You might instinctively conclude that setting a more detailed trace level will generate more records and cause the buffer to wrap more quickly. 您可能会本能地断定设置更详细的跟踪等级将生成更多的记录并导致缓冲区得到更快的包装。
First, we will turn the trace facility on, specifying an8-MB trace buffer. 首先,我们将打开跟踪功能,同时指定一个8-MB的跟踪缓冲区。
There are some important things that you should note about the trace buffer 关于跟踪缓冲区,以下有些重要的事情需要注意
As long as there is a single process attached to the shared trace buffer, you will not be able to change the buffer size. 只要共享跟踪缓冲区上附加了一个进程,就不能更改缓冲区的大小。
For performance reasons, the trace facility does not allow you to change the trace buffer size dynamically. 由于性能的原因,跟踪功能不允许动态更改跟踪缓冲区的大小。
The default and minimum trace buffer sizes depend on the version of DB2, and the maximum trace buffer size depends on the platform. 缓冲区的默认大小和最小值取决于DB2的版本,跟踪缓冲区的最大值取决于平台。
The verbose trace will display data from the parameters of system calls (-x all) and the contents of the buffer for both Read (-r all) and Write (-w all) calls. 详细的跟踪会显示来自系统调用参数的数据(-xall)以及Read(-rall)和Write(-wall)调用的缓冲区的内容。
Collection options include turning a trace on or off; specifying the trace buffer size; specifying or changing trace options; dumping a trace; and clearing the trace buffer. 收集选项包括打开或关闭跟踪;指定跟踪缓冲区大小;指定或更改跟踪选项;转储跟踪信息;以及清除跟踪缓冲区。
Depending on trace volume, buffer size, and the bandwidth of the output device, multiple buffers might be allocated to a given thread to keep pace with trace data that is being generated. 根据跟踪量、缓冲区大小和输出设备的带宽,可以将多个缓冲区分配给给定的线程,从而与生成跟踪数据的速度相匹配。
If you are tracing to shared memory, the size of the trace buffer controls the size of the dump file. 如果是在跟踪共享内存,跟踪缓冲区的大小将控制转储文件的大小。
In this case, we will trace only the buffer pool services component. 在本例中,我们将只跟踪缓冲池服务组件。
This allocation allows the thread to continue to run while a full trace buffer is written to the filesystem. 当一个跟踪缓冲区满了时,将它写到文件系统中,这使线程能够连续运行。
We will be tracing into shared memory ( rather than to a file), using the-i option, which stops the trace as soon as the buffer is full. 我们将使用-i选项将跟踪信息存放到共享内存(而不是一个文件),在这种情况下,当缓冲区被充满时,就立即停止跟踪。
You can write trace data to a file continuously as an extension to the in-storage trace, but instead of one buffer per thread, at least two buffers per thread are allocated. 可以连续地将跟踪数据写到文件中,作为存储内跟踪的扩展;但是在这种情况下不是为每个线程分配一个缓冲区,而是至少分配两个。
This collection option stops tracing on demand; all processes suspend tracing, but the contents of the trace buffer are preserved so that they can be dumped later. 这是一个收集选项,它根据需要停止跟踪。这时,所有进程都挂起跟踪,但跟踪缓冲区的内容被保存起来,以便以后转储到文件中。
With different trace levels set for various registrations, the influx of data into the buffer also depends on the amount of activity in each connection being traced. 通过为各种不同注册设置不同跟踪等级,数据进入缓冲区还依赖于在每个被跟踪的连接中的活动数量。
Trace buffer doesn't save top of stack or contents of memory referenced by registers. 跟踪缓冲区并不保存栈顶或由寄存器所指向的内存的内容。
Trace commands mentioned at the beginning of this topic automatically open trace buffer. 在这个话题的开始提到的跟踪命令自动打开跟踪缓冲区。
Notice that displayed count is dynamical and doesn't account for the old commands discarded from the trace buffer. 注意显示出来的数字是动态的,而且不对已经从跟踪缓冲区中丢弃的指令镜像。
In this work, an on-line sweeping technique for the determination of trace impurity in nateglinide by using SDS buffer solution was developed. 利用在线推扫富集技术建立了毛细管电色谱测定新药那格列奈中痕量杂质的方法。
According to the analysis on the uncertainty of urban rail trains in operation, the article proposes that the trace train interval time consists of the minimum interval time and average necessary buffer time. 通过对城市轨道交通列车实际运行不确定性的分析,提出城市轨道交通追踪列车间隔时间是由最小列车间隔时间和平均必要缓冲时间两部分组成。
A new catalytic spectrophotometric method for determination of trace Mn(ⅱ) was developed based on the catalytic effect of Mn(ⅱ) on the determination reaction of acid chrome blue K with KIO_4 in buffer solution ( pH 11.90). 研究了测定痕量锰的新催化光度法,在pH11.90的条件下,锰(Ⅱ)催化高碘酸钾氧化酸性铬蓝K的反应。
Trace Buffer was widely applied in recording the historical track in the period of the programs 'execution. And this convenience is used in many kinds of In-circuit Emulators and Oscilloscopes. 跟踪缓冲可以记录程序执行的历史轨迹,这在各种在线仿真器(ICE)和逻辑分析仪中得到了广泛的应用。
