Error Message:PRVF-7543 : OS Kernel parameter "semmni" does not have proper value on node "localhost"

回答: 错误信息PRVF-7543表示在节点"localhost"上，操作系统内核参数"semmni"的值不正确。\[1\]这个错误的原因是内核参数的值不符合要求。解决方法是修改内核参数的值以满足要求。\[1\]在RHEL/OEL 5上，默认已经配置了一些内核参数的默认值，包括kernel.shmall和kernel.shmmax。\[2\]然而，Oracle Database 11g release 2在RHEL/OEL 5上需要特定的内核参数设置。这些设置包括kernel.shmmax、kernel.shmall、kernel.shmmni、kernel.sem等。\[3\]其中，kernel.shmmax的最小值为4294967295，kernel.shmall的最小值为2097152，kernel.shmmni的最小值为4096，kernel.sem的值为250 32000 100 128。请根据这些要求修改内核参数的值以解决PRVF-7543错误。
