Oracle JDBC 自带连接池

 http://www.diybl.com/course/3_program/java/javajs/2008429/111906.html

 

如果要使用池的话,就必须使用OracleConnectionCacheImpl,共有三种池的策略:

DYNAMIC_SCHEME(是动态增加.用完如果超过上限则关掉)

The cache will create connections above the specified maximum limitwhen necessary   but will in turn close connections as they arereturned to the cache until the number of  connections is within themaximum limit. Connections will never be cached above the  maximumlimit. This is the default setting.

FIXED_RETURN_NULL_SCHEME  (直接返回Null)

The cache will return a null connection once the maximum connection limit has been  exceeded.

FIXED_WAIT_SCHEME  (始终等待)

The cache will wait until there is a connection available and will then return it to the  calling application.
