Logical log restore question

Hi, I am trying to set up the backing up of logical logs using an alarm script. I use ontape -a in the script to backup to a disk file, then rename it using the number of the logical log that was backed up (or the number of the first if multiple logs were backed up, although this would rarely happen) as part of the file name. What do I do at restore time? I was hoping that I could just concatenate the backed up logs and restore them in one go, but that does not seem to be happening. Informix will just restore the first one -- I suspect there's a record at the end of each log file that tells ontape that it has reached the end. The alternative is to copy the log files one by one every time ontape asks if I want to restore another log tape. The problem is I can accumulate > 100 logs within a day (level 0 archives are taken daily). Has anyone used a (semi-)automated script to restore a large number of logical logs? Any suggestions appreciated. TIA Gabor Heppes
