A pbuf is a pinned memory buffer.
pbuf是一个固定内存缓冲区。
AIX treats large pages as pinned memory and does not provide paging support for large pages.
AIX把大页面当作固定内存对待，对于大页面不提供分页支持。
Lvmo allows you to change the pbuf, or pinned memory buffers, used for each volume group, and therefore shows and allows control over the memory used to cache volume group data.
可以使用lvmo修改每个卷组的pbuf(即固定内存缓冲区)，可以显示和控制用来缓存卷组数据的内存。
As a result of this change, there is less pinned memory and fewer processes that are running on the system; both have positive affects on overall systems performance (see Listing 12).
这项更改带来的结果是，固定内存变得更少，并且系统中运行的进程也变得更少；这对于整体系统性能来说，都具有积极影响(请参见清单12)。
Another common problem with allocating database Shared memory on Solaris is due to the fact that all pages of a Shared memory segment are pinned in physical RAM.
Solaris中另一个与分配数据库共享内存有关的常见问题是由于这样的一个事实导致的，即共享内存段的所有页都是固定在物理ram中的。
Kernel variables limited to those pinned in memory.
内核变量仅限于内存中驻留的变量。
pin—number of 4K pages mapped into memory and pinned (pin is a subset of inuse)
pin ——映射到内存中的、且固定的4K分页的数目（pin是inuse 的子集）
In unsafe mode, you can allocate memory on the stack, where it is not subject to garbage collection and therefore does not need to be pinned.
在不安全模式，您可以配置在堆叠上的记忆体；那里并不需要交付给记忆体回收，因此不需要固定。
