tmpfs文件系统是一个虚拟内存文件系统。
内存文件报告可以向您展示许多内存外泄。
该值还包括往返于非缓存、映射后的内存文件的页面。
This value also includes the pages to or from non-cached mapped memory files.
内存文件存储是 /dev/shm/dumpmem
现在,要从全部共享内存文件读取和打印所有记录,创建一个循环。
Now, to read and print all the records from the entire Shared memory file, create a loop.
使用tmpfs虚拟内存文件系统和绑定挂装(第 3部分)
Using the tmpfs virtual memory filesystem and bind mounts (Part 3)
易语言自定义数据类型读写源码例程程序结合易语言内存文件的操作,实现自定义数据类型数据的读写。
Easy language custom data types to read and write source routine procedures combined with easy language to operate the memory file to achieve custom data type data read and write.
在Linux系统中,您不能通过使用通常用于文件显示的cat实用工具来查看共享内存文件(常指的是shm文件),因为这些shm文件是以二进制的格式存储的。
You cannot view the Shared memory files (commonly referred as SHM files) by using the cat utility generally used for file display in Linux since these SHM files are in a binary format.
如果我们想要探究内存映射文件结构的话,不需要构造一个流,只要找到该资源的名字即可。
If we explore the construction of the memory mapped file we can see that there is no stream, we just name the resource.
应用程序状态可以存储在内存、文件或者数据库中。
Application state may be stored in memory, in files, or in a database.
清单27中的代码片段展示了如何从外部内存删除文件。
The Listing 27 snippet shows how to delete a file from external memory.
证书可以从现有的内存结构或文件中导入。
The certificate can be imported from an existing memory structure or a file.
由于消息在传输到队列管理器之前得到加密,因此数据在内存、队列文件、日志和跟踪记录中受到保护。
Because the messages are encrypted before they are passed to the queue manager, the data is protected in memory, in the queue files, in logs, and in traces.
通过使用内存操作代替文件操作,循环缓冲区使得日志记录的效率更高。
A ring buffer makes logging efficient by using memory operations in place of file operations.
将XML文件加载到内存。
进程的虚拟地址空间中的区域可被映射到物理内存、文件或任何其他可寻址存储。
Regions in a process's virtual address space can be mapped to physical memory, to a file, or to any other addressable storage.
同样,您希望将文件内存分页到磁盘中,而不是计算性内存中。
Again, you want the file memory paged to disk and not the computational memory.
最后,安装更多内存让文件系统可以把文件和元数据缓存在内存中。
Finally, having extra memory on hand allows the file systems to cache files and metadata in memory.
在将文件从磁盘读取到内存时对文件解密,因此文件数据能够以明文格式保存在内存中。
The files are decrypted when they are read from the disk into memory so that the file data kept in memory is in clear format.
在创建或更新共享内存分区概要文件时,可以在内存配置部分中找到选择分页VIOS分区的选项。
When creating or updating Shared memory partitions profiles you can find the option to select the paging VIOS partitions in the memory configuration section.
我们使用这些参数来确定我们的系统是倾向于使用计算性内存、还是文件内存。
We use these parameters to determine whether our system favors computational memory or file memory.
将这些参数设置为适合您的系统的值,以确保对计算内存或者文件内存进行优化。
Setting these parameters determine the appropriate value for your system to ensure that it is tuned to either favor computational memory or file memory.
包括读写文本文件的便捷方法,快速地列举目录,对内存映射文件的支持。
These include convenience methods for reading and writing text-based files, significantly faster directory enumeration, and support for memory mapped files.
首先,在输入方面,它将完整的XML文件读入内存,所以如果文件非常大或者需要处理XML数据流,就不能使用这个模块。
First, on input it reads the entire XML file into memory, so if the file is too big, or if you're dealing with a stream of XML data, you can't use the module.
这样,我们就创建了一个内存映射文件。
This will create the memory mapped file but to start using it we will need a map view.
这意味着消息在内存、日志文件、跟踪记录和返回队列结构的文件中是可读的。
This means that the text of the messages is readable in memory, in log files, in traces, and in the files that back the queue structures.
这意味着不必将整个文件读取到内存中才能着手处理文件。
This means that the whole of the file does not have to be read into memory before processing of the file can commence.
如何访问文件就跟前述的示例一样了。千万记住,如果你关闭了内存映射文件,那么它就不能访问了。
The access to the file USES the same syntax as the previous example, remember that if you close the memory mapped file this will be non accessible, this issue catches many developer.
创建合适的流之后,现在就可以创建内存映射文件了。
With the stream in place, we can now create the memory mapped file. Let's see an example.
在本文后面,我将讨论第8种类型MappedByteBuffer,它用于内存映射文件。
I'll discuss an eighth type, MappedByteBuffer, available for memory-mapped files, later in this article.
