从消极的方面看,容器对装入条件和数据请求模式的响应是不可预知的,所以必须在开发过程中添加大量的基于方案的装入测试。
On the negative side, the container's response to load conditions and data request patterns is unpredictable, so extensive scenario-based load testing must be added to the development process.

该CD是由VDM所生成的ISO文件根据VM部署任务模拟的,并且将被装入虚拟光驱,这样它可以比软盘保存更多的数据。
The CD is simulated by an ISO file generated by the VDM according to the VM deployment task and will be mounted to a virtual CD-ROM so it can hold far more data than a floppy disk.
这个父类地址对应于父类类装入器的原始数据结构(叫作shadow)。
This parent address corresponds to the native data structure of the parent class loader (called the shadow).
正如先前描述的一样,悲观方法的意图是确保装入实体bean的数据在整个事务处理持续时间内处于锁定状态。
As described previously, the intent of the pessimistic approach is to ensure that the data loaded into the entity bean is locked during the entire duration of a transaction.
清单5显示了装入数据和显示汇总值的脚本。
Listing 5 shows a script that loads the data and displays summary values.
当结果从FreeDB数据库中返回,它们会被装入到 %found_disks散列中。
Once results are returned from the FreeDB database, they are put in the %found_disks hash.
请把这个模式装入到名为bookdb的数据库。
数据获取:用于获得、清洗、转换和集成数据的ETL(提取、转换和装入)过程。
Data acquisition: ETL (Extraction, Transformation, and Loading) processes to acquire, clean, transfer, and integrate data.
但是请注意,如果需要测试结果访问计划的执行,则仍然需要将尽可能多的数据从生产环境装入测试环境。
Note, however, that if you want to test the execution of the resulting access plan, you will still need to load data from production onto test (as much data as possible).
例如,这可以用来从数据库中装入文档。
This is used, for example, to load documents from databases.
性能也会受影响,因为数据库实在太大,数据库中的任何有效部分都无法装入内存中的缓存。
Performance can suffer because the database is too large for any significant part of it to fit in an in-memory cache.
从数据库中装入人员的任何新实现都不要求在使用工厂和接口的类中进行任何更改。
Any new implementation for loading people from a store does not require any changes in the class that USES the factory and interface.
注意:无法使用IXF文件将导出表装入哈希分区数据库中定义的表。
Note: IXF files cannot be used to load into a table defined in a hash partitioned database.
在众多的事情当中,收集器检查类装入器的数据结构,来判断哪个类是活动的——也就是说,不应当被当作垃圾收集的。
Among other things, the collector examines the class loader data structures to determine which classes are live — that is, are not garbage collectable.

一旦索引表再也无法装入内存,数据库的性能就会直线下降,所以应该尽量升级内存,以便存放那些表。
Database performance plummets once index tables don't fit in memory anymore, so scale up memory as far as possible to hold tables.
