系统治理：启动时Oracle 错误 7306 - shmget，共享内存
问题描述
拥有Oracle逻辑卷组的测试系统上碰到一个问题，在启动Oracle 时，出现Oracle 错误号7306:
07306, 00000, sms1sg: shmget error, unable to get a shared memory segment.
原因： shmget 错误。代码没有为整个的SGA找到足够大的单个段，由于致命错误导致无法继续下一个分配模型。
措施：检查返回的错误号，确认系统上有足够的可用共享内存，可满足整个SGA的要求。
是否有补丁程序能够解决这个问题?

SYS ADM: On startup, Oracle error 7306 - shmget, shared memory
Problem Description
I am having a problem on a test system that has logical volume groups for Oracle. When bringing Oracle up, I receive Oracle Error Number
7306:
07306, 00000, sms1sg: shmget error, unable to get a shared memory segment.
Cause: Error in shmget. The code fails to find a single segment large enough for the entire SGA, but cannot continue to the next allocation model because of a fatal error.
Action: Check errno returned. Verify that enough shared memory is available on the system to fit the entire SGA.
I there a patch for this problem?
