Connection connection = DriverManager.getConnection(jdbcUrl, p); connection.setNetworkTimeout(Executors.newSingleThreadExecutor(), Integer.valueOf(timeout));returnconnection; } I do not want to add a connection pool solution to my simple app, only pure JDBC can be enough for me. What I missed...
本文将特别介绍 Oracle Universal Connection Pool (UCP) for JDBC,它提供了适用于缓存 JDBC 连接的全功能连接池实现。最后,本文将讨论如何通过使用语句池获益,需要利用特定于 Oracle 的 JDBC 驱动程序的特性以及新的 JDBC 4.0 方法,这些方法已添加到 Statement 接口并且在支持 Java 开发工具包 (JDK) 1.6 及更高版...

I can't find a configuration for Oracle that doesn't result in very high timeout polling CPU usage. I tried setting a very large value, also zero (which the implementation converts to Integer.MAX_VALUE). In all cases it idles with extrem...
validationTimeout: ConnectionValidationTimeout HikariCP 属性没有相同的 UCP 属性可匹配,但有其他机制,如驱动程序属性或 UCPAPI autoCommit 使用 Oracle JDBC 驱动程序连接属性 autoCommit。 registerMbeans UCP 始终尝试注册。 threadFactory UCP 支持 setTaskManager(仅 setter API)。
This interface defines the Oracle extensions to the standard JDBC interface java.sql.Connection. You can use java.sql.Connection in your application where you do not make use of the Oracle extensions. However, when your application uses the Oracle extensions to java.sql.Connection you must use ...
Setting it to false will disable the load balancing. The default value is true. Parameters: loadBalance - Returns: oracleConnectionBuilder connectTimeout OracleConnectionStringBuilder connectTimeout(int connectTimeout) Used to configure the value of CONNECT_TIMEOUT in the DESCRIPTION node. This ...
handed the connection to the database. This would indicate an issue with a firewall where a maximum idle time setting is in place. The connection would not necessarily be "idle". This issue can arise during a long running query or when using JDBC Thin connection pooling. ...
