内核键集是内核键集合，以及对它们进行读写所需的权限的表示形式。
A kernel keyset is a representation of a collection of kernel keys and the desired read or write access to them.
前面描述了预定义的内核键集，它们应该可以构成典型的替换门的基础。

但是只要1级驱动程序支持扩展的获取和键集驱动游标，它就可以支持动态集。
However, a Level 1 driver can support dynasets if it supports extended fetch and keyset-driven cursors.
这样将至少为索引可以基于中间页中的键集拥有的最大大小的一行留出足够的空间。
This leaves sufficient space for at least one row of the maximum size that the index can have, based on the set of keys on the intermediate pages.
键在内核中的使用很可能会随着时间的推移而发生变化，这可能使得您的键集无法满足将来的需求。
The kernel's use of keys is likely to evolve over time, which could make your keyset insufficient in the future.
产生这种性能问题的原因是，统一odbc使用可滚动的键集驱动游标来发出SELECT语句。
The reason for this performance issue is that Unified ODBC USES scrollable dynamic cursors to issue SELECT statements.
这是必不可少的，因为我们当前未提供定义监测集键之间或者甚至不同监测集之间的关系的功能。
This is necessary because we currently don't provide the capability to define relationships between monitor set keys or even between different monitor sets.
要在多维数据集模型的另一个切片上创建分组集，应该创建一个新的分组集，其中至少要包含新切片中每一级的级键属性。
To create a grouping set at another slice of the cube model, create a new grouping set that includes, at a minimum, the level key attributes of each level in the new slice.
这个程序接受一个操作码和一个记录键作为输入，然后读取VSAM数据集并将记录返回给CICS。
This program accepts an operation code and a record key as inputs, then reads the VSAM dataset and returns the record back to CICS.
在这个非常简单的示例中，通过复制当前呈现参数集并只覆盖一个键，就可以计算新的呈现参数集。
In this very simple example it is possible to calculate the new set of render parameters by copying the current set and overriding only one key.
如果没有找到属性集文件，消息键会使用它本身。
虽然这个监测集可以有多个键，但每个键必须绑定到引用相同业务流程的业务项目属性。
While this monitor set can have more than one key, each key must bind to business item attributes that reference the same business processes.
索引也是一种DB 2对象(一个单独的VSAM数据集)，它由一组排好序的键组成，这些键是从相应表中的一个列或多个列抽取出来的。
An index is a DB2 object (a separate VSAM dataset) that is comprised of an ordered set of keys extracted from one or more columns of the corresponding table.
表的主键和所有惟一索引都必须是相关分区键的超集。
The primary key and any unique index of the table must be a superset of the associated partitioning key.
注意，如果业务项没有正确类型的属性（换句话说，与刚才创建的监控集键相匹配的属性类型），则不会列出它。
Note: if a business item has no attributes of the correct type (in other words, attributes of the type that matches the type of the monitor set key you just created), it will not be listed.
如果此计算需要很长时间，Portlet应该为URL缓存呈现参数，且应使用当前的呈现参数集作为键(请参见下一部分)。
If this calculation takes a significant amount of time, the portlet should cache the sets of render parameters for the URLs and should use the current set as a key (see the next section).
大块的结果集可以进行外部排序，reduce()任务遍历整个排序的数据，把每个唯一的键和分类的结果传递到用户的reduce() 函数子进行处理。
Very large results may be externally sorted. The task iterates over the sorted data and passes each unique key and collated results to the users’s reduce() functor for processing.
通过在交互集名称旁边单击鼠标右键并选择所需的上下文关系，从而定义一个将TradeObject . CustomerID作为其键的上下文关系。
Define a context relationship with TradeObject.CustomerID as its key by right-clicking next to interaction set name and selecting the desired context relationship.
实体集内的每个实体必须要有一个唯一的实体索引键。
Each entity must have a unique entity key within an entity set.
您必须了解在产生的资料集程序码中，如何建立资料库中的外部索引键条件约束和串联行为。
It is important to understand how foreign-key constraints and cascading behavior in the database are created in the generated dataset code.
采用随机键，将连续的粒子位置向量转化为离散的解向量，并通过提出相对最短距离法来评价解集的优劣。
The random key was adopted to change from continuous particle position vectors to discrete solution vectors. And the method of relatively minimum distance was proposed to evaluate the Pareto muster.
剖析、挑选、设计开理的“企业当用集败”计划未败为解决题纲的闭键。
The key to solving the problem is to analysis, select and professional designed "Enterprise Application Integration" program.
通常，该键可以是单值相关集。
如果数据集包含约束(如外键约束)，则可能导致引发异常，取决于对数据集执行操作的顺序。
If a dataset contains constraints (such as a foreign-key constraint) it is possible to cause exceptions to be thrown depending on the order of operations performed against the dataset.
日本的假名字符显现时，全部权，但按暂停键能够切换之间的字符集和数字。
The Japanese Kana characters show up when titling, but by pressing the pause key can you toggle between the character sets and Numbers.
日本的假名字符显现时，全部权，但按暂停键能够切换之间的字符集和数字。
The Japanese Kana characters show up when titling, but by pressing the pause key can you toggle between the character sets and Numbers.
