de·fragment·er 英ˌdɪfræg'mentə美ˌdɪfræg'mentə COCA²⁴⁰⁰²⁹BNC²³⁶²¹³⁺¹iWeb⁵⁰¹⁴⁹ 基本例句 n.计磁盘修复器 A crash while the defragmenter is running results in only the last transaction being aborted. 仅在最后的事务被中止时,碎片整理程序才会发生故障。 ibm A solid example of file fragmentation with a single hard drive can be shown simply by running a disk defragmenter on your own computer. 比如,只需在计算机上运行一个磁盘碎片整理程序就能看到单个硬盘的文件碎片。 blog.sina.com.cn The defragmenter merges multiple smaller extents to get longer contiguous extents for a partition, thereby reducing the total number of extents in a partition. 碎片整理程序将分区中的多个小区段合并成较长的连续区段,从而减少分区中总的区段数量。 ibm The defragmenter uses the buffer pool for this movement in order to keep the data in sync with other uses. 在移动时,碎片整理程序会采用缓存池来保持与其他使用的同步。 ibm What does the defragmenter do? 碎片整理程序的作用是什么? ibm Archives, reads, and updates can be run in parallel with the 11.70 defragmenter. 存档、读取、和更新可与11.70碎片整理程序并行运行。 ibm Certain special operations on a partition conflict with the 11.70 defragmenter. 某些特定的分区操作会与11.70碎片整理程序冲突。 ibm Checkpoints are not blocked by the defragmenter. 检查点没有被碎片整理程序阻塞。 ibm Click Analyze to start the Disk Defragmenter. 单击分析启动磁盘碎片整理程序。 yeeyan Conflicting operations result in the defragmenter returning an error code. 如果存在与碎片整理程序冲突的操作,将返回错误代码。 ibm Extents added while the defragmenter is running will not be eliminated. 在碎片整理程序运行时增加的区段将不会被清除。 ibm Free space at the end of the partition is considered as space that needs to be covered by the defragmenter. 分区末端的空闲空间要作为碎片整理程序所涵盖的空间来考虑。 ibm How does the defragmenter work? 碎片整理程序如何工作? ibm However, compress, repack, and shrink operate at the row level; the defragmenter operates at the extent level. 然而,压缩、重新打包、和收缩在较低级别运行;碎片整理程序在区段级别运行。 ibm If a table is used heavily and is frequently updated, then you should consider periodically running the defragmenter on it. 如果表的使用非常频繁,并经常更新,那么可以考虑在该表上定期进行碎片整理操作。 ibm If the largest free extent cannot cover two or more partition extents, the defragmenter sets an error code and returns. 如果最大的空闲区段无法涵盖两个或更多分区区段,碎片整理程序会设置错误代码并返回。 ibm If the partition has one or zero extents, then no defragmentation can be performed; the defragmenter returns successfully with no error code set. 如果分区没有或仅有一个区段,那么就不会执行碎片整理;碎片整理程序会返回不含错误代码的成功操作。 ibm If buffer pool usage is a concern, then running the defragmenter at a non- peak time is recommended. 如果缓存池的使用存在问题,那么建议在非高峰时间运行碎片整理程序。 ibm If this is undesirable, then run shrink before running the defragmenter on a partition. 如果这样不可取,那么可以在运行碎片整理程序之前在分区上运行收缩。 ibm In order to successfully revert, you will be required to run defragmenter on such partitions. 为了成功降级,您需要在这个分区上运行碎片整理。 ibm In the Disk Defragmenter dialog box, click the drives that you want to defragment, and then click the Analyze button. 在磁盘碎片整理程序对话框中,单击你要整理的驱动器,然后点击分析按钮。 yeeyan Once the defragmenter finds a free extent that can cover two or more partition extents, it moves pages from the old extent into the new extent. 一旦碎片整理程序找到了能够涵盖两个或多个区段的空闲区段,它会将页从旧区段移动到新区段。 ibm So compress, repack, and shrink might be able to reduce the total number of extents for a partition, just like the defragmenter. 因此,压缩、重新打包、和收缩可能会像碎片整理程序一样,能够减少分区总的区段数量。 ibm The defragmenter will not automatically start up again if a defragmentation operation was in progress at the time of crash. 在碎片整理操作正处于故障当中时,碎片整理程序不会自动再次启动。 ibm The defragmenter does not take an exclusive lock while doing the defrag operation, hence the partition is available for other operations. 在进行碎片整理操作时,碎片整理程序不会执行独占锁,这样分区对于其他操作来说也是可用的。 ibm This command must be run while the defragmenter is active on a partition to show the defragment operation in progress. 必须在已启动碎片整理程序的分区上运行该命令,来查看正在进行的碎片整理操作。 ibm To avoid this degradation in performance, you should run Disk Defragmenter weekly or biweekly. 要避免性能的降低,您应该每周或每两周运行一次磁盘碎片整理。 ibm Defragmenter transactions are short; there is no possibility of a long transaction occurring. 碎片整理事务很短;不可能出现一个长事务。 ibm |
