How does aggressive connection release work in Hibernate

Hibernate connection providers Hibernate needs to operate both in Java EE and stand-alone environments, and the database connectivity configuration can be done either declaratively or programmatically. To accommodate JDBC Driver connections as well as RESOURCE_LOCAL and JTA DataSource configurations, Hibernate defines its own connection factory abstraction, represented by the org.hibernate.engine.jdbc.connections.spi.ConnectionProvider interface.

High-Performance Java Persistence – Part One

The journey Four months, one week and two days and 114 pages; that’s how much it took to write the first part of the High-Performance Java Persistence book. As previously stated, the book is developed in an Agile fashion. Each part represents a milestone, which is accompanied by a release. This way, the readers can get access to the book content prior to finishing the whole book (which might take a year or so).

A beginner’s guide to read and write skew phenomena

Introduction In my article about ACID and database transactions, I introduced the three phenomena described by the SQL standard: dirty read non-repeatable read phantom read While these are good to differentiate the four isolation levels (Read Uncommitted, Read Committed, Repeatable Read and Serializable), in reality, there are more phenomena to take into consideration as well. The 1995 paper (A Critique of ANSI SQL Isolation Levels) introduces the other phenomena that are omitted from the standard specification. In my High-Performance Java Persistence book, I decided to insist on the Transaction chapter as it… Read More

Why you should always use connection pooling with Oracle XE

Introduction Oracle Express Edition is the free version of Oracle Enterprise Edition and its smaller size makes it very convenient for testing various Oracle functionalities. According to Oracle documentation, the Express Edition can use at most one CPU and 1 GB of RAM, but in reality, there are other limitations that are not always obvious.

The High-Performance Java Persistence book

A book in the making It’s been a year since I started the quest for a highly-effective Data Knowledge Stack and the Hibernate Master Class contains over fifty articles already. Now that I covered many aspects of database transactions, JDBC and Java Persistence, it’s time to assemble all the pieces together into the High-Performance Java Persistence book.
