Ok. Look when you start the Load utility on a single table, the utility holds a X (exclusive Lock) on that table. So you should n't try to load all the files to the same table at the same. You can write a shell script which will pick the files one by one and process them with the LOAD command. Or you can try that manually. You can just type "GET SNAPSHOT" in the IBM Manual for V8 or V9. It will give you example with commands on how to take Snapshot on Locks.
