Module

Modules are supported since DB2 9.7. The conecpt of a modul is similar to the package concept in an Oracle. It’s a collection of functions, procedures, types and variables.

It’s possible to create your own modules by the CREATE command. Add and remove objects in a module by the ALTER command, or to remove an module by the DROP command.

DBMS_UTILITY module
