oninit error : cannot open chunk /dev/online_root

[hoctro]

17:37:08 Cannot Open Primary Chunk '/dev/online_root', errno = 2
oninit: Cannot open chunk '/dev/online_root'. errno = 2
oninit: Fatal error in shared memory initialization

Does anyone have this error ?? and how do you resolve it ?

Thanks

hoctro,
You do not say what type of OS you are operating and whether you are starting an existing instance or creating a new one.
The first thing I would look at in Unix, based on your error messages, are the permissions on the chunk /dev/online_root - they should be 660. If the permissions are OK (again in Unix) take a look at your error message files from the system for messages involving your chunk. These are in various places for different Unix boxes (e.g., Sun has them in /var/adm/messages).
If this is not Unix (I don't recognize Dynamic server 2000 - maybe that is for Win 2000?) I'm not sure I can help you.

I do not know hoctro run on what OS However, I encounter the
same error message too when i tried to start to create a new instance and i am sure it is not due to the permission . I am running informix engine run on redhat 6.2, help please???
