Logical Restores

Gurus, I am restoring my production backup onto a DR server on a daily basis, which is working fine using OnBar (-r -w -p). However there is a requirement for intra-day restores of the logical logs as they are backed up on the prod server. Can I do regular logical restores on the DR server of the logs from the production server. I have had conflicting answers from different sources at Informix, and my attempts to restore a couple of log backups onto the DR server have failed. I run the command onbar -r -l, but I get the message about there being no down dbspaces to recover. I know they're not down, I dont want them down, they're just "out of date", and I want to load/"play" the logs into the various dbspaces. Any help/advice appreciated. Daniel.
