Introduction In this article, I’m going to show you 9 tips that will help you speed up your Oracle database application when using JPA and Hibernate. To get the most out of the relational database in use, you need to make sure the data access layer resonates with the underlying database system, so, in this article, I’m going to present you several tips that can boost up the performance of your Oracle, JPA and Hibernate applications.
Hibernate Application Performance Tuning
Introduction Because performance tuning is very important when it comes to developing a data access layer, in this article, I’m going to show you how you can optimize the famous Hibernate Caveat Emptor application using Hypersistence Optimizer. The Caveat Emptor application was created by Christian Bauer and Gavin King for the Hibernate in Action book they published in 2004 and was included in both the first and second editions of the well-known Java Persistence with Hibernate book.
Use Hibernate Dynamic Update for JSON properties
Introduction In this article, I’m going to explain why you should always use the Hibernate Dynamic Update feature for entities that map JSON properties. Since Hibernate ORM does not offer support for JSON column types, we are going to use the Hypersistence Utils library, which provides a JsonType that allows you to map String, Map, List, JsonNode, Java Records, or POJOs on JSON columns, no matter if you are using PostgreSQL, MySQL, Oracle, SQL Server, or H2.
20 years of Hibernate
Introduction 20 years of Hibernate and counting. On the 23rd of May 2001, Gavin King launched the first version of Hibernate. Twenty years later, Hibernate is one the most successful Java data access frameworks, having millions of developers using it on a per-daily basis.

Introduction In this article, I’m going to explain what the JPA Default Fetch Plan is and how it differs from the Query Fetch Plan when using FetchType EAGER associations.
Connection Monitoring with JPA and Hibernate

Maven and Gradle Hibernate Enhance Plugin
Introduction In this article, I’m going to explain how the configure the Maven and Gradle Hibernate Enhance Plugin. The goal of the Hibernate Enhance plugin is to instrument the JPA entity bytecode in order to improve the effectiveness and efficiency of the associated data access operations.
