The effect on JVM heap sizes and performance (particularly when using persistent sessions) is dramatic.
这对JVM堆的大小和性能的影响（尤其在使用持久性会话时）相当大。
It should be noted that the JVM heap size is allocated from the DataFlowEngine (Execution Group) process.
应该注意的是，jvm堆大小是从DataFlowEngine(执行组)进程分配的。
A heap dump is typically a very large file that contains a list of all the objects currently on the JVM heap.
通常，堆转储通常是一个很大的文件，它包含当前jvm堆中所有对象的一个列表。
If a GC was triggered and there is still not enough room for the object then you have exhausted the JVM Heap.
如果GC被触发，但对象仍然没有足够空间，那么J VM heap耗尽。
The JVM heap size Settings are adjusted from a minimum to a maximum set of values until the optimal Settings are found.
您可以使用一组从最小到最大的值来调整J vm堆大小设置直到找到最佳设置。
This can help alleviate the issue of Heap exhaustion without the need to increase the JVM Heap to an excessive size.
这有助于缓解Heap耗尽问题，而无需将JVM Heap的大小增加得过大。
Processing a number of large messages, especially when running with concurrent threads, can lead to JVM Heap exhaustion.
处理一些大消息，特别是使用并发线程运行时，可能会导致JVM heap耗尽。
Your strategy, therefore, must rely on ensuring that each application is well behaved, with respect to its use of JVM heap resources.
因此，对于使用jvm堆资源而言，您的策略依据必须是确保每个应用程序行为良好。
Increasing the JVM heap size permits more objects to be created before an allocation failure occurs and triggers a garbage collection.
通过增加jvm堆大小，可以在出现分配故障并触发垃圾收集之前创建更多对象。
When the cache gets too large to fit into the JVM heap, dynacache disk offload writes the contents of the cache out to a file on disk.
当缓存大于jvm堆时，dynacache磁盘卸载会将缓存内容写到一个磁盘文件中。
JVM heap size Settings generally are adjusted upwards for larger thread pool sizes, but start the testing with minimal memory Settings.
一般来说，为了使线程池的大小更大，您可以上调J vm堆大小设置，但在开始测试时请使用最小内存设置。
Recommendation: Adjust the JVM heap size Settings in reasonable increments to determine the optimal memory Settings for the application.
推荐：通过合理地增加jvm堆大小设置来对它进行调整以确定应用程序的最佳内存设置。
In addition, WebSphere Application Server tuning of the JVM heap and threads pools is automated based on the size of the virtual machine.
此外，jvm堆和线程池的WebSphereApplicationserver调优会根据虚拟机的大小自动进行。
Recommendation: For each set of JVM heap size Settings, run one test with garbage collection turned on, and another with it turned off.
推荐：对于每一组jvm堆大小设置，请在一次测试的运行中启用垃圾收集，在另一次中禁用它。
If multiple large messages are being processed by a service at the same time, then available space within the JVM Heap can quickly disappear.
如果一个服务同时处理多个大消息，那么J VMHeap中的可用空间可能会迅速耗尽。
Make sure that the JVM heap size Settings are within the physical memory limits of the machine, along with any other applications on the same server.
请确保jvm堆大小设置与同一台服务器上的任何其他应用程序不超出机器的物理内存的限制。
Something to keep in mind when setting the maximum values for the servlet engine thread count is the amount of the maximum JVM Heap Size Settings.
在设置servlet引擎线程个数的最大值时请记住最大jvm堆大小设置的数量。
This way the JVM can maintain a single contiguous heap while growing it as needed (see Resources for an article on how to use the JVM heap parameters).
通过这种方式，JVM可以维护单一的、连续的堆空间，并根据需要增长(关于如何使用jvm堆参数请参阅参考资料)。
The trigger for a GC is usually an allocation failure - this occurs when the allocation of an object to the JVM heap fails due to insufficient available space.
GC的触发器通常是一个分配失败。分配失败是指，由于可用空间不足，无法将一个对象分配到jvm堆。
Increasing the size of your JVM Heap to compensate for JVM Heap exhaustion will result in more objects being able to be allocated before a GC is triggered.
增加JVM Heap的大小来补偿JVM Heap耗尽将导致GC触发前能够分配更多对象。
The aim of the GC is to clear up the JVM heap of any objects that are no longer required, thus providing enough space for the object that previously failed allocation.
GC的目标是清理不再需要的对象的JVM堆，从而向此前分配失败的对象提供足够的空间。
Set the contents of this file to the JVM maximum heap size required in bytes.
将此文件的内容设置为所需的最大 JVM堆大小（以字节为单位）。
The JVM allocates the heap during initialization.
JVM在初始化的过程中分配堆。
So never set the values of process heap size and JVM maximum heap size to be same.
因此，绝不要将进程堆大小值和JVM最大堆大小值设置为相同的数字。
The JVM does the core of its work in the heap.
JVM在堆中执行其工作的核心部分。
To understand what is going on, we need to familiarize ourselves with how the JVM USES system memory for its heap.
要理解其中的缘由，我们必须熟悉JVM如何将系统内存用作它的堆。
