使用共享内存对象写数据。
确保Web服务器用户能够向该目录写数据。
Ensure that this directory is writable by the Web server user.
写数据则需要打开一个输出数据源并在其内创建一个数据层。
Writing data requires opening an output data source and creating a data layer within it.
存放数据的时候，他先要获得互斥锁，再往总线上写数据，最后再释放互斥锁。
When publishing its data, it would acquire a mutex, do writes to the bus, and release the mutex.
在写数据时，主机总线适配器(HBA)根据块数据和逻辑块地址生成dif。
On a write, the DIF is generated by the host bus adapter (HBA), based on the block data and logical block address.
s锁允许使用只读查询的并发应用程序访问目标表，但是防止应用程序写数据到表中。
The s lock allows concurrent applications that use read-only queries to access the target table, but applications attempting to write data to the table are prevented from doing so.
当然，这不能彻底解决不及时写数据块的问题，但是，更频繁地写元数据也确实促进了更频繁地写数据。
Of course, this does not directly address the problem of not writing data blocks in time, but writing metadata more frequently does encourage data to be written more frequently as well.
当用户写数据时(INSERTUPDATE和DELETE操作)，则应用写访问规则，写访问规则可总结如下。
Write access rules are applied when data is written (INSERT, UPDATE, and DELETE operations) and can be summarized as follows.
将其标记为 @Transactional(readOnly=false)，这样可以在读/写数据库事务下执行SQL查询。
Mark them @Transactional(readOnly=false) such that the SQL queries are executed under read/write database transactions.
如果将来自unicode数据库的数据导出到一个客户机，但是这个客户机并不使用Unicode作为它的标准编码页，那么在写数据文件时可能会丢失数据。
If you export data from a Unicode database to a client that does not use Unicode as its standard code page, you may lose data when the data file is written.
注意，可以使用sync命令将缓冲区缓存中的请求发送到存储媒体(迫使所有未写的数据发送到设备驱动程序，进而发送到存储设备)。
Note that you can use the sync command to flush the buffer cache out to the storage media (force all unwritten data out to the device drivers and, subsequently, to the storage device).
但如果把投入写操作系统的精力用来推行数据标准，那些理想主义者应该会离他们的理想更接近。
But if the same effort in writing operating systems were put into marketing data standards, the idealists would be a step closer to their better world.
DB 2直接从磁盘读(写)lob数据。
在调用跟踪节点时，即使它不写跟踪数据，它也会产生处理开销。
When a trace node is invoked, it results in a processing overhead even if it does not write trace data.
在这种模式下，写操作是在数据存储到本地磁盘并镜像到对等节点内存后被确认的。
In this mode, the Write operation is acknowledged after the data is stored on the local disk and mirrored to the peer node's memory.
另一个防止数据丢失的技术是写屏障。
Another technique that helps with data corruption is write barriers.
由于所有数据存储写必须在两个位置上同步地执行，这种解决方案的设计必须考虑主站点与辅助站点之间所需的IO带宽。
Since all data storage writes must be performed synchronously at both locations the solution design must account for IO bandwidth needed between the primary and secondary sites.
ZFS使用即写即拷模型来管理存储中的数据。
ZFS USES a copy-on-write model for managing data on the storage.
执行操作通常会导致读、写或修改一个或多个持久性数据。
Execution of an operation will typically cause one or more persistent data records to be read, written, or modified.
第三种降低数据丢失风险的选择是关闭磁盘的写缓存功能。
A third alternative to help reduce the risk of data corruption is to turn off the write cache on your drives.
另一半是称作预写式日志记录(write - ahead logging)的数据库管理器实现。
The other half is a database manager implementation called write-ahead logging.
HADR复制数据的基本方法是将DB 2日志写同时发送到本地磁盘和备用系统。
The basic method by which HADR replicates data is to send DB2 log writes simultaneously to the local disk and to the standby system.
在一个信号量保护大量数据时，如果一个或多个任务使用它进行写操作，这个信号量就会成为系统瓶颈。
When a semaphore protects a large amount of data, assuming one or more tasks USES it on a write basis, the semaphore becomes a bottleneck within the system.
某一天，在网页界面制作和分享一份数据分析将如同写一篇博文般简单。
Someday, creating and sharing a data analysis through a web dashboard should be as easy as writing a blog post.
图6显示了文件访问的写模式时间队列如何改善数据一致性
Figure 6 demonstrates how a write mode time queue for file access can improve data consistency
相反，应该考虑创建少数几个调度优先级高的写线程，把应该确保添加到队列中的数据交给这些线程。
Instead, consider creating a few writer threads with higher scheduling priorities, and hand over data to those threads that should always be pushed into the queue.
当创作数据绑定时，会将消息标头传入读或写方法，并允许协议标头中的字段确定转换逻辑。
When authoring a Data Binding the message headers were passed into the read or write method, allowing transformation logic to be determined by a field in the protocol header.
当一端对一个套接字执行写操作时，可确保对等端读出的数据大小与此相同(请参见图5)。
When a peer performs a write on a socket, it is guaranteed that this same-sized chunk of data will be read at the peer endpoint (see Figure 5).
如果有很多数据修改操作，而查询较少，那么应该将注意力放在好的写性能上。
If you have very frequent data modification operations and less queries, you should focus on good write performance.
这两个写通道中有一个定义用来在数据可用时对CPU产生外部中断，另外一个则不具有通知机制。
One of those write channels is defined to generate external interrupts on the CPU when data is available, and the other does not have a notification mechanism.
