The core of this model is to make the queue length of node proportional to ( is the degree of node and is an allocation parameter).
模型的核心是使节点的队列长度与成正比（为节点的度，为分配参数）。
This parameter only causes an allocation of log files when the logprimary value is exceeded, which most likely can happen during a series of long uncommitted transactions.
该参数只会当超过logprimary值时才会分配日志文件，这种情况最有可能在一系列长时间未提交的事务期间发生。
As we discussed in the previous section, each log file created will have the same allocation of space based upon the logfilsiz parameter.
正如我们在前一节中讨论的，根据logfilsiz参数为所创建的每个日志文件分配相同的空间。
