在此种背景下(against this backdrop),rman的性能调整变得比以往都重要。 本文详细描述了在backup和restore操作期间,rman性能调整中,与buffer memory 相关的guidelines 这些guidelines 以如下系统为目标: the available I/O exceeds 100 MB/s, while memory, CPU, network consumption, and tape drive throughput do ...
direct buffer memory 如何查看 direct access memory DMA DMA(Direct memory access) 特性允许在CPU参与的情况下外设访问DDR。如常见的ARM SOC,CPU core通过AXI master,经常NOC(Network on a chipe)路由到DDR AXI SLAVE接口,实现DDR访问。在SOC没有DMA特性下,如果DDR需要和外设之间搬移数据,只能通过CPU 指令,这样...
生成ByteBuffer 的时候调用了 allication 方法,按下面一步接一步的调用,可以看到 System.gc() : 而上述参数:-XX:+DisableExplicitGC 会使 System.gc() 失效,因此当某些 nio 的引用到了 old 区又没发生 full gc 的时候,就会出现标题的 memory 异常了。
Buffer memory is a temporary storage area in the main memory (RAM) that stores data transferring between two or more devices or between an application and a device.Buffering compensates for the difference in transfer speeds between the sender and receiver of the data. ...
buffer memory: A memory system, usually of small capacity compared to a main-frame memory, that provides a buffer function between two digital activities. From: Reference Data for Engineers (Ninth Edition), 2002 About this pageSet alert

Memory use in an Immediate-Mode RendererA naïve implementation of an immediate-mode renderer might use a large amount of memory bandwidth. The next diagram shows that a large amount of memory is transferred during rasterization even with a simple cache for the framebuffer pixels and depth ...
java.lang.OutOfMemoryError: Directbuffer memory 错误后的总结。 发生原因: 用来nio,但是 direct buffer 不够 解决办法 1)检查是否直接或间接使用了 nio ,例如手动调用生成buffer的方法或者使用了 nio 容器如 netty, jetty, tomcat 等等; 2)-XX:MaxDirectMemorySize 加大,该参数默认是 64M ,可以根据需求调大试...
