change the permission of the device to the database ownership (like on the already existent RAW devices) and initialise them from within the database ... thats it

Ok, great!
One more question.
When i create logical volume, it is by default created as block device.
But i see that all my raw devices assigned to the database are character-special devices.
Example, in my /dev directory i have following:
brw-rw---- 1 root system 10, 12 Dec 09 2005 lvinformix0

crw-rw---- 1 informix informix 10, 12 Mar 16 06:30 rlvinformix0

From a given example, only the rlvinformix0 device is assigned to the database.
So, how do i make this new LV to be a character device?

NAME
lvremove - remove a logical volume SYNOPSIS
lvremove [-A|--autobackup y|n] [-d|--debug] [-f|--force] [-h|-?|--help] [-t|--test] [-v|--verbose] LogicalVolumePath [LogicalVolumePath...] DESCRIPTION
lvremove removes one or more logical volumes. Confirmation will be requested before deactivating any active logical volume prior to removal. Logical volumes cannot be deactivated or removed while they are open (e.g. if they contain a mounted filesystem). Removing an origin logical volume will also remove all dependent snapshots. If the logical volume is clustered then it must be deactivated on all nodes in the cluster before it can be removed. A single lvchange com- mand issued from one node can do this. OPTIONS
See lvm(8) for common options. -f, --force Remove active logical volumes without confirmation. EXAMPLES
Remove the active logical volume lvol1 in volume group vg00 without asking for confirmation: lvremove -f vg00/lvol1 Remove all logical volumes in volume group vg00: lvremove vg00 SEE ALSO
