RE: Re[2]: ORDER -- was Re[2]: Sequences in OPS/RAC

How about removing any holes via some sort of batch process, ie: Insert into staging tables using any old sequence, don't worry about gaps. Then, periodically upload this to the main tables using either a sequence or a local pl/sql counter. I can think of a number of variations on this theme.
