ONLOAD/ONUNLOAD QUESTIONS

Hi all, I need to make a copy of the database on the production machine to the development machine. I cannot restore a level 0 since, my dbspace structures are different ( we recently added new disks/dbspaces on prod m/c ). Here are my questions 1. If I use ONUNLOAD to unload to tape, will it lock the database in exclusive mode ( I tested it on my dev m/c and it doesn't ), but the Migration guide ( 7.2 ) says that is does 2. The database on the source m/c is on 3 dbspaces and the dev on 2 dbspaces. How will ONLOAD handle this. Can it load on to 2 dbspaces ? And how will it know what data to load onto each dbspace. Anyway, seems to me that ONLOAD/ONUNLOAD may not work. So, I may have to use the DBEXPORT/DBIMPORT method, but I understand that DBEXPORT locks the database in exclusive mode. Is that true ? I need to have people accessing the database while I am running my entire copy process. The only other alternative I can think of is to write dbschema and load for all tables ( 1000 of them ). Can anyone think of any better solutions ???
