Usermod Utility
Ingres now includes a usermod utility that allows users to run the modify commands on user tables. Like sysmod, which modifies system catalogs, this utility is useful for maintaining user tables on a regular basis.
Running this utility regularly, or when the table has excess overflow pages, improves performance of user applications.
