然后rootdbs、rootpath、tmpdbs也都修改了，和第一个实例也不一样。
不知道是哪些参数配错了。内存什么情况下会重合呀？
另外因为第一个实例正在运行，我用ipcs -a|grep informix，如果我ipcrm的话，会不会影响第一个实例呀？

基于你提供的信息来看17:56:16create_vp: cannot allocate semaphore
18:10:25IBM Informix Dynamic Server Started.
18:10:25semget: errno = 28
是受资源限制了...至于具体是什么原来.得看你的系统 errno = 28 是什么?
在hp-ux下errno可以在/usr/include/errno.h 里看到.....其它的太清楚.
[ 本帖最后由 liaosnet 于 2009-12-17 22:32 编辑 ] 我把第一个实例停了，想验证一下是否是系统资源分配的问题，话说初始化，之前的报错没了，但是停在了一行不动了，我查看数据库状态是online状态

正常！ 初始化第二个实例的时候报这个错误了？请问对于初始化成功的rootdbs（online），再次初始化这个rootdbs会出错误吗？比如造成裸设备故障？（我误操作了，之前第二个实例都online了，结果我打成oninit －viy了）
