|

Hibernate is a powerful object/relational mapping tool for building Java applications. It significantly reduces repetitive persistence related programming tasks by mapping the object model's data representation to a relational data model. The mapping feature eliminates paradigm mismatch issues caused by data handling between objects and relational databases.
|
||||
Hibernate is a powerful object/relational mapping tool and a query service for building Java applications. Hibernate offers a sophisticated object-oriented HQL (Hibernate query language) allowing the programmer to make use of polymorphic queries. Queries can be expressed in native SQL or using Java-based Criteria and Example queries. However, please read these release notes for more information on software that are compatible with this version of Hibernate release.

Extract files from the Hibernate <literal>ZIP</literal> file to the desired location. Open the directory where you have extracted these files. To use Hibernate, you must configure the project's classpath settings to point to these <filename>jar</filename> files. Settings for individual IDEs differ, but normally you would add the <filename>jar</filename> files as external library files.

To use your database with Hibernate, copy your <literal>JDBC</literal> driver into the <literal>lib</literal> directory.

Additional configuration notes are available in <citetitle pubwork="book">Hibernate Reference Guide</citetitle>, chapter 3: Configuration. The Hibernate supported databases are: Oracle9i, Oracle10g, MS SQL 2005, PostgreSQL and MySQL.

All new features and bug fixes mentioned in these release notes are applicable to VERSION;.
|
||||
It is recommended that the Hibernate unit tests be executed using the same dialect and version of JDBC that will be used in production, to ensure that the configuration setting, <property>hibernate.jdbc.batch_versioned_data</property>, is set properly. The value for <property>hibernate.jdbc.batch_versioned_data</property> determines if Hibernate will use batches for updating versioned data (an optimization).
|

</para>

<section id="New_Features">
|
||||
<title>New Features</title>
|
||||
<para>
|
||||
Optimistic locking relies on the ability to obtain the number of rows updated. If the JDBC driver does not return update counts for each command in a batch, then <property>hibernate.jdbc.batch_versioned_data</property> should be set to "false".
|
||||
</para>
|
||||
<para>
|
||||
The unit tests use the settings in <filename>etc/hibernate.properties</filename>. The value for <property>hibernate.jdbc.batch_versioned_data</property> is set to <parameter>true</parameter> in that file. If the unit tests involving optimistic locking fail, then the appropriate value for this flag is <parameter>false</parameter>. Some versions of Oracle JDBC do not support returning update counts for each command in a batch, so it is particularly important to test using the same version of JDBC as will be used in production.
