Impact analysis
Use the impact analysis features to discover where objects are used, and what other objects they depend on.
The impact analysis features help you to assess the impact of changes you might make to an object on other objects, or on job designs. For example, before you edit a table definition, you could find the jobs that derive their column definitions from the table definition and consider whether those jobs will need changing too.
There are four types of impact analysis queries:
- where used
- Finds where the selected object is used by other objects. For example, if the selected object is a routine, a where used query lists all the jobs that use that routine.
- where used (deep)
- Finds where the selected object is used by other objects, and also where those objects in turn are used. For example if the selected object is a routine, a where used (deep) query lists all the jobs that use that routine, and also lists any job sequences that use those jobs.
- dependencies of
- Finds the objects that the selected object depends upon. For example, a job might depend upon a particular routine.
- dependencies of (deep)
- Finds the objects that the selected object depends upon, and also what objects they in turn depend upon. For example, a job sequence might depend on a job which in turn depends on a routine.
