hikaricp

问题 I have done the same, as some blogs have suggested. But still I couldn't able to solve the issue. Environment: spring - 4.2.5.RELEASE spring boot - 1.3.3.RELEASE hikariCP - 2.4.7 @Bean(name="HikariDataSource",destroyMethod = "shutdown") public DataSource dataSource2() { HikariConfig config = new HikariConfig(); config.setDriverClassName("oracle.jdbc.OracleDriver"); config.setJdbcUrl(""); config.setUsername(""); config.setPassword(""); config.addDataSourceProperty("cachePrepStmts", "true");

问题 While reading from database the logs in my dao class shows junk characters in place of unicode characters. Sql developer shows correct values from oracle database also correct NLS language encoding is set on the database. Below code works for standard jdbc: connection = DriverManager.getConnection( "jdbc:oracle:thin:@localhost:1521:xe", "adminuser", "oracle"); Statement st=connection.createStatement(); ResultSet res=st.executeQuery("SELECT menu_item_name from pending_menu_item where menu_item

问题 Im having problem accessing db, when using hikaricp this is my reference.conf play { modules { enabled += "play.api.db.DBModule" enabled += "play.api.db.HikariCPModule" } # Database configuration db { # The name of the configuration item from which to read database config. # So, if set to db, means that db.default is where the configuration for the # database named default is found. config = "db" # The name of the default database, used when no database name is explicitly # specified. default

问题 Like we can get the number of busy connection in c3p0 by using method like dataSource.getNumBusyConnections() , the same way how can we do that in case of hikaricp? Can anyone provide all the related methods between c3p0 and hikaricp? Also what is the destroy (in c3p0) method equivalent in hikaricp? 回答1: Re: connections, see these wiki pages: JMX Monitoring (via console and programatically Using Codahale/Dropwizard Metrics HikariDataSource supports both close() and shutdown() methods, they

问题 This query on an audit trail table starts slowing down once the load increases in performance testing (reads and inserts) and I've done what I can with indexing. With this query and these tables and indexes, what more can I do? CREATE TABLE [dbo].[mod2] ( [id] [int] IDENTITY, [userId] [int] NOT NULL, [epochTime] [bigint] NOT NULL, [forecastId] [int] NOT NULL, [description] [char](12) NOT NULL, [auxText] [text] NULL, [auxDate] [date] NULL ); ALTER TABLE [dbo].[mod2] ADD CONSTRAINT PK_mod2

问题 This question already has answers here : Why am I getting a NoClassDefFoundError in Java? (23 answers) Closed 2 years ago . I'm so noob at external stuff to Bukkit programming, so I'm sorry if it's so easy to solve :P I have a problem, and it's that when I try to use HikariCP in my project, it returns in an error (the title one). I'm using it in a BungeeCord plugin. The weird thing is that I have done this successfully couples of times, and I don't know why it isn't working this time. The

问题 I am having trouble recovering from a broken database connection. My test case uses the following libraries. guice-persist 4.0 Hibernate core 4.3.1 HikariCP-java6-2.3.9 (connection pool). My test runs a simple read in a loop with a small sleep between each read. @com.google.inject.persist.Transactional protected void simpleRead() { dao = new MyDao(....) dao.findBy(...) } The Dao acquires its entityManager like this @Inject protected com.google.inject.Provider<EntityManager> entityManager; The

问题 I'm using Kotlin with HikariCP and jOOQ to query my database. I've come to realize that this code works as expected, fetching the rows and closing the connection afterwards: class CountriesService(private val datasource: DataSource) { private val countries = Countries() fun getCountries(): List<String> { DSL.using(datasource, SQLDialect.POSTGRES_10) .use { ctx -> ctx.select(countries.CO_NAME) .from(countries) .orderBy(countries.CO_NAME) .fetch() return emptyList() } } } whereas if I use

问题 We are using PgBouncer as the middle ware for connection pooling for our spring-based application. Within the application, we are using HikariCP for application-level connection pooling. We have set maxLifeTime value equal to one hour for HikariCP and idleTimeOut is set to 30 seconds. I have observed that we are getting this error when app get a request after a long idle time: Caused by: org.postgresql.util.PSQLException: Connection attempt timed out. at org.postgresql.Driver$ConnectThread

问题 i am using hibernate spatial 4.3.2 along with hibernate 4.3.11 and my db is oracle 12c. I use hikariCP for connection pool. when I use hikacriCP I get an error that seems that cause is hibernate spatial can not access to the wrapped connection of hikari connection instance, this is my exception: problem is hibernate throws error when saving an entity that contains geometry field. Couldn't get at the OracleSpatial Connection object from the PreparedStatement when I remove hikari, everything is
