Weblogic 10上的EJB3 - 首次访问数据库时超时

时间:2012-01-27 09:20:11

标签: java timeout ejb-3.0 eclipselink weblogic-10.x

我有一个EJB3应用程序,我在各种环境中部署,即使用Apache webserver的Weblogic 10 for Windows和使用IIS webserver的Linux的Weblogic 10。我正在使用EclipseLink作为持久层。数据库在Windows机器上始终是Oracle 9.2。

我的persistence.xml将我(其中“我”是会话bean)连接到一个或多个Oracle数据源。有3个会话bean用于访问3个数据源,每个数据源一个。

在Windows!Weblogic上,这是开发环境,没有问题,但是当我在Linux机器上部署(测试和生产环境)时,所有会话bean在首次访问数据库时都会给出一次或两次超时异常,然后工作得很好。根据Weblogic控制台,任何配置都是相同的,而且我没有对生产环境中的设置的写访问权限,所以我还必须保持开发和安全性。测试一致。 因此,Weblogic控制台上的配置设置(例如增加事务超时)都不会。

我对这里遗失的内容有所了解吗?谢谢!

编辑:这是一个示例异常堆栈跟踪。每次都是一样的。

我想不出为什么两台机器会有所不同,但需要加以研究。解决方法可能是使用值为true的eclipselink.deploy-on-startup标志,这会导致某些EclipseLink初始化在前面而不是在第一次访问时完成。
