Thus, the read operations compete with log writing and the write operation for data pages from the buffer pool.
因而，读操作与日志写和缓冲池中的数据页的写操作之间存在竞争。
This operation is repeated until the replay log position reaches the current log position.
这个操作会一直重复，直到重放日志位置到达当前日志位置。
For instance, if log records are input to statistical analysis, a low number of failed log operation might be tolerable.
例如，如果日志记录只是用来进行统计分析，少数几次失败的日志操作将是可以接受的。
Reading from the audit log is a restricted operation that requires site administrator permissions.
需要注意，读取审计日志是一个受限制的操作，需要站点管理员权限。
But with a logging database, we are going to log every operation we perform.
但是，通过日志数据库，我们正在记录所执行的每个操作。
The log operation succeeds only on transaction commit, but a failure of the log operation doesn't cause the transaction to abort.
只有当事务提交的时候日志操作才会成功，但日志操作的失败并不会导致事务被中止。
The failure of a log operation does not cause the transaction to fail, and the log operation can succeed even if the transaction itself is aborted.
一个日志操作的失败不会导致整个事务的失败，并且即使在事务被中止的情况下日志操作仍旧可以成功。
For example, a service may require you to log on before calling another operation, which is termed a pseudo-conversational service.
例如，服务也许要求您在调用另一个操作之前先登录，这称为伪对话服务。
Be aware that no normal transaction operation is affected if such a log message should fail, but the log message itself is affected by the transaction's failure.
因为如果日志操作失败，并没有正常的事务操作受到影响，但如果事务失败，日志消息却会受到影响。
A log operation might not participate in atomicity at all.
不涉及事务原子性的日志操作。
The exception to this rule could be a log salvage operation where already saved logical logs are backed up again with the same object name, thereby inactivating the previous version.
不过这条规则也有一个惟一的例外，那就是日志抢救操作，这种操作再次用相同的对象名称来备份已经被保存的逻辑日志，从而使得前一个版本进入不活动状态。
Log error and continue (default) : If an error is encountered, the error is logged and the requested operation is performed.
Logerrorandcontinue(默认)：如果突然出现一个错误，记录错误并执行请求的操作。
I can wrap the object in a dynamic logging object that looks like the Customer object but sends notifications of a get or set operation to a log.
我可以把这个对象包装在一个动态日志对象内，这个对象看起来像Customer对象，但是会把get或set操作的通知发送给日志。
Process DML log records generated due to an alter operation while moving the rows from the old partition to the new table partition.
处理在将旧分区中的行转移到新表分区时因alter操作而生成的DML日志记录。
The other problem that we've had with Hadoop is the lack of support for a 'sync' operation in their distributed filesystem. This makes it unsuitable for storing a commit log.
Hadoop还有一个问题，在它的分布式文件系统中缺乏对“sync”操作的支持，因此不适合用来保存提交日志。
Once we know we are in the right context, we can prepare a log record based on the type of operation executed. The following code excerpt illustrates how it can be done.
一旦我们知道我们位于正确的上下文中，我们就可以准备一个基于被处理的操作类型的日志记录。
For the slow alter, alter fragment, or clustered index creation operations, the alter operation replay position is moved to the current log position before performing the operation.
对于slowalter、alter fragment或集群索引创建操作，在执行alter操作之前，alter操作的重放位置被移动到当前的日志位置。
Depending upon the distance between the replay position and the current log position and the size of the unspooled data in send queue, this operation might delay the alter operation.
取决于重放位置与当前日志位置之间的距离，以及发送队列中未假脱机的数据的大小，这个操作可能会延缓alter 操作。
The operation is sent to replicate using store-and-forward techniques triggered from a database log file or database triggers.
使用从数据库日志文件或数据库触发器触发的存储并发送 (store-and-forward)技术将操作发送给复制。
Finally, the read operation maps to SYSLOG_ACTION_READ to consume the available log messages.
最后，read操作会被映射到SYSLOG_ACTION _ read，以处理可用的日志消息。
Expect has a variety of "switches" to log or report aspects of its operation.
Expect有各种“开关”来记录或报告其操作的各个方面。
Successfully posting to the log is also considered a commit (the data is safely stored to persistent storage), allowing the database operation to complete and continue.
提交时也会查看是否成功发布到日志（数据是否安全地存储到持久性存储器），成功后才允许数据库完成操作或进行下一步操作。
Recall that returning a single character at an arbitrary position within a rope is an o (log n) operation.
返回rope内任意位置字符的操作是个o (logn)操作。
Used for internal data structure synchronization within a backup operation, such as database, log, or file backup.
用于备份操作(例如，数据库、日志或文件备份)中的内部数据结构同步。
Maintain a daily log of operation, maintenance and safety activities, and write reports on plant operation.
保持日常操作，维护和安全活动记录，并记录电厂运行报告。
To move a system database data or log file as part of a planned relocation or scheduled maintenance operation, follow these steps.
若要将移动系统数据库数据或日志文件的操作作为预先安排的重定位或预定的维护操作的一部分，请执行下列步骤。
If an error prevents a refactoring operation from completing, information about the error is written to the application event log, where any user who has "Normal user" permissions can view it.
如果因出错而无法完成重构操作，则有关该错误的信息将写入应用程序事件日志中，对此应用程序事件日志拥有“普通用户”权限的任何用户都可以查看该信息。
