Using a single file is problematic, especially in a multi-user system because of issues of file locking and the performance problems associated with working with a single, large file. 使用单个文件可能会存在一些问题,特别是在多用户的系统中,因为在使用单个、较大的文件时,可能会出现与其相关联的文件锁定和性能问题。
You might have some ideas about using file locking or other operating system-specific tricks to synchronize access to a file in a distributed environment. 您此时可能想到使用文件锁或其他特定于操作系统的技巧,以在分布式环境中同步对文件的访问。
File object locking is not available, but the modified block storage technique can be introduced here the way we did in this article to maintain data consistency. 文件对象锁定不可用,但已修改的块存储技术可在此引入,按照本文介绍的方式保持数据一致性。
File locking is a very tricky issue and race conditions abound. 文件加锁是一个非常棘手的问题,很多时候都存在竞争条件。
Some provide file locking to prevent concurrent access. 有些提供了文件锁来防止多个用户的并行访问。
The code implements the file locking mechanism in Eucalyptus. 代码实现了Eucalyptus中的文件锁定机制。
Using scoped_lock, you don't need to explicitly lock or unlock the file; the locking occurs inside the constructor, and the unlocking happens automatically whenever you exit the scope. 如果使用scopedlock,就不需要显式地锁定或解锁文件;锁定发生在构造器内,每当您退出该范围,就会自动发生解锁。
In this article, you learn how to use the Boost IPC library to implement shared memory objects, message queues, and synchronized file locking. 本文中将学习如何使用BoostIPC库实现共享内存对象、消息队列和同步文件锁。
In addition, this new version of the NFS protocol supports byte range file locking, whereas previous versions used the lockd protocol provided by the Network Lock Manager. 此外,这个新版本的NFS协议支持字节范围的文件锁定,而先前版本使用的是网络锁管理器(NetworkLockManager)提供的lockd协议。
As I noted previously, the necessary hash data structures were retrieved and updated using tie'd variables and MLDBM file locking. 正如我在前面介绍的那样,可以使用tie'd变量和MLDBM文家锁定来检索和更新所需的哈希数据结构。
CIFS allows multiple clients to access and update the same file, while preventing conflicts with sophisticated file sharing and locking semantics. 在使用完善的文件共享和锁定语义来防止冲突的同时,CIFS允许多个客户端对同一个文件进行访问和更新。
To implement file sharing and locking mechanism we have created a class called WalrusVirtualBlockManager. 为了实现文件共享和锁定机制,我们创建了一个名为WalrusVirtualBlockManager的类。
File safety specifications ( so that multiple machines can access the same file without locking problems and opportunistic locking) 文件安全规范(这样,多台计算机就可以访问同一个文件,而不会出现锁定问题和伺机锁定)
Introducing file locking to Walrus 引入对Walrus的文件锁定
File locking status and errors. 文件锁定状态和错误。
Methods of file locking and record locking or file unlocking and record locking or file unlocking and record unlocking were given. 给出,文件、记录加锁解锁的方法及解决死锁问题的途径。
Disable the use of exclusive file locking and put in place measures to prevent overloads or network partitions. 解除文件排他锁定功能,并采取措施来防止过载或网络划分。
If you scan these files, serious performance problems may occur because of file locking. 如果扫描这些文件,则可能会由于文件锁定而出现严重的性能问题。
Could not open file for reading. Close any other application that may be locking the file. 无法打开文件进行读取。关闭其它可能锁定该文件的应用程序。
Installs support for file sharing and file locking. 安装文件共享和文件锁定的支持。
I talls su ort for file sharing and file locking. 安装文件共享和梦幻西游最低配置文件锁定的支持。
Disable new file sharing and locking semantics. 禁用新文件共享及锁定语义。
Having analysed the method of file-locking in WPS, this paper gives the means for locking for the password of a locked file. 通过分析WPS系统对文件加密的方法,给出了查找加密文件口令的方法。
This paper introduces XENDC/ SE from five aspects: discretionary access control, audit, file encryption, trusted path, terminal locking. 文章从存取控制、审计、文件加密、可信路径、终端锁定等方面,介绍了XENIX/SE的研究与实现。
