However, keep in mind that buffer pools are part of the database Shared memory set.
但是请记住,缓冲池是数据库共享内存集中的一部分。
This is much less then any database Shared memory set available to other UNIX platforms.
这比其他UNIX平台上可用的任何数据库共享内存集要少得多。
For example, the locklist is a memory pool that belongs to the database Shared memory set.
例如,locklist是属于数据库共享内存集的一个内存池。
For example, the lock list is a memory pool that belongs to the database Shared memory set.
例如,locklist是属于数据库共享内存集的一个内存池。
These limits dictate how we configure each of the memory pools in the database shared memory set.
这些限制规定了我们该如何配置数据库共享内存集中的每个内存池。
If UDB is configured to create a database Shared memory set which is larger than this, the request will fail.
如果将UDB配置为创建一个大于该值的数据库共享内存集,则请求将遭到失败。
If DB2 is configured to create a database Shared memory set which is larger than this, the request will fail.
如果把DB2配置成创建大于这个值的数据库共享内存,那么请求就会失败。
Application group Shared memory set is not listed because it is allocated from the database Shared memory set.
应用程序组共享内存集没有列出,因为它是从数据库共享内存集中分配的。
For example, the buffer pools and the database heaps are two separate memory pools within the database memory set.
例如,缓冲池和数据库堆是数据库内存集内的两个不同的内存池。
To resolve the problem, run UDF in an unfenced mode or reduce database Shared memory set to no more than 5 segments.
要解决这个问题,可以在unfenced模式下运行udf,或者将数据库共享内存减少至不多于5个段。
The following output indicates 42 MB of memory is reserved for the instance shared memory set (10313 pages * 4096 bytes per page)
下面的输出表明有 42MB 的内存被预留给实例共享内存集(10313页 * 4096字节/页)
Limit: Because the physical RAM is only 1gb, the database Shared memory set can only map to what is physically available to it, which is 1gb + swap space.
限制:由于物理ram只有1gb,数据库共享内存集只能映射到它在物理上可以使用的空间,即1gb +交换空间。
In practice, the amount of memory set aside for survivor space is adjusted on the fly depending on the percentage of objects that survive each collection.
实际上,预留为幸存者空间的内存量会根据在每次收集中幸存下来的对象的百分比进行实时调整。
The agent private memory set consist of the following memory pools. Their sizes are specified in the database configuration parameters enclosed in parenthesis.
代理私有内存集由以下内存池组成。
Depending on the type and size of the segment, DB2 can specify to create it in quadrant 4. The database Shared memory set is still limited to approximately 1gb.
根据段的类型和大小,DB 2可以指定在象限4中创建段。数据库共享内存集仍然有大约1gb的限制。
Applications that frequently access the data in this memory set (currently limited to the database working set) will likely experience a performance improvement.
经常访问该内存集(目前限制为数据库工作集)中的数据的应用程序将极有可能体验到性能改善。
The above example showed that although 42 MB is memory is reserved for the instance Shared memory set, only about 21 MB is being used at the time db2mtrk is run.
上面的例子表明,虽然预留给实例共享内存集的内存有42MB,但在db2mtrk运行时只用到了大约21 MB。
Limit: Any request by DB2 to create a database share memory set which is larger then the shmmax value (2gb in this case) will fail with an out of memory type error.
限制:DB2发出的任何创建大于shmmax值(这里是2gb)的数据库共享内存集的请求都将失败,并返回一个outofmemorytype错误。
As physical memory on today's workstations get larger and larger, the table used for memory translation must consume more and more resources to map the working memory set.
随着当今工作站上的物理内存越来越大,用于内存转换的表必须消费越来越多的资源,以映射工作内存集。
In a recall task, the person learns the memory set and is then asked to reproduce the items from memory without any cues (e. g., "List all the aircraft in the sector.").
在回忆任务中,你学习那些记忆组并在没有任何提示下从记忆中把记忆组的各个项目给重新列出来如:“请列出扇区中的所有飞机。”
RAM is this memory recall or, as you'll soon find in problems set one, that's used for ephemeral purposes.
内存是随机存储器,你们很快就会在习题集一中发现,它是用来短暂存储的。
When you have done this, try to organize your life so that the time set aside for learning coincides with the time when your memory is at its best.
当你这样做的时候,试着规划你的生活以便留出学习的时间,这个时候也应是你的记忆最好的时候。
Another set of participants had to count backward from 1,000 by nines as they watched the clips, occupying their conscious working memory.
另一组参与者在观看视频片段时必须从1000开始倒数,依次减9,这占据了他们有意识的工作记忆。
If you specify a number between 18 and 4096, the queue manager USES the number specified to set the memory allocated.
如果指定的值在18到4096之间,队列管理器将使用指定的数字设置所分配的内存。
Its successor was the 4040 processor (released in 1974), which had an expanded instruction set, program memory, register set, and stack.
其后面是4040处理器(1974发布),其具有扩展指令集、程序内存、寄存器集和堆栈。
