Hi,

The IDS, not start-up because the chunk '/home/informix/dbspaces/rootdbs', not exist.
Please check the ONCONFIG file and definition allocate espace, before start-up, run oncheck -pr to see errors posibles.

Rgds,

Hello,

Ddi you give the permission to the file rootdbs to informix after touching it? Give 770 to informix.

Bye

Nitin

Hi,
Yes, here is the permission file :

[informix@handel dbspaces]$ ls -al
-rwxrwx--- 1 informix informix 0 Mar 18 11:11 rootdbs

Thks for advance

Hello,

Is this the first time that the informix instance is coming up? Or it was running earrlier and suddenly the instance is down. If the instance has crashed and then you have touch the rootdbs file, then I suppose you will have to restore the last level 0 and start the instance.

If it is the 1st time you are initializing the instance, then change the name of the root chunk to say ifxroot in onconfig file, touch a new file in the directory and give permission as 770 to informix and start the instance with oninit -iv (remember, it will delete all the data and initialize the instance).

Bye

Nitin

Hello,

I feel you have not given the ROOTPATH correctly. It should be:

ROOTPATH /home/informix/dbspaces/rootdbs

bye

Nitin

Rdgs,

Hi,

Please change following:
ROOTNAME rootdbs
ROOTPATH /home/informix/dbspaces/rootdbs.
The file /home/informix/dbspaces/rootdbs, must exist and permissions 660 (chmod 660 /home/informix/dbspaces/rootdbs )
Next run oninit -v

Gustavo.

Hi,

Excuse me, must be:

ROOTPATH /home/informix/dbspaces, then run chmod 660 /home/informix/dbspaces.

Gustavo
