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 performance tuning tips
Introduction In this article, I’m going to summarise the most common Hibernate performance tuning tips that can help you speed up your data access layer. While getting started with JPA and Hibernate is fairly easy, if you want to get the most out of your data access layer, it’s very important to understand how the JPA provider works, as well as the configuration properties that can help you optimize application performance.
9 High-Performance Tips when using PostgreSQL with JPA and Hibernate
Introduction 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. In this article, we are going to see what you can do to boost up performance when using PostgreSQL with JPA and Hibernate.
9 High-Performance Tips when using MySQL with JPA and Hibernate
Introduction Although there is an SQL Standard, every relational database is ultimately unique, and you need to adjust your data access layer so that you get the most out of the relational database in use. In this article, we are going to see what you can do to boost up performance when using MySQL with JPA and Hibernate.
How to optimize the merge operation using update while batching with JPA and Hibernate
Introduction One of my readers has recently asked me about optimizing the merge entity state transition, and, because this is a great question, I decided to turn it into a blog post. In this article, you are going to see a shortcoming of the merge entity state transition and how you can deal with it using Hibernate.
The best way to map a @OneToOne relationship with JPA and Hibernate
Introduction In this article, we are going to learn the best way to map a OneToOne association with JPA and Hibernate. While there are many ways you can map a one-to-one relationship with Hibernate, I’m going to demonstrate which mapping is the most efficient one from a database perspective.
How do persist and merge work in JPA
Introduction In this article, I’m going to explain how the persist and merge entity operations work when using JPA and Hibernate. When using JPA, entity state transitions are translated automatically to SQL statements. This post is going to explain when to use persist and when to use merge.
The best way to detect database connection leaks
Introduction Database connections are not free, and that’s the reason for using a connection pooling solution in the first place. However, the connection pool alone does not solve every issue associated to managing database connections. The application developer must make sure that every Connection is closed when no longer needed. Behind the scenes, the connection pool gives a logical transaction which, when being closed, it returns back to the pool so that it can be further reused by other concurrent transactions. A connection leak happens when a connection is acquired without ever… Read More
