RE: Cleaning database

I should use to clean database and reclaim storage/disk space?


CLRPFM?? ***I'm kidding!!!!

Seriously, what do you mean by "clean" the database? Like any relational
database you can't just purge rows in one table w/out regard to other
tables. And to make matter worse, most System i tables I've seen do not
have declarative referrential integrity setup, so an attempt to delete
an order that has order details will not fail. 

Many companies have processes to purge old data, or move "historical"
rows into another table or database, but these aren't simple OS/400
commands.
