Setting up Rootdbs on a raw disk

Hi all, I got the part about setting up databases on raw files. I understand that using links is the way to go. What I am having problems with is actually getting it to work. I created a link to a raw disk. ln /dev/rdsk/c0t2d0p3 /dbdisk/rootdisk (I also tried ln -s). When I try to initialize the database - oninit -i or through onmonitor I get the error "Error opening file "dbdiisk/rootdisk" I know that I must be missing some obvious step (and probably silly). Any ideas?

Besides the apparent typo that Octav caught, have you checked the permissions on the underlying RAW device? It MUST be owner and group 'informix' and perms 660. Remember for symbolic links ls -l shows ownership and permissions for the LINK not the underlying file or device. Use ls -lL to see permissions of the file/device pointed to by the link. Art S.

Any ideas? > a) use ln -s as it is more readable when you do an ls -l otherwise it is very hard to check what it is linked to (At least under SCO you have to do an ncheck -i <inode-number> and it scans EVERY directory on the file system to find the links, take ages!!). b) As others have suggested checking the spelling, also c) /dev/rdsk/... will be a ln -s type link to a file in /devices do chown informix /devices/... chgrp informix /devices/... chmod 660 /devices/...,raw (NOTE: /dev/rdsk/... links to /devices/...xxx[a-h],raw /dev/dsk links to /devices/...xxx[a-h] to enable KAIO (faster) you want the ...,raw device) then you need to fix the permissions on the links chown -h informix /dev/rdsk/... chgrp -h informix /dev/rdsk/... chown -h informix /dbdisk/... chgrp -h informix /dbdisk/... the -h option changes the link rather than what the link points to ls -l /dbdisk should show rwxrwxrw informix informix ... ls -l /dev/rdsk/xxxxx,raw should show rwxrwxrwx informix infromix xxx -> /devices/yyy ls -l /devices/yyy should show rw-rw---- informix informix ....,raw Phew!
