onload: Getting a Table of Contents without actually loading

Hi All, Our company is looking at improving the internal procedures and would like to know what other administrators are doing to try and streamline processes. Unfortunately, I am not too familiar with Informix backup and restore commands, so I'd appreciate some guidance from other sys admins. At present, I have several databases that are copied to different tapes using the Informix onunload command below as user informix: onunload -t /dev/rmt0 -b 16 -s 20000000 sampledb Typically, to verify what data is on this tape, our past procedures required that we drop a test database we had in an established database and replace it with the loaded data from the command below: onload -t /dev/rmt0 -b 16 -s 20000000 -d datadbs sampledb What we would like to do is view a table of contents of what is on the onunload tape and somehow verify it without doing the actual load. Is this possible? If so, what commands should I be investigating? We are on an AIX 5 system using Informix Dynamic Server 9.30 UC2. TIA. Steve
