A few weeks ago I began using JDBC to establish a connection to my mysql database and send queries. However, I noticed that it slowed down my Java application so I started reading about connection pooling. I decided to use c3p0 to establish my connection pool. This is the cod...
config.setJdbcUrl("jdbc:mysql://"+Settings.MYSQL_HOSTNAME+"/"+Settings.MYSQL_DATABASE+"?autoReconnectForPools=true" ); config.setUsername(Settings.MYSQL_USERNAME); config.setPassword(Settings.MYSQL_PASSWORD); config.setMinConnectionsPerPartition(5); config.setMaxConnectionsPerPartition(10); config...

Note:Connection pooling is supported only on the Java 2 SDK, v 1.4.1, and later releases. TheConnection Creationsection described when connections are created. It described how severalContextinstances can share the same connection. In this type of sharing, operations from the differentContextinstance...

An application programmer does not use the PooledConnection interface directly; rather, it is used by a middle tier infrastructure that manages the pooling of connections. When an application calls the method DataSource.getConnection, it gets back a Connection object. If connection pooling is being...
If connection pooling is being done, that Connection object is actually a handle to a PooledConnection object, which is a physical connection. The connection pool manager, typically the application server, maintains a pool of PooledConnection objects. If there is a PooledConnection object ...

Avoiding Bugs In Earlier Releases Prior to Android 2.2 (Froyo), this class had some frustrating bugs. In particular, calling close() on a readable InputStream could poison the connection pool. Work around this by disabling connection pooling: text/java 复制 {@code private void disableConnection...
接下来,我就以Java中用于操作Redis最常见的库Jedis为例,从源码角度分析下Jedis类到底属于哪种类型的API,直接在多线程环境下复用一个连接会产生什么问题,以及如何用最佳实践来修复这个问题。 首先,向Redis初始化2组数据,Key=a、Value=1,Key=b、Value=2: ...
