初始化数据库的问题
执行oninit-ivy后报错误信息：Could not fork a virtual processor: errno = 12 系统配置，参数配置。。online.log信息。。PLS 在linux上
#define ENOMEM 12 /* Out of memory */
应该是配置有问题，看看BUFFER和SHMVIRTSIZE。

硬件有多少内存、CPU？操作系统是什么？执行oninit -i 后，online.log里是怎么写的？ AIX操作系统；

。。。。似乎你的空间存在些问题
ROOTSIZE > PHYSFILE+ LOGFILES * LOGSIZE ，并且还需要有空间。。。
