowed Values (String):

  • "false" - don't use optimization
  • "true" - use optimization

  Default value is ObjectLevelReadQuery.isResultSetAccessOptimizedQueryDefault = false;
