Explanation: This is an issue with Space Manager 6.2. When the ROWID method is used in LiveReorg, all the columns will be set to NOT NULL. The program "thinks" that all the columns are the ROWID column (which should be set to NOT NULL). Fortunately, the use of the ROWID method is now very restricted. If there is no suitable index or constraint for replication, LiveReorg will use the "all columns" method and not the ROWID method unless there is a LONG column and the QSA parameter ALLOW_LONG_WO_UNIQUE=NO.
Pre-requisite: You must be sure that no rows in the table are made unique by the LONG or LOB columns.
