The first section provides information about the date and time of the lock timeout occurrence and about the corresponding instance and database.
第一部分提供与锁定超时发生的日期和时间，以及相应的实例和数据库相关的信息。
These systems lock files so that only one developer has write access to the central repository at a time.
这些系统对文件进行加锁，这样在某个时间只有一个开发人员对中心仓库具有写入权限。
On the other hand, if the lock is held for a longer time, spinning is wasteful as the spinning thread consumes CPU without doing anything useful.
另一方面，如果锁被占有很长时间，那么自旋的线程只会消耗CPU而不做任何有用的工作，因此带来浪费。
Pattern authors can exercise varying degrees of control over deployment by choosing to lock deployment time parameters, ensuring fixed values for every deployment.
模式作者可以尝试对部署进行不同程度的控制，选择锁定部署时间参数，确保为每种部署使用固定的值。
If you are going to hold the lock on the collection during an entire iteration, then other threads may be stalled waiting for the collection lock for a long time.
如果您要在整个迭代期间都保持对集合的锁，那么其他的线程就会在锁外停留很长的一段时间，等待解锁。
For example, if the database parameter LOCKWAIT is set to 20 seconds, a transaction waiting for a lock is rolled back after 20 seconds of wait time.
例如，如果数据库参数LOCKWAIT 被设置为20秒，一个等待锁的事务在过了 20 秒的等待时间后被回滚。
In this situation, if no lock is available at the time of the request, the application immediately receives a -911.
在这种情形中，如果请求时没有可用的锁，那么应用程序立刻会接收到- 911。
In this situation, the application will wait for a lock (if one is not available at the time of the request) until either the lock is granted or until a deadlock occurs.
在这种情形中，应用程序将等待获取锁(如果请求时没有可用的锁)，一直到被授予了锁或出现死锁为止。
The shorter the time a thread holds a given lock, the lower the probability that another thread will request it while the first thread is holding it.
一个线程占用一个给定锁的时间越短，另一个线程在该线程仍占用锁时请求该锁的可能性就越小。
In addition, we lock the value to ensure a user does not accidentally change this value at deploy time (Figure 13).
另外，我们锁定这个值，以确保在部署时用户不会意外地更改它(图13)。
When multiple threads ask for the same lock at the same time, one wins and acquires the lock, and the others block.
在多个线程同时请求同一个锁时，会有一个线程获胜并得到锁，而其他线程被阻塞。
Before the "LEGEND" section, the profiling result report first summarizes all JUC lock contentions in the program, in descending order by lock contention count, then contention time.
在“LEGEND”段之前，结果报告首先，按照锁竞争次数和时间的降序，总结了程序中全部的JUC锁竞争。
The cost is that the duration for which the lock is held may be lengthened, increasing the amount of time other threads might be locked out and also increasing the probability of lock contention.
代价则是持有锁的时间可能会变长，从而延长了其他线程被锁在外面的时间，也会增大锁争用的可能性。
In this example, DB2 performed 1150 lock escalations within an hour time period.
在这个示例中，DB 2在一小时中增加了1150个锁。
The only reason for the delay could be that there are too many writer threads, and sufficient time has elapsed before a lock could be acquired.
造成延迟的惟一原因是写线程太多，要等待很长时间才能获得锁。
These statistics include how the lock was acquired, the total amount of time the lock was held, and the average amount of time that the lock was held.
这些统计数据包括锁被请求的方式、锁被持有的总时间以及锁被持有的平均时间。
When we were in grad school, a hacker friend of mine who spent too much time around MIT had his own lock picking kit.
我读研究生时，一个成天出入麻省理工学院的黑客朋友自己拥有一套撬锁装备。
Futexes optimize the time to obtain an uncontested lock without relying on the kernel; kernel intervention is required only for contested locks.
Futexes对获得非竞争锁的时间进行了优化，而不用依赖内核；只有对竞争的锁才需要内核干涉。
So now that you've got WidgetLocker set up as your lock screen, it's time to start customizing it.
好了，既然你现在已经将WidgetLocker设为你的锁定屏幕，那么是时候开始自定义它了。
The VM sometimes calls the Core (when defining a method for example) which acquires the Core lock, but most of the time it just runs concurrently.
VM有时候也会调用Core（例如定义一个方法）请求Core锁，但是大多数时候它都是并行执行的。
You can see from this screenshot that the JLAsink monitor has had 9,161 gets made on it and that the requesting thread was blocked trying to obtain the lock 25 percent of the time.
可以从此屏幕截图中看到，JLAsink 监视程序进行了 9,161 次 get，并且请求线程被阻塞，阻止它获得 25%的锁时间。
The frequency TAB shows the list of SQL statements with their frequency of execution along with the average response time, lock wait, and wait IO time.
Frequency选项卡按执行频率列出sql语句并显示平均响应时间、锁等待时间和IO等待时间。
"The sea level rise is a much slower thing, so it will take a long time to happen, but we will lock into it, based on the peak level of [carbon dioxide] we reach in this century," Solomon says.
“海平面上升是一个缓慢得多的事情，因此将需要很长时间才能发生，但我们将基于本世纪达到的二氧化碳峰值锁定它的水平。”所罗门说。
This routine takes in two arguments, the second being the absolute value of time by which, if the lock could not be acquired, the routine returns with a non-zero status.
这个例程有两个参数，第二个参数是绝对时间值。如果在到达这个时间时还无法获得锁，例程会返回且状态码非零。
In a hard lock-up, investors have no right to redeem before their time is up; in a soft lock-up, they can get out early but have to pay a redemption fee of, say, 3-5%.
在硬性期权锁定中，投资者在到期之前无权赎回其投入的资金；在软性期权锁定中，他们能够早早的退出但不得不支付据说有3 - 5%的赔偿金。
You can use one of these custom event handlers to further lock down which tabs are enabled or disabled at any given time.
可以使用这些定制事件处理程序中的一个来进一步控制在给定的时间哪个选项卡被启用或禁用。
An optimization like this would not be possible in a statically compiled environment because the information about lock usage patterns is not available at static compilation time.
像这样的优化在静态编译环境中是不可能的，因为关于锁使用模式的信息在静态编译时得不到。
The next time you see a woman you want to meet, LOCK your eyes on her!
下次看见一个你想见的女人时，用你的目光把她锁定。
While spin locks are CPU-intensive and appear inefficient, they can be more efficient than suspending the thread and subsequently waking it up if the lock in question is held for a very short time.
虽然旋转锁是cpu密集型的，显得效率低下，但是如果争夺的锁被持有的时间非常短，那么旋转锁要比暂挂线程然后再唤醒它更有效率。
