1.-Xms与-Xmx分别是设置jvm的堆内存的初始大小和最大大小。 2.-Xmx2048m:等价于-XX:MaxHeapSize,设置JVM最大堆内存为2048M。 3.-Xms512m:等价于-XX:InitialHeapSize,设置JVM初始堆内存为512M。 4.适当的调整jvm的内存大小,可以充分利用服务器资源,让程序跑的更快。 测试: 1== 可以很明显的感觉到输出速...
If the parameter settings are not appropriate, the container may be forcibly shut down due to OOM errors even though the application memory does not reach the upper limit of the JVM heap size. For more information, see What do I do if the 137 exit code appears in my container? We recomm...

Two JVM options are often used to tune JVM heap size: -Xmx for maximum heap size, and -Xms for initial heap size. Here are some common mistakes I have seen when using them: * Missing m, M, g o ...
