Utilizing Connection Pooling in Spring Boot R2DBC In a Spring Boot application that employs blocking connection to a database like JDBC, connection pooling is commonly managed through a widely-used library known as HikariCP. Spring Boot's JdbcTemplate experiences exhaustion of connection pool ...

I've been reading material on the net about implmenting JDBC connection pooling using the MySQL connector/J 3.0. And then, JNDI came in between. I'm quite new to the J2EE domain and know nothing about JNDI usage (except basics I picked up from reading on the net). ...
What is JDBC OCI Connection Pooling? JDBC OCIConnectionPool is for pooling multiple stateful sessions with few underlying physical connections to database. The connection is bound to the session only for duration of call. The pool element is the underlying physical connection. The application sessions...
Establishing a JDBC Connection: A Beginner’s Guide JDBC, or Java Database Connectivity, is a powerful tool that allows Java applications to interact with databases. In this section, we’ll walk you through the process of establishing a JDBC connection, executing queries, and retrieving results....
Enable greater control over the number of concurrent database connections that can be in use at any time for a specific JDBC data source. Although these aims overlap with those of J2EE Java™ connection pooling, the priority is not to maximize the performance of individual...
