informix onmonitor 时 chunk 指向哪里？？

lunar2000

首先感谢你的回复，

chunk 指向 /usr/informix/dev/chunk1

其他详细信息如下：

Enter the pathname of the root dbspace chunk

ifx

rootdbs1是什么文件？存在吗？

muzx

看看rootdbs1权限是否正确！

我已经找到问题了：

我该如何创建一个新的chunk呢？
我用cat /dev/null >; /usr/informix/rootdbs1
然后就没反应了

Ctrl ＋ Z 终止后，看见那个文件已经50多m了，我是个informix菜鸟，希望大家不吝赐教，谢谢了

lunar2000

已经做到这一步了，下面的问题如何解决：
feptwo>; cat /dev/null>;rootdbs1

feptwo>; ls *dbs*
logdbs1.Z    rootdbs1     rootdbs1.Z   sqgetdbs.ec  tempdbs1.Z   userdbs1.Z

dbssodir:
adtmasks.std  seccfg
feptwo>; cat /dev/null>;logdbs1

feptwo>; cat /dev/null>; tempdbs1

feptwo>; cat /dev/null>;userdbs1

feptwo>; ls *dbs*
logdbs1      rootdbs1     sqgetdbs.ec  tempdbs1.Z   userdbs1.Z
logdbs1.Z    rootdbs1.Z   tempdbs1     userdbs1

dbssodir:
adtmasks.std  seccfg

知道了，权限，informix用户没有权限，需要用root用户来做oninit －vi

# oninit -vi

现在怎么办呀，真郁闷，和oracle差别也太大了：（

join

不会呀，用informix这个用户才可以的。

-2        没有这样的文件或目录。

一个具有上述意义的操作系统错误代码，不可预料地返回到数据库服务器。查找其它操作系统错误信息，它会给出更详细的信息。

那个文件有吗？
