when you do so, make sure the number of common paging space devices matches the number of redundant shared memory partitions.
如果这样做,一定要确保共用分页空间设备数量与冗余的共享内存分区的数量匹配。
so far we have discussed the instance shared memory, the database shared memory, the application group shared memory and the agent private memory.
至此,我们已经讨论了实例共享内存、数据库共享内存和应用程序组共享内存以及代理私有内存。
there is one application group shared memory set per application group; it is shared by all agents belonging to that application group.
每个应用程序组有一个应用程序组共享内存集,由属于该应用程序组的所有代理共享。
there is one instance shared memory set per instance; it is shared by all databases within this instance.
每个实例有一个实例共享内存集,由这个实例中的所有数据库共享。
since the end address of the instance shared memory is not fixed, the starting address for the database shared memory is not fixed either.
因为实例共享内存的结束地址不固定,所以数据库共享内存的起始地址也是不固定的。
there is one database shared memory set per database; it is shared by all agents connected to this database.
每个数据库有一个数据库共享内存集,由连接到该数据库的所有代理共享。
you can have a mix of common and independent paging space devices in a shared memory pool.
在同一个共享内存池中,可以同时有共用的和独立的分页空间设备。
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。
the overflow buffer is used to satisfy peak memory requirements for any heap in the instance shared memory region whenever a heap exceeds its configured size.
每当某个堆超出了其配置的大小时,便可以使用溢出缓沖区来满足实例共享内存区内任何堆的峰值需求。
there is one database shared memory set per database.
每个数据库有一个数据库共享内存集。
tip: if you create one database per instance, you can effectively allocate up to 1gb of database shared memory for all your databases.
提示:如果为每个实例都创建一个数据库,就可以有效地为所有数据库分配最多1gb的数据库共享内存。
this total has to include the text, data, and stack segments, plus all shared memory regions.
这个总数必须包括文本、数据和栈段,再加上所有的共享内存区域。
shared memory provides the fastest method of interprocess communication, because it processes read and write messages at the speed of memory transfers.
共享内存提供了最快地进行进程间通信的方法,因为它以内存转换的速度来处理读写消息。
it is important that the database shared memory and stack do not collide.
使数据库共享内存和堆栈不发生沖突,这一点很重要。
you can use this number to free up the shared memory used by this library.
不过可以使用这个数字来释放这个库所使用的共享内存。
not all installations of php support shared memory because it can be a security risk.
并不是所有的php安装都支持共享内存,因为它可能是安全风险隐患。
this is well under the 1.75gb shared memory limit, and each database shared memory segment can safely map contiguously to a quadrant.
这低于1.75gb 的共享内存限制,并且每个数据库共享内存段可以安全地连续映射到一个象限。
its constructor creates the shared memory and objects in it.
它的构造函数创建共享内存及其中的对象。
limit: in this configuration, the limit for database shared memory is 2gb, or 8 segments.
限制:在此配置中,对于数据库共享内存的限制是2gb或8 个段。
however, shared memory does not provide any access control for processes that use it.
不过,共享内存不为使用它的进程提供任何访问控制。
the shared memory available per instance, then becomes, 1gb plus whatever space is still available in quadrant 4.
于是,每个实例的可用共享内存就变为1gb加上象限4中仍然可用的空间。
this works well for a relatively small number of cpus, but a problem with the shared bus can occur if you have dozens, and even hundreds, of cpus competing for access to the shared memory bus.
在cpu数量不多的情况下,这样没有问题,但如果有几十个、甚至几百个cpu,这些cpu争用对共享内存总线的访问,那么共享总线在这一点上就会出现问题。
this class stores the shared memory identifier.
这个类存储共享内存标识符。
