安装Oracle 12c,出现OS Kernel Parameter shmall异常 此原因为配置内核参数时出现遗漏,shmall值没有配置. root用户下执行以下操作, [root@liujun~]#vim /etc/sysctl.conf 添加kernel.shmall = 186704这一行 保存退出后,[root@liujun ~]# /sbin/sysctl –p使之生效. 再次点击“Check Again”,弹出如下界面,...
6、/proc/sys/kernel/shmall 该文件是在任何给定时刻系统上可以使用的共享内存的总量(以字节为单位)。默认设置为2097152。 7、/proc/sys/kernel/shmax 该文件指定内核所允许的最大共享内存段的大小(以B(字节)为单位)。默认设置为33554432。 8、/proc/sys/kerneI/shmmni ...

HINT: This error usually means that PostgreSQL's request for a shared memory segment exceeded available memory or swap space, or exceeded your kernel's SHMALL parameter. You can either reduce the request size or reconfigure the kernel with larger SHMALL. To reduce the request size (currently 380...

the system limit for the maximum number of semaphore sets (SEMMNI), or the system wide maximum number of semaphores (SEMMNS), would be exceeded. You need to raise the respective kernel parameter. Alternatively, reduce PostgreSQL's consumption of semaphores by reducing its max_connections parameter...
If this parameter is NULL, the kernel determines the address to start. length Indicates the length of the mapping, in bytes. prot Indicates the permission to be granted on the mapping area. The permission to grant must not conflict with the open mode of the file. The value of this ...

The PostgreSQL documentation contains more information about shared memory configuration. 我搜索并查看了文档,但我尝试设置kern.sysv.shmmax和kern.sysv.shmall的所有工作都正常。 Snow Leopard的正确设置是什么?我用macports安装了postgres。
