RE: Runtime for deleteing lots of records

Ah, right, Jim. It's something the system determines the need of - as usual, the 400 does a lot for us. But it still needs to be done, and Leif suggested that it's done often. Is it a manual process in other RDBMS'?

rebuild or update an index on the AS/400 to deal with high volumes of

Jim, doesn't the 400 also balance the index tree from time to time? If it's
smart enough only to remove entries in the index for deleted records,
eventually the tree could get severely skewed, I would think, and require
balancing.
