在我的项目中,我有一个数据库,许多客户与数据库连接。 并行进出和写作工作良好。 现在的问题不是从数据库中每秒重载数据,以便始终保持数据现状。
Does Eclipselink provide a trigger mechanism on (automatically?) reload the data if the database is changed? How would one use this trigger?
感谢!

我所看到的一种解决办法是利用数据库中的触发器向您发送联合监测系统的信息。 之后,该信息在一家多边开发银行收到,EclipseLink切身可被废止或复读。 这种办法在Oracle数据库中运行良好,在该数据库中,触发器将信息输入AQ表。
这些都是我熟悉的房舍管理处的具体解决办法,但挑战始终是要收到更改通知,以列入表格和PK的数值,而不是记录,并确保你不被告知自己作出的改动,或在一定程度上容易从你自己的变化中抽出通知。
我认为,GoldenGate有助于解决这一问题,但尚未尝试。
