BIRT运行时错误- java.lang.OutOfMemoryError:超出GC开销限制

Question

我正在使用BIRT在一台已知能够处理相对较大的数据集的服务器上运行报告。但是，此报告将无法正确运行，并抛出以下错误：

Caused by: java.lang.OutOfMemoryError: GC overhead limit exceeded

考虑到这份报告的性质，我不确定为什么会达到内存限制。它返回大约20行，并对数据进行有限的预处理。

完整错误如下：

我终于解决了这个问题，只有在使用启动脚本启动tomcat时，setenv.bat或setenv.sh才会运行。如果您已将tomcat设置为服务，则不会调用setenv。

设置tomcat服务后，执行tomcat8w.exe (我使用的是tomcat版本8，请使用与您的版本对应的可执行文件)

您将看到一个窗口，单击java选项卡设置初始内存池和最大内存池。您的birt报告开始正常工作

我们的理解是，在将tomcat安装为服务时，您必须使用默认服务名称。如果您提供了不同的名称，则使用

tomcat8w //MS//

这将允许您为tomcat配置JVM。
