Informix 7.30 failed to start

I am maintaining a legacy system using informix 7.3. The system has crash recently. At the start of oninit, the logs file shows that there is an error after logical recovery process. Also from oncheck -cR there are invalid entries in the logical log. Is there anyway to skip logical log recovery so the server can start? Or is there another solution? Thanks for the help.

Mohammad, 1. If there is a level 0 archive image around you can simply restore using that image with NO logical log recovery as there is most likely logical log corruption. 2. If not then tech support has the ability to null out fast recovery providing you have a valid support contract but still may cost you time and materials for a version that old. Mark
