初始化informix实例时报错：

配置文件$ONCONFIG 里配置共享内存配置是？

大梦

核心参数太小吧!

lizhuo

onconfig里是默认的值，大梦所说的核心参数是指操作系统的吗？
初次使用informix，在linux上，x86。

SHMVIRTSIZE     8192         
SHMADD          8192            
SHMTOTAL        0            
在onconfig文件里没有找到buffer

把online.log的出错信息贴出来看看

elei1151

是BUFFERS，将该值改为物理内存的20%至25%
