如何解决java.lang.OutOfMemoryError:Weblogic中超出了GC开销限制？

我正在尝试删除大量数据，在本地系统上获取此数据，如何解决此问题。使用weblogic 12c，oracle atg。在dyn/admin上获取上述错误，并在线程“[STANDBY]ExecuteThread:'3'for queue:'weblogic.kernel.Default（自调优）”中的cmd prompt Exception上获取以下错误java.lang.OutOfMemoryError:超出了GC开销限制。

该异常+消息意味着您的JVM决定在垃圾收集上花费太多时间。。。相对于做有用的工作。这通常意味着堆几乎已满，GC正在以越来越高的频率运行（通常是徒劳的）继续运行

根据具体情况，可能的解决方案有：

获取更多的物理内存，以增加堆大小

查找并修复任何内存泄漏

使问题变得更小

在您的情况下，缩小问题可能涉及减少在每个事务中删除的对象的数量。

这是否回答了您的问题？我用过这款车，现在它可以正常工作了。但是性能太慢了，我删除了1000个订单，但仍然需要数小时的执行，仍然无法删除所有订单。我该怎么办？我正在从dcspp_订单表和所有有该订单条目的表中删除一个特定订单，就像其他11个表一样。我必须删除大约2050万个订单。您能建议一些有助于提高性能的方法吗。我还使用了JTA事务管理器。这是一个不同的问题。。。还有一个不同的问题。
