直接内存:并不是JVM运行时数据区的一部分, 可直接访问的内存, 比如NIO会用到这部分。 按照JVM规范,除了程序计数器不会抛出OOM外,其他各个内存区域都可能会抛出OOM。 最常见的OOM情况有以下三种: java.lang.OutOfMemoryError: Java heap space --->java堆内存溢出,此种情况最常见,一般由于内存泄露或者堆的大小设...

the compute function is disabled. In this case, you can start the compute instance only if the value of -Xmx in the JVM configuration is no less than the sum of memory.heap-headroom-per-node and query.max-memory-per-node configured for ...
when I say instance , I mean the domain or cluster 's member , if I just can set a jvm parameter for a domain , dose that mean all the member in the cluster must use the same jvm's setting ? > Hmm, may be by "instance" we mean different things? > :) > For me one GF dom...

Our default is to use 1/4 of the JVM heap formemtable_heap_spacein the cassandra.yaml. For write oriented application and/or on SKUs with small memory this can lead to frequent flushing and fragmented sstables thus requiring more compaction. In such cases increasing, it to at least 4048 ...
Max memory = [-Xmx] + [-XX:MaxPermSize] + number_of_threads * [-Xss]MaxPerm/MetaSize + MaxDirectMemorySize + Xmx(线程栈一般只有几十M,可以忽略)这差不多就是JVM可以占用的最大内存了整个Java进程分为heap和non-heap两部分,每部分有以下几个概念: initrepresen reserved_mem jvm java sed JVM...
