不可行的方法最初我直接修改catalina.sh, 将JAVA_OPTS变量加上了 -server -Xms1G -Xmx1G -XX:+UserG1GC最初看起来没啥问题,但是当服务器运行几天后,发现执行shutdown.sh无法关闭tomcat, 错误信息如下: # root@iZ94hjppdqzZ:~/projects/taolijie# cat hs_err_pid5519.log # There is insufficient memory for the Java Runtime

遇到问题 在服务器上运行 nexus 出现Native memory allocation (mmap) failed to map 838860800 bytes for committing reserved memory问题. 原因:查资料后是因为运行 nexus 需要 800m 的内存,而机器配置是1G,剩余可用的只有几十兆,所以导致无法启动 解决办法 方法一: 扩大机器配置: 方法二: 设置交换内存swap(一般设置为内存的两倍大小): dd if=/dev/zero of=/tmp/

一.缓存机制介绍 在Linux系统中,为了提高文件系统性能,内核利用一部分物理内存分配出缓冲区,用于缓存系统操作和数据文件,当内核收到读写的请求时,内核先去缓存区找是否有请求的数据,有就直接返回,如果没有则通过驱动程序直接操作磁盘.缓存机制优点:减少系统调用次数,降低CPU上下文切换和磁盘访问频率.CPU上下文切换:CPU给每个进程一定的服务时间,当时间片用完后,内核从正在运行的进程中收回处理器,同时把进程当前运行状态保存下来,然后加载下一个任务,这个过程叫做上下文切换.实质上就是被终止运行进程
