Shmat failed because of 0x000000c, which is ENOMEM or the available data space is not large enough to accommodate the Shared memory segment.
shmat失败于0x000000c，即ENOMEM或可用数据空间不足以容纳共享内存段。
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。
It adds the creation of the named memory segment, the registration of a callback function, and the writing to files. The memory allocation is shown in Listing 11.
它添加了已命名内存段的创建、一个回调函数的注册、以及文件的写入。
This indicates that the process tried to access a Shared memory segment that was corrupted for some reason, and will crash without calling "fatal_error" or "panic."
这表明，进程试图访问因某种原因已破坏的共享内存段，并将不调用“fatal_error”或“panic”而崩溃。
TLB is used to try and retrieve translation work that has already occurred, and this is the first place the operating system will look for a process's translated memory segment.
TLB用于尝试和检索已经发生的转换工作，而这是操作系统第一次查找进程的已转换内存段的地方。
When the FCM buffers are created in a separate memory segment, the communication between FCM daemons of different logical partitions on the same physical node occurs through Shared memory.
而当在单独的内存段中创建F CM缓冲区时，在同一物理节点上的不同逻辑分区的FCM守护进程间的通信将通过共享存储器进行。
shmat is a UNIX function that attaches the shared memory segment associated with the shared memory identified by shmid (another Solaris function) to the data segment of the calling process.
shmat是一个UNIX函数，它将与 shmid（另一个Solaris 函数）所标识的共享内存相关的共享内存段附加到调用进程的数据段上。
This effectively frees up one segment for database Shared memory.
这将有效地为数据库共享内存一个段。
Segment 2 is for stack and dynamic memory allocation.
