本文档所含信息适用于所有平台
用途
这篇文档帮助确定 ORA-2730x 错误可能发生的原因，并提供可用的解决办法。这类错误通常是由于操作系统调用错误或者操作系统配置问题引起的，形式如下：
ORA-27300: OS system dependent operation:%s failed with status: %s
ORA-27301: OS failure message: %s
ORA-27302: failure occurred at: %s
你可以参考各自的操作系统手册，来理解 Unix 系统错误的背景信息。例如：
http://www.ibm.com/developerworks/aix/library/au-errnovariable/
请注意只有少数的错误适用于所有基于 Unix 的平台。有可用的 OS 级别的文档来介绍一些独立的操作或者 OS 调用，例如fork（）或 semget（）。ORA-27300 错误中的‘status’通常对应一个 Unix 错误代码，这个错误代码定义在 OS 的头文件“errno.h”中 ，由 OS 调用返回。
例如：
ORA-27300: OS system dependent operation:fork failed with status: 11
“man fork”显示：
The fork() 函数会失败，如果：
EAGAIN (status 11)：系统缺少创建一个进程的必要的资源，或者系统强制限制整个系统运行的进程的总数，或某个用户{CHILD_MAX}运行的进程的总数。EAGAIN 对应 status 11。
The fork() 函数会失败，如果：
ENOMEM (status 12)：可用的存储空间不足。

ORA-27302: failure occurred at: sssxcpttcs6
参考 BUG: 6991131 - Status: 32,Not a Bug
这是 shutdown 过程中发生的问题。我们给 MMON 发送 shutdown 命令，然后等待30秒来检查它是否关闭。如果它仍然存在，那么我们收集诊断信息并试图挂起目标线程（在这个例子中是“MMON”）。然而我们发现目标线程句柄已经无效了，因为这个线程已经退出或即将退出。这样导致这个错误显示在报警日志中。这个错误在 shutdown 的过程中可以被忽略，只要它不会 hang 住，因为目标线程在我们尝试收集诊断信息的时候已经消失了。
