新建第二个实例

weikunbei

servernum已经修改了，正在跑的是0，新建的这个是3，不是一个数值。
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
17:56:16  create_vp: cannot allocate semaphore
18:10:25  IBM Informix Dynamic Server Started.
18:10:25  semget: 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.

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）

初始化另外一個實例，需要將正在運行的實例關閉。不然會報共享內存錯誤。
