Re: Cannot Rollforward from Checkpoint

The shared memory message is a red herring. The real issue is that you don't have a checkpoint in the logical log where the reserved page says it should be (or it isn't the right format). Unless you've recently upgraded versions, this is almost certainly a bug. Your options are to restore an archive (and if you've recently upgrade, you might still be out of luck) or get Informix tech support to dial in and fix it.
