每五秒钟查询一个可用物理内存并将结果写入日志文件。
Every five seconds, query the available physical memory and write the result to the log file.
垃圾收集器将尝试适当调整堆的大小，但将避免使用同一机器上多半的可用物理内存。
The garbage collector will try to size the heap appropriately, but it will avoid using more than half the physical memory available on the machine.
由于可寻址内存的范围从数百到数十亿gb，可用物理内存(RAM)的限制变得更加重要。
With addressable memory in the range of hundreds to billions of gigabytes, it is the available physical memory (RAM) limitation that becomes much more important.
但是不同的应用程序或同一应用程序的不同实例可以放在不同的内存窗中，并消耗系统上更多的可用物理内存。
But different applications, or distinct instances of a single application, can be placed in different memory Windows and consume more of the available physical memory on the system.
因此，我们只能分配最多1gb(可用的物理ram)的共享内存给数据库使用。
Therefore, we can only allocate up to 1gb (physical RAM available) of Shared memory for database use.
由于要在RAM和分页空间之间进行选择，在RAM可用的情况下，大多数人显然都更希望使用物理内存。
Obviously, given the choice between RAM and paging space, most people would prefer to use physical memory, if the RAM is available.
如果同时启动数据库A和数据库B，我们将请求至少 1.55GB (898MB + 656MB)的可用物理RAM，以便同样地将共享内存固定在 RAM 中。
When both database A and database B is started simultaneously, we will require at least 1.55GB (898MB + 656MB) of physical RAM available for shared memory to pin against.
在配置IDS内存时，我们需要考虑总的可用内存，包括物理ram、虚拟内存和系统上的日常负载。
When configuring IDS memory, we need to consider the total available memory, both physical RAM and virtual memory and daily load on the system.
如果缓冲池大小过大，那么内存使用会超过可用的物理内存，从而导致操作花费更多时间对内存进行分页。
If you set the buffer pool size too high, then system memory usage will exceed the available physical memory, causing the operating system to spend more time paging the memory.
Linux包括了管理可用内存的方式，以及物理和虚拟映射所使用的硬件机制。
Linux includes the means to manage the available memory, as well as the hardware mechanisms for physical and virtual mappings.
在虚拟环境中，节约出来的内存可用于支持其他已虚拟化的服务器，从而提高物理硬件的利用率。
In a virtualized environment, this memory could be used to support additional virtualized servers, thus improving the utilization of the physical hardware.
这可能是因为该过程总共需要375MB的内存，严重超出了可用的物理内存。
This is probably because the process had a total memory footprint of 375mb, substantially more than the physical memory available.
前面命令中指定的内存限制是指系统中可用的“物理”内存。
The memory limits specified in the previous commands refer to the "physical" memory available in the system.
以物理处理器为单位的处理容量，可用于内存压缩活动。
The amount of processing capacity in units of physical processors that would be used for memory compression activity.
可用内存包含不同VM对象联系在一起任何地址空间物理内存的页。
The free list contains pages of physical memory that are not associated with any address space of VM object.
可用内存包含不同VM对象联系在一起任何地址空间物理内存的页。
The free list contains pages of physical memory that are not associated with any address space of VM object.
