如果该比率很高，则它可能表明您所定义的页清除程序太少了。
If this ratio is high, it may indicate that you have too few page cleaners defined.
增加页清除程序的数量还会减少“软”故障(比如断电)的恢复时间，因为磁盘上数据库的内容在任何给定时候都是比较新的。
Increasing the page cleaners will also reduce recovery time from soft failures, such as power outages, because the contents of the database on disk will be more up-to-date at any given time.
如果没有配置页清除程序，则应用程序可能会遇到不时发生的“日志已满”情况。
If no page cleaners are configured, your applications may encounter periodic "log full" conditions.
通过将这个变量设置成on，可以为页清除提供一种比缺省方法(基于CHNGPGS_THRESH和LSN间隙触发器)更积极的方法。
Setting this variable to on provides a more proactive approach to page cleaning than the default approach (based on CHNGPGS_THRESH and LSN gap triggers).
为了尽可能好地进行页清除。
实际上，test6和7已表明，如果没有积极地进行页清除，那么在使用NLI的情况下，Insert加上提交所耗费的总时间要更长一些。
In fact, as shown by tests 6 and 7, if page cleaning is not done aggressively, the total elapsed time for Iisert plus commit can be longer with NLI.
不过，test8表明，将NLI与积极的页清除一起使用的时候，可以大大减少耗时。
However, as test 8 showed, utilizing NLI with aggressive page cleaning can shorten the elapsed time substantially.
页清除程序太少会使故障恢复时间变长。
Too few page cleaners increases recovery time after failures.
NUM_IOCLEANERS是一个数据库配置参数，它可以让您指定数据库的异步页清除程序的数目。
NUM_IOCLEANERS is a database configuration parameter that lets you specify the number of asynchronous page cleaners for a database.
这个参数决定缓冲池中脏页的阈值百分比，当脏页达到这个百分比时，就会启动页清除。
This parameter determines the threshold percentage of dirty pages in the buffer pool at which page cleaning will be initiated.
在具有大缓冲池的环境下，也可能需要配置较多的页清除程序。
Environments with large buffer pools may also require more page cleaners to be configured.
在具有高更新事务率的环境下，可能需要配置较多的页清除程序。
Environments with high update transaction rates may require more page cleaners to be configured.
在数据库代理程序需要缓冲池中的空间之前，这些页清除程序将缓冲池中已更改的页写到磁盘。
These page cleaners write changed pages from the buffer pool to disk before the space in the buffer pool is required by a database agent.
页清除率，或者说总缺页率，可能导致计时上的很大不同，使得性能比较容易产生误解。
The rate of page cleaning, or the total absence of it, can cause large differences in timings which can make performance comparisons misleading.
然而，当test8中采用了更积极的页清除时，性能就大大提高了，这主要是因为Commit的时间缩短了超过5秒钟。
However, with the more aggressive page cleaning in test 8, performance was improved substantially, mostly through the Commit time being reduced by over five seconds.
页清除器(cleaner)可用，并且被数据库管理器激活。
A page cleaner is available and is activated by the database manager.
在这个新的startup_ 32函数(也称为清除程序或进程0)中，会对页表进行初始化，并启用内存分页功能。
