hikaricp

I use jpa+hibernate+hikariCP. Today I got connection closed error. I setted connectionTimeout and ideleTimeout properties(hikari). If in meantime use does not do any operition hikari close the pool connections auto. So that I got closed connection problem. My question how can I set properly hiker(jpa,hibernate) properties so if user comes back after 3-4 hours and try to do some operation hikari auto reconnect to db? is it possible? I use hikari v2.6.1 and hibernate v5.2.8.Final This should already be working. Are you holding the connection open during this time? By default HikariCP closes and

I know that, at some point between Grails 1.X and Grails 2.X, the default connection pooling library changed from commons-dbcp to tomcat-dbcp . Now, I'm trying to configure either BoneCP or HikariCP as the connection pooling library for my Grails application. However, I see that this answer offers a solution which might only apply to Grails 1.X. I also found this Gist , but again, I don't know which Grails version it applies to. So, is it possible to define a custom connection pool inside a Grails 2.3.6 application? Thanks! UPDATE: OK so you actually need to tell Grails not to pool the

I'm using HikariCP 2.4.6 and at Tomcat 8 startup, I get a warning message: 01-Aug-2016 11:18:01.599 INFO [RMI TCP Connection(4)-127.0.0.1] org.apache.catalina.core.ApplicationContext.log Initializing Spring FrameworkServlet 'Spring MVC Dispatcher Servlet' [2016-08-01 11:18:01,654] Artifact blueberry:war exploded: Artifact is deployed successfully [2016-08-01 11:18:01,655] Artifact blueberry:war exploded: Deploy took 33,985 milliseconds Aug 01 2016 11:26:52.802 AM [DEV] (HikariPool.java:614) WARN : com.zaxxer.hikari.pool.HikariPool - 9m13s102ms - Thread starvation or clock leap detected

Our site get roughly 1M pv/day, and we use Tomcat for sure. I couldn't find much information about jdbc-pool , not sure if it's stable enough for production. Anyone got experience on it? and any configuration/tuning stuff for reference? As someone mentioned, BoneCP might be another choice. But seems it's discontinued (so sad...). Would it be a better choice? btw, HikariCP is too young, I would keep an eye on it as it's the latest/fastest CP so far I found. Thanks for any advice. I'm one of the authors of HikariCP. That said, the "new" Tomcat pool is among the best we've tested. It has a lot of

Hibernate 的功能被拆分成一系列的模块/包（modules/artifacts），其目的是为了对依赖进行独立（模块化）。 模块名称 说明 hibernate-core 这个是 Hibernate 的主要（main (core)）模块。定义了 ORM 的特性和 API 以及一系列整合的 SPIs。 hibernate-envers Hibernate 历史的实体版本特性 hibernate-spatial Hibernate 的 Spatial/GIS 数据类型支持 hibernate-osgi Hibernate 支持运行 OSGi 容器 hibernate-agroal 整合 Agroal 连接池库到 Hibernate hibernate-c3p0 整合 C3P0 连接池库到 Hibernate hibernate-hikaricp 整合 HikariCP 连接池库到 Hibernate hibernate-vibur 整合 Vibur DBCP 连接池库到 Hibernate hibernate-proxool 整合 Proxool 连接池库到 Hibernate hibernate-jcache 整合 JCache 缓存特性到 Hibernate，使任何与其兼容的缓存实现能够成为 Hibernate 二级缓存的提供者 hibernate-ehcache 整合

I'm trying to use HikariCP in postgresql and I can't find anywhere the configuration for postgresql. Please point me to any example for postgresql with HikariCP or any configurations tutorial for the same. I tried to use it like below but it didn't work and then I realized it was meant for MySQL public static DataSource getDataSource() { if(datasource == null) { HikariConfig config = new HikariConfig(); config.setJdbcUrl("jdbc:mysql://localhost/test"); config.setUsername("root"); config.setPassword("password"); config.setMaximumPoolSize(10); config.setAutoCommit(false); config
